Question

[Solved] Selenium using Python – Geckodriver executable needs to be in PATH

I’m new to programming and started with Python about two months ago and am going over Sweigart’s Automate the Boring Stuff with Python text. I’m using IDLE and already installed the Selenium module and the Firefox browser.

Whenever I tried to run the webdriver function, I get this:

from selenium import webdriver
browser = webdriver.Firefox()

Exception:

Exception ignored in: <bound method Service.__del__ of <selenium.webdriver.firefox.service.Service object at 0x00000249C0DA1080>>

selenium.common.exceptions.WebDriverException: Message: 'geckodriver' executable needs to be in PATH.

I think I need to set the path for geckodriver, but I am not sure how, so how would I do this?

Solution #1:

selenium.common.exceptions.WebDriverException: Message: ‘geckodriver’ executable needs to be in PATH.

First of all you will need to download latest executable geckodriver from here to run latest Firefox using Selenium

Actually, the Selenium client bindings tries to locate the geckodriver executable from the system PATH. You will need to add the directory containing the executable to the system path.

  • On Unix systems you can do the following to append it to your system’s search path, if you’re using a Bash-compatible shell:

      export PATH=$PATH:/path/to/directory/of/executable/downloaded/in/previous/step
    
  • On Windows you will need to update the Path system variable to add the full directory path to the executable geckodriver manually or command line** (don’t forget to restart your system after adding executable geckodriver into system PATH to take effect)**. The principle is the same as on Unix.

Now you can run your code same as you’re doing as below :-

from selenium import webdriver

browser = webdriver.Firefox()

selenium.common.exceptions.WebDriverException: Message: Expected browser binary location, but unable to find binary in default location, no ‘moz:firefoxOptions.binary’ capability provided, and no binary flag set on the command line

The exception clearly states you have installed Firefox some other location while Selenium is trying to find Firefox and launch from the default location, but it couldn’t find it. You need to provide explicitly Firefox installed binary location to launch Firefox as below :-

from selenium import webdriver
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary

binary = FirefoxBinary('path/to/installed firefox binary')
browser = webdriver.Firefox(firefox_binary=binary)

https://github.com/mozilla/geckodriver/releases

For Windows:

Download the file from GitHub, extract it, and paste it in Python file. It worked for me.

https://github.com/mozilla/geckodriver/releases

For me, my path path is:

C:UsersMYUSERNAMEAppDataLocalProgramsPythonPython39
Respondent: Saurabh Gaur

Solution #2:

This solved it for me.

from selenium import webdriver
driver = webdriver.Firefox(executable_path=r'yourpathgeckodriver.exe')
driver.get('http://inventwithpython.com')
Respondent: Nesa

Solution #3:

This steps solved it for me on Ubuntu and Firefox 50.

  1. Download geckodriver

  2. Copy geckodriver to folder /usr/local/bin

You do not need to add:

firefox_capabilities = DesiredCapabilities.FIREFOX
firefox_capabilities['marionette'] = True
firefox_capabilities['binary'] = '/usr/bin/firefox'
browser = webdriver.Firefox(capabilities=firefox_capabilities)
Respondent: Andrea Perdicchia

Solution #4:

The answer by @saurabh solves the issue, but it doesn’t explain why Automate the Boring Stuff with Python doesn’t include those steps.

This is caused by the book being based on Selenium 2.x and the Firefox driver for that series does not need the Gecko driver. The Gecko interface to drive the browser was not available when Selenium was being developed.

The latest version in the Selenium 2.x series is 2.53.6 (see e.g. [these answers][2], for an easier view of the versions).

The [2.53.6 version page][3] doesn’t mention Gecko at all. But since version 3.0.2 the documentation [explicitly states][4] you need to install the Gecko driver.

If after an upgrade (or install on a new system), your software that worked fine before (or on your old system) doesn’t work anymore and you are in a hurry, pin the Selenium version in your virtualenv by doing

pip install selenium==2.53.6

but of course the long term solution for development is to setup a new virtualenv with the latest version of selenium, install the Gecko driver and test if everything still works as expected.

But the major version bump might introduce other API changes that are not covered by your book, so you might want to stick with the older Selenium, until you are confident enough that you can fix any discrepancies between the Selenium 2 and Selenium 3 API yourself.

Respondent: Anthon

Solution #5:

On macOS with Homebrew already installed you can simply run the Terminal command

$ brew install geckodriver

Because homebrew already did extend the PATH there’s no need to modify any startup scripts.

Respondent: roskakori

Solution #6:

To set up geckodriver for Selenium Python:

It needs to set the geckodriver path with FirefoxDriver as the below code:

self.driver = webdriver.Firefox(executable_path = 'D:Selenium_RiponAlWasimgeckodriver-v0.18.0-win64geckodriver.exe')

Download geckodriver for your suitable OS (from https://github.com/mozilla/geckodriver/releases) ? Extract it in a folder of your choice ? Set the path correctly as mentioned above.

