Test if package can be installed against current lockfile + vendor

[damienwebdev]

I'm trying to write a fast "package installation" checker with composer and I'm wondering if there's a way to check whether a local package can be installed within another project "quickly".

Currently, in the dependent project I'm doing:

composer config repositories.local path path/to/package
composer require my-package "@dev"

Which works, but appears to trigger network requests (which I'm trying to avoid). Is something like this possible?

You could try to reduce the steps/narrow it down a bit more I guess:

composer config repositories.local path path/to/package
composer require my-package "@dev" --no-update
composer update my-package --dry-run
composer config repositories.local --unset

This will still do some network, but it should be less.

Awesome, thanks @Seldaek
