Why can't I install Rails on Lion using RVM?

Question

I\'m running into issues trying to install Rails on OS X Lion using RVM.

So far, I have done the following:

1. Installed Mac OS X Lion Version 10.7 (Build

Answer 1

I have same problem only for arch x86_64, when I comment line in my ~/.rvmrc

rvm_archflags="-arch x86_64"

Open a new terminal and tried to install ruby-1.8.7 again

rvm install 1.8.7

It was successful.

Answer 2

If you're using RVM in a development workflow, I added a fix in an .rvmrc file for OS X Lion.
