Rails, gems, require, zsh and an error message! I can't load my app because of an issue related to “require”

Question

So, I tried to repair something that was not working related to my ZSH file, which I managed to do, but ended up breaking some other stuff apparently:/ Anyway I am trying to run my app locally (actually all my apps run into the exact same problem) and it doesn't launch. I get a long list of script in the terminal which looks like this:

    122: from /home/olivier/code/OGsoundFX/rails-mister-cocktail/bin/spring:15:in `<top (required)>'
    121: from /home/olivier/.rbenv/versions/2.6.5/lib/ruby/2.6.0/rubygems/core_ext/kernel_require.rb:54:in `require'

I am not an expert, far from it, and I am a bit lost. It looks like this has something to do with "require". Everything was working this morning before I fixed the other issue, and broke this. Any idea? Thanks!

Answer 1

OK I solved it, I just needed to 'bundle update' for some reason. I had tried 'bundle install' several times, because the problem did seem related to gems, but I didn't think of updating the gems.
