I have an error while installing Ruby 1.9.3 through rvm.

rvm install 1.9.3-p0

Before that I had successful installations of new ruby versions. I found in google such errors, but no answers of this issue. And rails server can't start.

Answer 1

I had to upgrade RVM.

rvm get head
rvm reload
rvm install 1.9.3-p194
rvm use 1.9.3

If 1.9.3-p194 isn't the latest version (as of 06/07/2012), go to Ruby site to find out what is.

Answer 2

I don't understand why after using gem update --system to update to RubyGems 1.8.11, the same installer error hits me and it still looks in $RVM_HOME/src/rubygems-1.6.2/

UPDATE 1: I hadn't tried rvm get latest for some time. So I tried that to alleviate my problems. This is giving me a Permission denied because it is trying to run a script under /tmp . In my /etc/fstab , /tmp is mounted as noexec . When I get this resolved, I'll see if installing Ruby 1.9.3 works any better.

UPDATE 2: Issuing mount -o remount,exec /tmp let me finally do the Ruby 1.9.3 install.
