Problem with upgrading rubygems via rvm

Question

Trying to updgrade RubyGems to version 1.8.10 via RVM and this error:

$ rvm rubygems latest
Removing old Rubygems files...
Installing rubygems-1.8.10 for ruby-1.9.2-p180 ...

When checking the log file (rubygems.install.log) this is generated from installation:

RubyGems 1.8.10 installed

Does anyone have an idea of ​​what could be wrong with the update? Have tried to remove rubygems via the RVM also, and then run the update again but no luck with it.

Update: Seems like rvm could not run Ruby 1.9.2.

$ rvm use 1.9.2 WARN: ruby ruby-1.9.2-p290 is not installed. To install do: 'rvm install ruby-1.9.2-p290' 

So after installing 1.9.2-p290 the installation of rubygems completed successfully.

$ rvm use 1.9.2
Using /Users/foo/.rvm/gems/ruby-1.9.2-p290

$ rvm rubygems latest

That worked for me.

I fixed it by removing this file .gemrc in root

cd ~
rm .gemrc
rvm rubygems latest
