GemNotFoundException when not using default ruby as specified by rvm

[jared-thoughtbot]

Problem

When using rvm and trying to run overmind start it fails with Could not find 'bundler' (1.17.3) required by your /home/jaredt/projects/maitre-d/Gemfile.lock. (Gem::GemNotFoundException).

I seem to have narrowed this down to when using rvm and having the necessary ruby version installed and in use, but it not being the default rvm ruby.

Steps to reproduce

• Install rvm
• Install 2 ruby versions eg. 2.6.9 and 2.7.5
• Set one of the versions to default eg. rvm --default use 2.7.5
• Open application that uses the non-default version (eg. 2.6.9)
• Confirm the ruby version rvm is using is correct ruby -v and which ruby
• Confirm you can run the app directly eg. rails server
• Try overmind start

Notes

• Notice that it's using a different ruby version to what was confirmed above
• Use rvm list to confirm the other ruby version is installed and it's the default
• Try setting the application ruby version to be rvm's default eg. rvm --default use 2.6.9
• Retry overmind start
• It works! :)

Having similar issue. Getting error when running overmind start

Your Ruby version is 3.1.2, but your Gemfile specified 2.7.4

while having the current version pointed to 2.7.4

Seems like overmind use default instead of the current version of ruby.

Changing rvm default version to the needed version resolves the problem. @jared-thoughtbot, thanks for the suggested workaround.

Sorry, can't reproduce this :( Here's my shell output:

$ rvm list
=> ruby-2.7.6 [ arm64 ]
 * ruby-3.1.2 [ arm64 ]

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

$ ruby -v
ruby 2.7.6p219 (2022-04-12 revision c9c2245c0a) [arm64-darwin21]

$ which ruby
/Users/darthsim/.rvm/rubies/ruby-2.7.6/bin/ruby

$ ./overmind s -f Procfile.test
system     | Tmux socket name: overmind-overmind-bNgYagaY6ln9AuE5FxSDy
system     | Tmux session ID: overmind

As you can see, the current Ruby version differs from the default one yet Overmind uses the current version as expected.

On a very basic level, Overmind doesn't do anything fancy but run tmux with commands from the Procfile. You can emulate the same behavior without Overmind involved:

1. Create a test script: echo -e "#\!/bin/sh\nruby -v\nwhich ruby\nsleep 10" > ruby-test.sh
2. Make it executable: chmod +x ruby-test.sh
3. Run a new tmux server with it: tmux -L rubytest new ./ruby-test.sh

If it shows the wrong version too then Overmind is not a cause and you need to check your RVM installation.

Thanks for taking the time to investigate this!

I can confirm I'm seeing the wrong version when testing using your simplified script.

I am using fish shell so maybe there's something in the rvm config that's not right. I'll close this for now. Cheers!

@jared-thoughtbot I also have this issue on the fish shell. Probably something with fish configs 🤔
