You want to start a new Rails app. But you also want to start a new RVM gemset for the app so you can start with the latest Rails and gems. In this code snippet I show how I start off an up-to-date Rails project in a clean gemset.
Creating a new Rails app
# create and use the new RVM gemset $ rvm use --create 1.9.3@awesome_rails_project # install rails into the blank gemset $ gem install rails # generate the new rails project $ rails new awesome_rails_project # go into the new project directory and create an .rvmrc for the gemset $ cd awesome_rails_project $ rvm --rvmrc 1.9.3@awesome_rails_project # verify the rvmrc $ cd ..; cd -
There you go. A blank slate gemset and the latest Rails, just waiting for you to code in some awesome.
