If you followed instructions like these:

$ curl -sS https://getcomposer.org/installer | php $ mv composer.phar /usr/local/bin/composer 

$ php composer.phar update friendsofsymfony/elastica-bundle 

$ composer update friendsofsymfony/elastica-bundle

The thing to remember is that if you installed it correctly (on Windows) and added it to your environment's PATH variable then you do not need to type php composer.phar and use composer instead.

After installing, make sure your PATH variable points to the directory where composer.phar is stored. This is usually C:\ProgramData\ComposerSetup\bin (ProgramData might be a hidden directory). It goes without saying, but also be sure that the PHP executable is also in your PATH variable.

composer install 

php composer.phar install

Thank you! That is not mentioned in the "basic usage" section in the Composer docs.. getcomposer.org/doc/01-basic-usage.md#installing-dependencies

It's been over two years since this answer, and the docs still haven't been updated, so I had the same problem. Thanks!

1，情景描述：在命令行窗口写入php artisan make:model Models\MenuModel用于创建模型时，出现此错误（Could not open input file: artisan）。 2，首先 artisan 是 Laravel 项目下的指令文件，在Laravel 项目的根目录下可以看到artisan文件。 所以首先要建立 Laravel 项目。 如果已经建立项目需要cd.

I had this issue while trying to setup composer globally. I ended up adding alias composer="php C:\\\\Users\\\\MyUsername\\\\bin\\\\composer.phar" to my .bashrc file. Ugly, but worked.
