How to force composer to reinstall a library?

Solution 1:

First execute composer clearcache

Then clear your vendors folder

rm -rf vendor/*

or better yet just remove the specific module which makes problems to avoid having to download all over again.

Solution 2:

You can use the --prefer-source flag for composer to checkout external packages with the VCS information (if any available). You can simply revert to the original state. Also if you issue the composer update command composer will detect any changes you made locally and ask if you want to discard them.

Your .gitignore file is related to your root project (ZF2 skeleton) and it prevents the vendor dir (where your third party libs are) from committing to your own VCS. The ignore file is unrelated to the git repo's of your vendors.

Solution 3:

I didn't want to delete all the packages in vendor/ directory, so here is how I did it:

rm -rf vendor/package-i-messed-up
composer install again

Solution 4:

What I did:

Deleted that particular library's folder
composer update --prefer-source vendor/library-name

It fetches the library again along with it's git repo

Solution 5:

Reinstall the dependencies. Remove the vendor folder (manually) or via rm command (if you are in the project folder, sure) on Linux before:

rm -rf vendor/

composer update -v
