Ruby 1.9.2 not installing on OSX?

问题

1. I've got Xcode 3.2.1
2. I've installed Git and RVM
3. I've installed Ruby 1.9.2, it's installed 100%

4. I run ruby -v but instead of seeing

   ruby 1.9.2p0 (2010-08-18 revision 29036) [x86_64-darwin10.4.0]
   

   I see

   ruby 1.8.7 (2009-06-12 patchlevel 174) [universal-darwin10.0]
   

I don't see what I could be going wrong

回答1:

Try

rvm 1.9.2

Or

rvm --default 1.9.2

It is possible to use a .rvmrc to do that for the directory you cd into as well.

回答2:

Have you selected the version of ruby you want to use with rvm? As in this? Note the "rvm 1.9.2" line hidden away after the rvm and ruby installs.

回答3:

Type in 'rvm 1.9.2' and then type 'ruby -v'... did you do that? It looks like the Ruby 1.8.7 on your machine is the one included with OS X.
