rubyruby-install

How does ruby-install work?

After installation of multiple rubies by ruby-install, how to use a specific installation of ruby? Should a ruby be accessed by absolute path, or depends on some environment path like rvm?

Solution

  • You can use postmodern's chruby to change the current Ruby:

    chruby 1.9
chruby
 * ruby-1.9.3-p429
   ruby-2.0.0-p195

    It also supports auto-switching based on a .ruby-version file.
