Question

After I installed a version of ruby with rvm, I noticed that some minor configuration issue on installation process. So I wanted to try to install with another configuration options, but I don’t want to spoil the installed ruby at all.
So I just to attempt to backup the installed ruby before rvm reinstall.

(cd .rvm/rubies && mv ruby-1.9.3-p194 ruby-1.9.3-p194.org)

In my case, reinstallation fixed the issue, I didn’t rollback ruby. So, I don’t know this can work.
Are there any clean or correct way? Just for future references.

Answer 1

you can install named rubies:

rvm install 1.9.3-test1 [options]

and after it worked set it as default:

rvm use 1.9.3-test1 --default

or reinstall the original 1.9.3, named rubies are useful especially for testing compilation flags or patched rubies:

rvm install 1.9.3-performance --patch falcon
