Question

[Solved] using pip3: module “importlib._bootstrap” has no attribute “SourceFileLoader”

I have installed pip for python 3.6 on Ubuntu 14. After I run

sudo apt-get install python3-pip

to install pip3, it works very well. However, after installation, when I am trying to run

pip3 install packagename

to install a new package, something strange occurs:

File "/usr/lib/python3/dist-packages/pkg_resources.py", line 1479, in <module>
 register_loader-type(importlib_bootstrap.SourceFileLoader, DefaultProvider)
AttributeError: module "importlib._bootstrap" has no attribute "SourceFileLoader"

It seems that I did nothing wrong, and I really cannot figure out the reason.

Solution #1:

Faced the same problem. I think this is because python3.6 and pip3 were installed from different sources.
I suggest using python’s inbuilt facility to install pip i.e

python3 -m ensurepip --upgrade

This should install pip3 and pip3.x where x in python3.x.
Same works for python2 also.

I can’t edit my existing answer, so I had to add another one:

This worked for me:

sudo pip install python-dotenv

when update python3.4 to python3.6 on ubuntu 14.04. The following solved me:

wget https://bootstrap.pypa.io/ez_setup.py -O - | python3

Solution #6:

that’s because you are using an old version of setuptools, check up this issue.

Solution #7:

If you face this issue in anaconda environment, simply upgrade setuptools using the following:

conda install -c conda-forge setuptools

Solution #8:

Respondent: Tom Kruise

Solution #9:

pip install setuptools --upgrade

This command fixed my problem

Solution #10:

I am facing the same problem, which is solved by downloading the source files of the setuptools and installing the module manually.

The setuptools can be downloaded here:

https://pypi.org/project/setuptools/

After downloading, unzip the package first, then cd to the directory and run

python setup.py install --user

Solution #11:

For me the error happened while trying to create a virtual env with python 3.8:

sudo virtualenv venv -ppython3.8

And after trying all the answers here, finally the problem solved by installing the new version of virtualenv (20.0.7):

sudo pip3 install virtualenv
Respondent: Alex Jolig

Solution #12:

I had faced the same issue on Ubuntu 19.10 and now I upgraded to Ubuntu 20.04 and faced the issue again. This issue is due to broken pip3. So whenever you enter pip3 and hit enter it will show the same error. So instead of using “pip3 uninstall setuptools” use the below code

python3 -m pip uninstall setuptools

It resolved my issue 3rd time

Solution #13:

I encountered this error message triggered by a slightly different situation which I’ll mention here for anyone who finds this.

This same error also occurs when installing the distribute Python package (which is currently just a compatibility layer in front of setuptools) in Python 3.6 or newer.

In my specific situation I discovered this as I was using pyzmail which has been somewhat abandoned and depends on distribute.

Solution #14:

I had the same error whatever I asked to pip. I gave a look to this page: https://packaging.python.org/tutorials/installing-packages/

That line is the one that solved my problem:

python3 -m pip install --upgrade pip setuptools wheel

Solution #15:

I had the same issue when I tried to install the Slate package in Windows 10, Python 3.7.4 version:

AttributeError: module ‘importlib._bootstrap’ has no attribute ‘SourceFileLoader’

The instruction that generated the error:

C:WINDOWSsystem32>python -m pip install slate

The instruction that worked:

C:WINDOWSsystem32>python -m pip install https://github.com/timClicks/slate/archive/master.zip
Respondent: Mario Aldana

Solution #16:

Traceback (most recent call last):
File "/usr/bin/pipenv", line 6, in <module>
from pkg_resources import load_entry_point
File "/home/myuser/.local/lib/python3.7/site-packages/pkg_resources.py", line 
1479, in <module>

Mine looked pretty similar, but for some reason I had a python installation in my home directory .local folder.

I did some of the other answers in this thread to ensure I had good local copy of python, then did:

rm -rf ~/.local

I had the same problem with my cloud computer. If all above didn’t work for you don’t worry. Here’s how I resolved it:

  1. Download the pip file (pip-version.tar.gz) from:
https://pypi.org/project/pip/#files

For cloud, use this

curl https://files.pythonhosted.org/packages/8e/76/66066b7bc71817238924c7e4b448abdb17eb0c92d645769c223f9ace478f/pip-20.0.2.tar.gz --output pip.tar.gz
  1. Extract the content of the file and cd into the directory.
  2. Run the following in the directory
python3 setup.py install --user

You should have pip3 working without errors.

Solution #18:

just go inside the /usr/lib/python3/dist-packages/ first copy setuptools file somewhere and then delete the setuptools everything will be okay for deleting you can use

sudo rm -r setuptools

for copying

sudo cp -r setuptools /...Desktop/

after that if it gives errors just

sudo pip3 install setuptools==3.8.1

download again

Respondent: Dev Ran

Solution #19:

This is For Python 2

curl the package

curl "https://bootstrap.pypa.io/get-pip.py" -o "get-pip.py"

And do python get-pip.py

This is Important use command pip2 not pip
