Could not open input file: composer.phar

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:\ProgramData\Composer\bin\composer.phar create-project yiisoft/yii2-app-advanced advanced 2.0.0-alpha

and it worked.

Use this :

php -r "readfile('https://getcomposer.org/installer');" | php

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

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 wamp\bin\php\php-<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
