rvm can no longer install 1.8.7-p352 on Mac OS X Mountain Lion

Question

I upgraded rvm to 1.15.8, then went back down to 1.15.7 after having some problems in zsh. After downgrading, my Ruby 1.9+ versions went back in fine, but 1.8.7 won\'t install a

Answer 1

I think I ended up with two similar questions on sf here. My main problem was that the tcl.h include file on Mountain Lion (location: /usr/include/tcl.h symlinked) could not resolve an internal reference it had to "X11/Xlib.h". I thought that installing tcl and tk through homebrew would fix the problem by generating a path to Xlib.h that could be resolved. So I ran:

brew install tcl

and:

brew install tk

and:

rvm remove 1.8.7-p352
rvm install 1.8.7-p352

and it worked. But Michal's answer above would have worked just as well I think. This answer will serve to help people build it that need tcl and tk.

Answer 2

it is problem in detecting tcl/tk by ruby 1.8.7, the solution is to disable it:

rvm reinstall 1.8.7 --without-tcl --without-tk

the other solution when tcl/tk is needed: https://stackoverflow.com/a/11666019/497756
