LoadError: cannot load such file -- i18n/core_ext/hash

Question

I am working on multiple projects, when I switch from one project to another, compile the assets using:

➜ rails assets:precompile

Ruby: 2.7.5 Rails: 6.0

What I get is:

(See full trace by running task with --trace)

The problem seems to be of the i18n gem. I have even tried updating the bundler. But still getting this issue.

Even running the full trace doesn't gives me anything.

The i18n gem used is -> i18n (>= 0.7, < 2)

The chewy gem seems to be a problem

Answer 1

So got it fixed by cleaning all the global and local gems by using: gem uninstall -aIx

Created gemsets for each project and separate gems for each project. Bundle install all the gems.

The problem here was some gems were conflicting. Even on removing the gems, it wasn't being removed completely.

I hope this helps!
