Solution #1:

Use this :

php -r "readfile('');" | php

This will install composer to the current directory so that you can use php composer.phar

Solution #2:

The composer.phar install is not working but without .phar this is working.

We need to enable the openssl module in php before installing the zendframe work.

We have to uncomment the line ;extension=php_openssl.dll from php.ini file.

composer use different php.ini file which is located at the wampbinphpphp-<version number>php.ini

After enabling the openssl we need to restart the server.

The execute the following comments.

I can install successfully using these commands –

composer self-update
composer install --prefer-dist

I was trying to install YII 2.0

php composer.phar create-project yiisoft/yii2-app-advanced advanced 2.0.0-alpha

I got the same error:

Could not open input file: composer.phar

Then i gave the full path of .phar like this:

php C:ProgramDataComposerbincomposer.phar create-project yiisoft/yii2-app-advanced advanced 2.0.0-alpha

and it worked.

I am using Windows 7, and I got the same problem as yours while using Composer via cmd.

The problem is solved when I use

php C:ProgramDataComposerSetupbincomposer.phar create-project slim/slim-skeleton

instead of

php composer.phar create-project slim/slim-skeleton

Hope this is useful for people who got the same problem.

Solution #5:

First try this: dont use the php composer.phar [parameters] simply use composer [parameters] if this doesn’t work for you than try the rest. Hope it helps.

Solution #6:

Initially, I was running php composer.phar self-update and got the same error message.

As a resolve, you should use composer command directly after install it.From the command prompt, just type composer and press enter.

If composer is installed correctly then you should able to see a lot of suggestion and command list from composer.

If you are up to this point then you should able to run composer self-update directly.

Question already answered by the OP, but I am posting this answer for anyone having similar problem, retting to

Could not input open file: composer.phar

error message.

Simply go to your project directory/folder and do a

composer update

Assuming this is where you have your web application:


change directory to it, and then run composer update.

I have fixed the same issue with below steps

  1. Open project directory Using Terminal (which you are using i.e. mintty )
  2. Now install composer within this directory as per given directions on

php -r “copy(‘‘, ‘composer-setup.php’);”

php -r “if (hash_file(‘SHA384’, ‘composer-setup.php’) === ‘the-provided-hash-code’) { echo ‘Installer verified’; } else { echo ‘Installer corrupt’; unlink(‘composer-setup.php’); } echo PHP_EOL;”

php composer-setup.php
php -r “unlink(‘composer-setup.php’);”

  1. Now run your command.

Everything is working fine now because the composer.phar file is available within the current project directory.

This is how it worked for me:

  • Make sure composer is installed without no errors.

  • Open “System Properties” on windows and go to the “Advanced” tab. (You can just press the windows button on your keyboard and type in “Edit the system environment variables`

  • “Environment variables”

  • Under “System variables” Edit “PATH”

  • Click on “New”.

  • Type in: C:ProgramDataComposerSetupbincomposer.phar

  • Close all folders & CMDs + restart you WAMP server.

  • Go to whatever directory you want to install a package in and type in

    composer.phar create-project slim/slim-skeleton

for example.

curl -sS | php

Solution #12:

Instead of

php composer.phar create-project --repository-url="" zendframework/skeleton-application path/to/install


php composer.phar create-project --repository-url="" zendframework/skeleton-application path/to/install

Just add https instead of http in the URL. Though it’s not a permanent solution, it does work.

Solution #13:

Another solution could be.. find the location of composer.phar file in your computer. If composer is installed successfully then it can be found in the installed directory.

Copy that location & instead of composer.phar in the command line, put the entire path there.

It also worked for me!

Respondent: user1052478

Solution #14:

If you go through the documentation, they have mentioned to use php composer.phar

Don’t use php composer.phar
only give composer

Command: composer self-update

It will work.

Solution #15:

I had the same issue when trying to use php composer install in a local directory on my Apache server for a laravel project I cloned from Github. My problem was I had already setup composer globally on my Ubuntu 18 machine.
Adding sudo instead of php started the install of a whole slew of packages listed in the json.lock file i.e. sudo composer install.
