Bundler claims to have installed my bundle, but can't find Rails or MySQL

Question

I'm logged in to my production server to try to manually dig into a problem I'm having with my Capistrano deployments.

Here's the line that Capistrano is running.

deploy@borges:/domains/myapp.com/releases/20140119013611$ env RBENV_ROOT="/home/deploy/.rbenv" PATH="/home/deploy/.rbenv/shims:/home/deploy/.rbenv/bin:$PATH" RBENV_VERSION="2.0.0-p353" /home/deploy/.rbenv/bin/rbenv exec bundle install --gemfile /domains/myapp.com/releases/20140119013611/Gemfile --path /domains/myapp.com/shared/bundle --deployment --without development test

Your bundle is complete!
Gems in the groups development and test were not installed.
It was installed into /domains/myapp.com/shared/bundle

Alternately, I can just run bundle install from that release directory and I get the same output. (Curiously, I get Your bundle is complete! in green when I just run bundle update but not when I run the longer line, though the text of the output seems identical.)

However, something is still not quite right about my bundle, because I can't get rails to work without invoking Bundler:

# rails c
The program 'rails' is currently not installed.  To run 'rails' please ask your administrator to install the package 'rails'

And when I try to run rails with Bundler, it complains that it can't locate MySQL:

# be rails c

The even stranger thing about the No such file or directory - /domains/myapp.com/shared/bundle/ruby/2.0.0/gems/mysql2-0.3.14/lib/mysql2/mysql2.so error is that I can tab-complete my way down that exact path to that exact file. So it's definitely not "missing."

Any ideas what's going on here? What am I missing?

Update: I have noticed that bundle install --deployment seems to do something else altogether, with Installing rake etc., rather than Using rake. Now I can run be rails c and be rake db:migrate and they all work. So that's great. But still my cap deploy is failing, because it's using the first command listed above. How can I address the root cause?

Update 2: Attempting to use bundle exec cap deploy from my local machine results in similar output. Here's the full output:

@ansh0l Thanks for the link. Looks like that user needed to install something nodejs-specific, so I'm not sure what the ruby/rails equivalent could be, in my case... — isthmuses, Jan 20 '14 at 00:57

First of all you're setting quite many environment variables when running bundle install, but not setting any of them when running rails c. So these two commands run in different environments and this can cause problems.

Now to the questions: try running cap through bundle exec too.

bundle exec cap deploy

Thanks for the reply! I've updated the question with my attempts to run `bundle exec cap deploy` from my local machine (the `bundle install` commands were being run ssh'ed into the deployment server as the deploy user). Unfortunately it looks like the errors are quite similar to before. Any ideas what might be up? – isthmuses Jan 20 '14 at 00:53
