I've discovered, if developing any Composer scripts, when running
composer run-script [script-name], those scripts will use libraries bundled
in composer.phar instead of the vendor directory. This means you might get
out-of-date libraries and unexpected errors.
I have put together this simple example to illustrate this issue.
Here is how to reproduce:
git clone https://github.com/ramsey/composer-scripts-issue.git
cd composer-scripts-issue
Now, follow the instructions here to download composer.phar:
https://getcomposer.org/download/
./composer.phar install
./composer.phar run-script foo
With Composer version 1.10.6 (the latest version), you should see the following error output:
> Foo\Foo::run
PHP Fatal error: Uncaught Error: Call to undefined method Symfony\Component\Finder\Finder::ignoreVCSIgnored() in /.../composer-scripts-issue/Foo.php:17

If running composer from ./vendor/bin/composer, the script executes as
expected:
$ ./vendor/bin/composer run-script foo
> Foo\Foo::run
README.md
.gitignore
Foo.php
composer.json
