Composer revert packages

Question

I am building a new app in Symfony 2.1. I am using a lot of bundles pulled in using composer. A lot of these bundles have problems with this latest version of Symfony and I am having to go into the /vendor folder to identify the issues.

This means that I am changing the vendor files directly - purely for testing purposes. (When we have fixed a bundle we branch and submit appropriate pull request).

What I want to know is if there is some command like composer.phar revert which would undo any changes made to the vendor folder (like a git checkout). At the moment if I run a composer update or installit does not do this.

Thanks

Answer 1

composer install, if you have kept your composer.lock file, will revert all your vendors to the previously installed state.

Answer 2

 cd /my/project/location/

 rm -rf vendor/my_vendor_to_rollBack

 composer install

Answer 3

Add discard-changes to your composer.json file:

{
    "config": {
        "discard-changes": true
    }
}

Make sure you are using the latest version of Composer.

Answer 4

composer reinstall "*" removes and installs again all packages in vendor directory.

Answer 5

If you used composer update your composer.lock has changed to. So I make a little trick. Revert composer.lock by git and then run composer install. It'll remove newest packages and download the previous.

Answer 6

As far as I can tell, none of the answers above work except in relation to versions. I you change an installed version, you can revert to a previous version.

If you just delete or change a file, though, the change will show up in composer status -v, but there's no way to revert (even with "discard-changes":true) except by removing and then re-requiring the package.
