Question

Attempting to use RVM on a Mac OS X 10.5.8.

> rvm install ruby-1.8.7-p334
ERROR: 
You passed the --clang option and clang is not in your path. 
Please try again or do not use --clang.

I have little idea what this error is about; looking in the RVM script leads nowhere. No luck on google finding this error string. 1.8.7 is in “rvm list known”.

Anyone seen this before?

Answer 1

I believe the problem is this commit, specifically the changes to .rvm/scripts/env.

Editing .rvm/scripts/manage is one way to fix the problem (see flitzwald’s answer for another way to do it):

  20 __rvm_check_for_clang()
  21 {
  22   if [[ "${rvm_clang_flag}" -eq 1 ]] && ! command -v clang >/dev/null ; then  
  23     rvm_error "\nYou passed the --clang option and clang is not in your path. \nPlease try again or do not use --clang.\n"
  24     return 1
  25   fi
  26 }

($rvm_clang_flag is set to 1 when you call for it in .rvm/scripts/cli. The error is being falsely tripped now because the flag’s default settings and the test for the flag don’t match up.)

Edit: Just a follow-up note. It was a bug; it’s been fixed. If you come by here via Google, rvm get head && rvm reload and all should be well again.
