It’s not your application, it’s the environment. Both the PostgreSQL
and
MySQL gems have portions written in C that must be compiled locally on
each
machine. If it can’t complete the compile, the gem doesn’t install.
That
is what’s happening on your server. The code requires a C extension
that
your system is not giving it access to.

It appears that you’re running jruby (ruby running in a java virtual
machine) and on Windows. I can’t help you with either one, sorry, but
that’s the issue.

It looks like you’ve installed jruby, which requires different gems for
some things. It doesn’t sound like you wanted this at all, so you’ve
either
got to

  • remove jruby
  • change your PATH environment variable so that it doesn’t appear ahead
    of
    ‘normal’ ruby
  • use something like uru ( https://bitbucket.org/jonforums/uru/ ) to
    manage
    multiple rubies

It is right; you are running JRuby and not ruby; If it’s the case, you
should install all the needed gems by prefixing it as follows:

jruby -S bundle install

If not, I had the same problem on a Windows box, i.e. JRuby had some
priorities on the Ruby installation. The only way to fix it was to
uninstall JRuby completely and everything came back to the normal.
