Getting the following error message when trying to use rake?
undefined method `loaded_specs' for Gem:Module
Try updating RubyGems:
$ gem update --system
Getting the following error message when trying to update?
Installing RubyGems 1.3.2 ERROR: While executing gem ... (Errno::ENOMEM) Cannot allocate memory
You're out of RAM. To see how much memory you got left, issue the command:
$ free -m
And to see which process eats up most memory space:
$ ps -eo pmem,pcpu,rss,vsize,args | sort -k 1 -r -n | more
I temporarily shut down mysql and apache, that was just enough to be able to update RubyGems successfully.
