I got the same error. Did you find out why @KamilLelonek ?

[KamilLelonek]

I threw away chruby.

[grzuy]

Same issue here. Anyone found the reason?

Anyone found a solution?

Also getting this. Logging into the server and running chruby-exec works fine...

I had to set :pty, true (which is not a good idea). Think it's a chruby-exec problem.

[mxhold]

A quick fix to this for those that are having this issue is to add the /etc/profile.d/chruby.sh script as the chruby README suggests:

if [ -n "$BASH_VERSION" ] || [ -n "$ZSH_VERSION" ]; then
  source /usr/local/share/chruby/chruby.sh
fi

This works because if you run chruby-exec from a non-interactive shell (which is what Capistrano does by default unless you set :pty, true) then it will run the sub-shell as a non-interactive, login shell. This means ~/.bashrc will not get loaded but /etc/profile.d will.

There is a pull request for fixing this at postmodern/chruby#250 but it looks like it needs to be updated.

FWIW we documented this behaviour: http://capistranorb.com/documentation/faq/why-does-something-work-in-my-ssh-session-but-not-in-capistrano/#which-shell-startup-files-do-get-loaded?

[fnordfish]

Thanks for the pointers!

For sure that graphic is one that starts only to make sense once you actually understand what it tells you, but it won't teach you anything :-D

I ran into similar issue, but sudo appears to work fine

› /bin/bash -c '/usr/local/bin/chruby-exec 2.2.3 -- gem -v'
chruby-exec: RUBY and COMMAND required
› /bin/bash -c 'sudo /usr/local/bin/chruby-exec 2.2.3 -- gem -v'
2.4.5.1

So, I just ran into this bug and researched it all the way down to the root cause.

The script chruby-exec first does a source /usr/local/share/chruby/chruby.sh then does some logic and finally runs exec $SHELL ... chruby ....

This can not work. exec will not carry shell functions to the new fork. This behaviour was changed after shell-shock. Neither the Ubtunu-14.04 nor the Gentoo ~amd64 I have here will carry the chruby shell function in the newly forked shell after exec. So to make it clear, the exec statement clears all the shell functions that chruby-exec previously sourced to function properly.

I can not explain why some users above describe to only see this when using sudo. Perhaps some quirky work-around of the individual distro they are using? Perhaps not using Bash?

source <some-shell-functions>
exec $SHELL -c 'binary-using-shell-functions-above'

... will never work.

[baccenfutter]

Proposed fix: remove the exec.

Why exec in the first place?
Why not just $SHELL -c "chruby ..."?