I’m using Python 3.6.2 and Selenium WebDriver 3.4.3 on Windows 10.

Another way to set up geckodriver:

i) Simply paste the geckodriver.exe under /Python/Scripts/ (in my case the folder was: C:Python36Scripts)
ii) Now write the simple code as below:

self.driver = webdriver.Firefox()
Respondent: Ripon Al Wasim

Solution #7:

If you are using Anaconda, all you have to do is activate your virtual environment and then install geckodriver using the following command:

    conda install -c conda-forge geckodriver
Respondent: Rodolfo Alvarez

Solution #8:

I see the discussions still talk about the old way of setting up geckodriver by downloading the binary and configuring the path manually.

This can be done automatically using webdriver-manager

pip install webdriver-manager

Now the above code in the question will work simply with the below change,

from selenium import webdriver
from webdriver_manager.firefox import GeckoDriverManager

driver = webdriver.Firefox(executable_path=GeckoDriverManager().install())
Respondent: Navarasu

Solution #9:

Ubuntu 18.04+ and the newest release of geckodriver

This should also work for other *nix varieties as well.

export GV=v0.29.0
wget "https://github.com/mozilla/geckodriver/releases/download/$GV/geckodriver-$GV-linux64.tar.gz"
tar xvzf geckodriver-$GV-linux64.tar.gz
chmod +x geckodriver
sudo cp geckodriver /usr/local/bin/

For Mac update to:

geckodriver-$GV-macos.tar.gz
Respondent: jmunsch

Solution #10:

The easiest way for Windows!

Download the latest version of geckodriver from here. Add the geckodriver.exe file to the Python directory (or any other directory which already in PATH). This should solve the problem (it was tested on Windows 10).

Respondent: Jalles10

Solution #11:

Steps for Mac

The simple solution is to download GeckoDriver and add it to your system PATH. You can use either of the two approaches:

Short Method

  1. Download and unzip Geckodriver.

  2. Mention the path while initiating the driver:

     driver = webdriver.Firefox(executable_path='/your/path/to/geckodriver')
    

Long Method

  1. Download and unzip Geckodriver.

  2. Open .bash_profile. If you haven’t created it yet, you can do so using the command: touch ~/.bash_profile. Then open it using: open ~/.bash_profile

  3. Considering GeckoDriver file is present in your Downloads folder, you can add the following line(s) to the .bash_profile file:

     PATH="/Users/<your-name>/Downloads/geckodriver:$PATH"
     export PATH
    

By this you are appending the path to GeckoDriver to your System PATH. This tells the system where GeckoDriver is located when executing your Selenium scripts.

  1. Save the .bash_profile and force it to execute. This loads the values immediately without having to reboot. To do this you can run the following command:

source ~/.bash_profile

  1. That’s it. You are done! You can run the Python script now.

Solution #12:

Some additional input/clarification for future readers of this thread:

The following suffices as a resolution for Windows 7, Python 3.6, and Selenium 3.11:

dsalaj’s note for another answer for Unix is applicable to Windows as well; tinkering with the PATH environment variable at the Windows level and restart of the Windows system can be avoided.

(1) Download geckodriver (as described in this thread earlier) and place the (unzipped) geckdriver.exe at X:Folderofyourchoice

(2) Python code sample:

import os;
os.environ["PATH"] += os.pathsep + r'X:Folderofyourchoice';

from selenium import webdriver;
browser = webdriver.Firefox();
browser.get('http://localhost:8000')
assert 'Django' in browser.title

Notes:
(1) It may take about 10 seconds for the above code to open up the Firefox browser for the specified URL.
(2) The Python console would show the following error if there’s no server already running at the specified URL or serving a page with the title containing the string ‘Django’:
selenium.common.exceptions.WebDriverException: Message: Reached error page: about:neterror?e=connectionFailure&u=http%3A//localhost%3A8000/&c=UTF-8&f=regular&d=Firefox%20can%E2%80%9

Solution #13:

geckodriver is not installed by default.

$ geckodriver

Command 'geckodriver' not found, but it can be installed with:

sudo apt install firefox-geckodriver

$

The following command not only installs it, but it also puts it in the executable PATH.

sudo apt install firefox-geckodriver

The problem is solved with only a single step. I had exactly the same error as you and it was gone as soon as I installed it. Go ahead and give it a try.

$ which geckodriver
/usr/bin/geckodriver
$
$ geckodriver
1337    geckodriver    INFO    Listening on 127.0.0.1:4444

Respondent: Sabrina

Solution #14:

I’ve actually discovered you can use the latest geckodriver without putting it in the system path. Currently I’m using

https://github.com/mozilla/geckodriver/releases/download/v0.12.0/geckodriver-v0.12.0-win64.zip

Firefox 50.1.0

Python 3.5.2

Selenium 3.0.2

Windows 10

I’m running a VirtualEnv (which I manage using PyCharm, and I assume it uses Pip to install everything).

