bootsnap `require': 无法加载此类文件 -- faraday/request/multipart (LoadError)

Question

Suddenly got this error when starting my rails server

bundle exec rails s

Here is the error message

         1: from /Users/michelleroos/.rbenv/versions/2.5.3/lib/ruby/gems/2.5.0/gems/bootsnap-1.11.1/lib/bootsnap/load_path_cache/core_ext/kernel_require.rb:15:in `require'

I'm not sure if it is something to do with my gem file. I Googled the error and tried the solutions proposed in other SO threads but nothing worked.

What I tried already:

• Basically everything in this thread

Answer 1

In my case I got this error after fixing an initial error regarding the Spring gem and then after fixing an error regarding Multipart post . After lot of trial and error I decided to undo all the fixes by doing a git reset --hard and then removing the spring and spring-watcher-listen gems from the Gemfile and then uninstalling these 2 gems via the bundle exec gem uninstall gemname command.

I then discovered a new error when trying to run rails s which was about MySQL . Finally after fixing those errors I was able to do a successful rails s . I then added back the 2 gems, ran bundle and had no errors afterwards.
