Running Composer returns: "Could not open input file: composer.phar"

Question

I am new to symfony2 and reading symblog. In third chapter while trying with data-fixtures I tried the command:

php composer.phar update

but I got the error:

Could not open input file: composer.phar

So I googled a little and tried

php composer.phar install

but still getting the same error. So please guide how to deal with this composer to install new extentions or bundles like data-fixtures in symfony2 using wamp.

Answer 1

If you followed instructions like these:

https://getcomposer.org/doc/00-intro.md

Which tell you to do the following:

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

Then it's likely that you, like me, ran those commands and didn't read the next part of the page telling you to stop referring to composer.phar by its full name and abbreviate it as an executable (that you just renamed with the mv command). So this:

$ php composer.phar update friendsofsymfony/elastica-bundle

Becomes this:

$ composer update friendsofsymfony/elastica-bundle