In the following code I can use a specific path for the geckodriver using the executable_path parameter (I discovered this by having a look in
Libsite-packagesseleniumwebdriverfirefoxwebdriver.py ). Note I have a suspicion that the order of parameter arguments when calling the webdriver is important, which is why the executable_path is last in my code (the second to last line off to the far right).

You may also notice I use a custom Firefox profile to get around the sec_error_unknown_issuer problem that you will run into if the site you’re testing has an untrusted certificate. See How to disable Firefox’s untrusted connection warning using Selenium?

After investigation it was found that the Marionette driver is incomplete and still in progress, and no amount of setting various capabilities or profile options for dismissing or setting certificates was going to work. So it was just easier to use a custom profile.

Anyway, here’s the code on how I got the geckodriver to work without being in the path:

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

firefox_capabilities = DesiredCapabilities.FIREFOX
firefox_capabilities['marionette'] = True

#you probably don't need the next 3 lines they don't seem to work anyway
firefox_capabilities['handleAlerts'] = True
firefox_capabilities['acceptSslCerts'] = True
firefox_capabilities['acceptInsecureCerts'] = True

# In the next line I'm using a specific Firefox profile because
# I wanted to get around the sec_error_unknown_issuer problems with the new Firefox and Marionette driver
# I create a Firefox profile where I had already made an exception for the site I'm testing
# see https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles#w_starting-the-profile-manager

ffProfilePath = 'D:WorkPyTestFrameworkFirefoxSeleniumProfile'
profile = webdriver.FirefoxProfile(profile_directory=ffProfilePath)
geckoPath = 'D:WorkPyTestFrameworkgeckodriver.exe'
browser = webdriver.Firefox(firefox_profile=profile, capabilities=firefox_capabilities, executable_path=geckoPath)
browser.get('http://stackoverflow.com')

Solution #15:

Consider installing a containerized Firefox:

docker pull selenium/standalone-firefox
docker run --rm -d -p 5555:4444 --shm-size=2g selenium/standalone-firefox

Connect using webdriver.Remote:

driver = webdriver.Remote('http://localhost:5555/wd/hub', DesiredCapabilities.FIREFOX)
driver.set_window_size(1280, 1024)
driver.get('https://toolbox.googleapps.com/apps/browserinfo/')
driver.save_screenshot('info.png')

Solution #16:

It’s really rather sad that none of the books published on Selenium/Python and most of the comments on this issue via Google do not clearly explain the pathing logic to set this up on Mac (everything is Windows!!!!). The YouTube videos all pickup at the “after” you’ve got the pathing setup (in my mind, the cheap way out!). So, for you wonderful Mac users, use the following to edit your Bash path files:

touch ~/.bash_profile; open ~/.bash_profile*

Then add a path something like this….

# Setting PATH for geckodriver
PATH=“/usr/bin/geckodriver:${PATH}”
export PATH

# Setting PATH for Selenium Firefox
PATH=“~/Users/yourNamePATH/VEnvPythonInterpreter/lib/python2.7/site-packages/selenium/webdriver/firefox/:${PATH}”
export PATH

# Setting PATH for executable on Firefox driver
PATH=“/Users/yournamePATH/VEnvPythonInterpreter/lib/python2.7/site-packages/selenium/webdriver/common/service.py:${PATH}”
export PATH*

This worked for me. My concern is when will the Selenium Windows community start playing the real game and include us Mac users into their arrogant club membership.

Solution #17:

I’m using Windows 10 and this worked for me:

  1. Download geckodriver from here. Download the right version for the computer you are using.
  2. Unzip the file you just downloaded and cut/copy the “.exe” file it contains
  3. Navigate to C:{your python root folder}. Mine was C:Python27. Paste the geckodriver.exe file in this folder.
  4. Restart your development environment.
  5. Try running the code again. It should work now.

Solution #18:

Selenium answers this question in their DESCRIPTION.rst file:

Drivers
=======

Selenium requires a driver to interface with the chosen browser. Firefox,
for example, requires geckodriver <https://github.com/mozilla/geckodriver/releases>_, which needs to be installed before the below examples can be run. Make sure it’s in your PATH, e. g., place it in /usr/bin or /usr/local/bin.

Failure to observe this step will give you an error `selenium.common.exceptions.WebDriverException: Message: ‘geckodriver’ executable needs to be in PATH.

Basically just download the geckodriver, unpack it and move the executable to your /usr/bin folder.

Respondent: Peter Graham

Solution #19:

For Windows users

Use the original code as it’s:

from selenium import webdriver
browser = webdriver.Firefox()
driver.get("https://www.google.com")

Then download the driver from: mozilla/geckodriver

Place it in a fixed path (permanently)… As an example, I put it in:

C:Python35

Then go to the environment variables of the system. In the grid of “System variables” look for the Path variable and add:

;C:Python35geckodriver

geckodriver, not geckodriver.exe.
