RVM and OSX Lion - RVM 'forgets' gemsets o

问题:

I never seemed to have this problem while doing Rails work in Linux, but since changing to OSX everytime I reboot my machine, RVM loses its list of gemsets, but they aren't actually gone.

For example, I have several gemsets already made, and I restart my computer.

I run the following command:

$ rvm gemset list

gemsets for system (found in /Users/evan/.rvm/gems/system)
*

This of course causes havoc when I run rails s to start up my server.

The only way I've managed to get the gemsets back is to create a dummy gemset:

$ rvm --create 1.9.2@blahblah
$ rvm gemset list

gemsets for ruby-1.9.2-p290 (found in /Users/evan/.rvm/gems/ruby-1.9.2-p290)
asdasdads
=> blahblah
global
rails3.1
rails31
test
test3
test6
whymvc

This shows all of the gemsets I have created (and need). At this point I change the gemset back to the one I want:

$ rvm gemset use rails3.1
Using /Users/evan/.rvm/gems/ruby-1.9.2-p290 with gemset rails3.1

At this point I'm back where I need to be to develop functionally until the next reboot.

I believe I followed the directions correctly at the RVM site, and my .bash_profile looks like so:

[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function

My question is this:

How can I configure RVM to 'remember' the gemsets I have created without creating/deleting dummy ones?

Edit #1 - rvm info output

Running rvm info produces the following output:

$ rvm info

回答1:

It appears that your default RVM ruby is not set.

Try running this:

rvm use --default --create 1.9.2@rails3.1

and then rebooting.

If your gemset already exists, you can omit the --create.

rvm use --default 1.9.2@rails3.1
