Hi,

I installed the rainbows gem and symlinked rainbows-2.0.1/bin/rainbows
to /usr/local/bin/rainbows
However, running rainbows gives: -bash: /usr/local/bin/rainbows:
/this/will/be/overwritten/or/wrapped/anyways/do/not/worry/ruby: bad
interpreter: No such file or directory

Any ideas what I should have done instead?

You shouldn't have had to make a symlink, if you used gems, then
RubyGems will have put a "rainbows" executable wrapper in the same
prefix as your other gems (probably same path as the "gem" command) that
loads and wraps the $GEM_HOME/gems/rainbows-2.0.1/bin/rainbows script...

In short, it works the same way as unicorn, mongrel, thin or any
other RubyGem that distributes executable scripts.

what platform are you on? you shouldn't have to link gem executable scripts anywhere for them to work.

when I install gems, the system creates a wrapper executable in an existing bin/ directory (/usr/bin/ on OSX, /var/lib/gems/1.9.1/bin/ on Debian Squeeze) that lets you force a version for the loaded gem and then loads the original executable script without launching a new interpreter - this ignores the supposed #! line in the gem's internal bin/rainbows, which is why that file says its #! will be overwritten or wrapped.

If installing rainbows didn't leave an executable script somewhere in your $PATH you might need to find where your local gem package is putting the wrappers and add that to your search path.

cheers

Russell

Ah! For me it's /usr/local/ruby-enterprise-1.8.7-2010.01/bin

That makes much more sense. Thanks!
