Can I set Vim's 'embedded' ruby path?

Question

When I run:

:ruby print VERSION

in Vim, I get 1.8.7.

I have 1.9.3 installed and I'd like to use that instead. Is there a way to change it?

Would it use the same Gem paths?

I'm not talking about the !ruby command. I'm talking about the 'embedded' Ruby that's part of Vim.

Answer 1

Yes, but you'll have to recompile Vim. Vim will compile against whatever Ruby is first in your $PATH at compile time, so you should just be able to download the source and run:

./configure --enable-rubyinterp # + other options you want
make
make install

If you're on OS X using Homebrew, you may wish to just brew install vim or brew install macvim --override-system-vim.

You would have to recompile Vim to change the version. Just Google for something including vim "--enable-rubyinterp".

Beware that you need to recompile all of your native plugins that were compiled with the old ruby version.
