Capistrano, Rbenv, bundle: command not found

After running

cap production deploy:restart

 
Our remote Puma log would show the following:

-su: bundle: command not found

 
However, this was an active production server, so the bundler gem existed. After logging in and attempting to run a simple command, such as:

bundle exec rails console

 
The console would output the following:

The program 'bundle' is currently not installed. You can install it by typing:
sudo apt-get install bundler

 
So, we looked at the PATH var to ensure RBENV was properly configured

printenv PATH

 
And it was.

If this is your problem (there should be rbenv paths specified here), then edit your ~/.bashrc or ~/.profile or whatever you’re using and add the following lines at the bottom:

export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"
export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"

 
This will most likely solve the problem you’re noticing.

However, in our case, this was not the issue. RBENV was properly configured, the environment variables were set, and bundler was definitely installed. Next, we figured we’d run

rbenv rehash

 
Just in case something went awry on that front, but we encountered this error:

rbenv: cannot rehash: /home/deployer/.rbenv/shims/.rbenv-shim exists


 
So, we're getting somewhere. This file only exists to avoid colliding rehashes, however, I knew no other rehash's were in progress, so this file must have not be cleaned out during the last rehash for some reason, so we ran:

rm ~/.rbenv/shims/.rbenv-shim

 
And re-ran

rbenv rehash

 
And everything went back to normal.
