Backtrace 🐾

<<BACKTRACE IF RELEVANT>>

[RenWenshan]

I'd try gem install rubocop first and see what happens (make sure which ruby returns /Users/romario/.rvm/rubies/ruby-2.5.0/bin/ruby).

[rlopzc]

Did that, still not working @RenWenshan , thanks

[RenWenshan]

@romariolopezc maybe try "M-x rvm-use" followed up with selecting 2.5.0?

[rlopzc]

@wenshan just tried that, no success :/ On Mar 25, 2018 at 22:49, Wenshan <notifications@github.com> wrote: @romariolopezc <https://github.com/romariolopezc> maybe try "M-x rvm-use" followed up with selecting 2.5.0? — You are receiving this because you were mentioned.

I experience this without the use of rvm.

[vrinek]

Me too, not using rvm, on Ruby 2.6.0:

/Users/kostask/.gem/ruby/2.6.0/gems/rubocop-0.65.0/lib/rubocop/...

[jesusbv]

@romariolopezc maybe try "M-x rvm-use" followed up with selecting 2.5.5

It worked for me, installed rvm and run M-x rvm-use => fixed.
My message was a little bit different

Just updated to develop and ran into this issue while I was using rubocop without problem on master and from the terminal. Using rbenv, tried M-x rbenv-use 2.7.0 to no avail

EDIT:
Figured out my issue.
I migrated from rvm to rbenv a few months ago, and I thought nuking ~/.rvm would be enough to erase it.
Unfortunately, my ~/.spacemacs.env was littered with rvm-related variables which really confused the ruby layer when combined with rbenv.
Deleting ~/.spacemacs.env and letting Spacemacs regenerate it on next startup fixed it.
