ruby - How do I undo a gem install that messed up my Rails app? -

-

I have set up a gem to make my URL insensitive, but I see many broken links. Instead of going through and trying to fix them, I did not just set what I did.

If I run Uninstall gemname , then how will it deliver my railway app first?

You have to remove the gem from your Gemfile . Check your Gemfile.lock and see also the gem dependencies.

Of course, if you refer to the gem anywhere in your app, then you have to remove those references too.

I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge.
