This example shows how to setup an environment running Rails 3 under 1.9.2 with a 'rails3' gem set. | |
∴ rvm update --head | |
# ((Open a new shell)) or do 'rvm reload' | |
# If you do not already have the ruby interpreter installed, install it: | |
∴ rvm install 1.9.2 | |
# Switch to 1.9.2-head and gemset rails3, create if it doesn't exist. | |
∴ rvm --create use 1.9.2@rails3 |
