Question

After going through the effort of finally purging distro ruby packages from my Ubuntu development sandbox to replace with the highly recommended rvm, I must be misunderstanding something fundamental:

I don’t want to have to change all the shebang lines in all my .rb source files from

#!/usr/bin/ruby

into /usr/local/rvm/bin/ruby nor anything version-specific.

My source files need to remain constant with their counterparts on the production servers using the system default ruby binaries (not rvm).

Any suggestions to keep universal code consistency? Should I be switching the shebangs, once and for evermore, to something like

#!/usr/bin/env ruby

or (despite what that link’s site says) is there some clean way for rvm to hook into /usr/bin/ruby assuming all conflicting .deb packages had been removed? Not to mention, how to get other .deb packages dependent on the presence of ruby+libs to recognize the non-distro ruby…but that might be a separate issue.

Answer 1

the only sane way to go is:

#!/usr/bin/env ruby

it will always use current selected ruby in the environment, not depending on any tool
