I also install rails version 4.0.0. But I don't know how to use different versions of rails. when i create new project it shows rails version 3.x. I want to upgrade it to version 4. How to check list of all installed rails and how to use latest one. Need Help. Thank you. this is because you're still using the current gemset rails3tutorial2ndEd You need to create a different gemset: ``` rvm gemset create ``` then use it: ``` rvm gemset use ``` and finally install a new rails version: ``` gem install rails -v ``` only after doing these things will you be able to make a new project with a different rails version.
