    How to set /usr/bin/env ruby to an arbitrary ruby?

    When I run scripts with a shebang such as #!/usr/bin/env ruby I'd like to invoke a particular ruby. Right now, I haven't told /usr/bin/env where I installed ruby to and I would very much like to.

    What I'm doing with this:

    I'm working on a bash script and one of the many things it does is install rvm. But rvm is a really weird thing and so you can't use it from scripts to setup rubies. But you can install it from a script, and you can use it to install rubies from a script. From there, though, if I try to install a gem, I get an error that

    /usr/bin/env: ruby: No such file or directory

    Ughh... solved it

    export PATH=$PATH:`echo ~/.rvm/rubies/ruby-1.9.3-*/bin`
    I was specifying export PATH=$PATH:`echo ~/.rvm/rubies/ruby-1.9.3-*/bin/ruby` by typo. Oops =/
