Ruby Version and Ruby Environment Mismatch

Question

Im having some issues where my gems are being referenced from the incorrect directory for a specific version of Ruby. I have created an rvm gemset for ruby-1.8.7-p374, but installing gems puts them in the directory for ruby-1.9.3-p392.

$ rvm current

ruby-1.8.7-p374

$ gem environment

Answer 1

It is possible that your shell configuration for GEM_PATH / GEM_HOME is out of sync with PATH , to fix it simply run:

rvm use ruby-1.9.3-p392

OR:

rvm use ruby-1.8.7-p374
