Composer could not find the config file

Question

I want to create a laravel project by composer. I try to run this:

composer create-project laravel/laravel c:/laravel --prefer-dist

There is an error which is:

  [InvalidArgumentException]
  Composer could not find the config file: C:\ProgramData\ComposerSetup\bin
  To initialize a project, please create a composer.json file as described in
   the http://getcomposer.org/ "Getting Started" section

The composer.json file is:

{
    "require": {
        "laravel/laravel": "4.2.0"
    }
}

I am using windows 8 and use cygwin. I also have a proxy on my computer so I set the path of HTTP_PROXY_REQUEST_FULLURI and HTTPS_PROXY_REQUEST_FULLURI to 0 and false

Any idea?

Answer 1

Delete the environment variable composer. And It will work.

Answer 2

I found the solution like this:

COMPOSER=composer.json composer create-project laravel/laravel c:/laravel --prefer-dist

and it works!
