Switching back to ruby 2.6 after installing / using 2.7 - strange ruby errors

[joemsak]

When I try to switch back to asdf local ruby 2.6.5 after having been in 2.7.0 ruby no longer works. I've tried removing / re-adding the ruby plugin, I've tried updating asdf, and I've tried reinstalling 2.6.5, and nothing works, giving me a strange error I can't get any google results about

% asdf exec ruby -v
Traceback (most recent call last):

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false

(my .gemrc locks bundler to 1.17.3, for rails 4.2)

I have no idea what to do, the last time I got stuck like this was a week or so ago and I reinstalled my entire OS as a result (macOS Catalina)

Thanks for your time!

You are not alone. I have re-installed and uninstalled both rbenv and rvm in attempt to fix this issue without success. Getting the weird behavior below when using ruby 2.6.5 with ruby 2.7.0 installed:

(base) ➜  ~ rvm list
 * ruby-2.6.5 [ x86_64 ]
=> ruby-2.7.0 [ x86_64 ]

# => - current
# =* - current && default

any update on this ?

[coros-sanborn]

I'm having the same issue. I can no longer access my older ruby projects.

[rafaelcgs10]

Funny, I have the same problem but with rvm.

Edit:

unset RUBYOPT

solved for me, but my problem was with rvm.

[bhaskarshankarling]

Thank you @rafaelcgs10. I am also using rvm to install and manage different versions of ruby and I was also facing the above problem with ruby 2.7.0. I had set to export RUBYOPT='-W:no-deprecated -W:no-experimental' in bashrc to disables warnings from ruby as it was throwing lots of warnings when used with latest Rails 6 and commenting the RUBYOPT from bashrc solved the problem.

Weird thing with this is that, it happened with me twice and both the times it did not happen immediately after setting the RUBYOPT in bashrc but the problem starts appearing after the next restart of the system.

Can you guys help regarding what would be the right place to report this bug? should it be reported in rvm or ruby?

[danielsellergren]

Same issue with rbenv having 2.7.0 installed and then trying to use 2.6.5.

Running unset RUBYOPT worked for me.

[haroldofurtado]

Having the same problem here, any solution?

[datty258]

unset RUBYOPT

[ramonrails]

Funny, I have the same problem but with rvm.

Edit:

unset RUBYOPT

solved for me, but my problem was with rvm.

rbenv 1.1.2, ruby 2.6.6, 2.6.4, 2.6.0 (client projects with specific needs) working after unset RUBYOPT

Ah damn! I wish this had been the first result in Google? I ended up here by guessing after hours of trying to debug this issue! Sure enough, there was a RUBYOPT value set in zshrc on this old laptop. 🤦

I feel like ruby really could have helped me out here by mentioning that I had RUBYOPT set to "bleh" 😁

Ok, let's see if we can help some others:

Edit:

unset RUBYOPT

solved for me, but my problem was with rvm.

The solution fixed my issue also(with rbenv)

[Stratus3D]

Is there anything in asdf-ruby contributing to this problem? We use ruby-build for Ruby builds and don't set RUBYOPT anywhere in the code.

[jonaustin]

fwiw; even after removing the RUBYOPT export from zshrc, it still (somehow) persists without a full reboot of the system. i.e. env|grep RUBYOPT still has it even after removing from zshrc and starting a brand new shell/terminal (this is with asdf-vm on Arch Linux)

tl;dr -- if this is still happening even after removing RUBYOPT from your shell config, make sure to reboot.
