问题 There are two Ruby projects I am currently working on which have both a .rvmrc and a .ruby-version file in their root dir. I use rvm to manage my Ruby versions in my local development environment, and have my own local .rvmrc files in my home directory's copy of various Ruby versions, so naturally I get the rvm warning when I change directory into these projects: You are using '.rvmrc', it requires trusting, it is slower and it is not compatible with other ruby managers, you can switch to '

This causes Passenger to move other applications to swap when one is accessed, which means each time a different application is accessed, it has to be

问题 My Rails 3.2 / Ruby 1.9.3 app is using RVM. I want to upgrade to using ruby 2.1.5. I have used RVM to install Ruby 2.1.5 as well. So rvm list shows both 1.9.3 and 2.1.5 My project directory has a .rvmrc file specifying environment_id="ruby-1.9.3-p551@current_foogems" So I have a gemset named current_foogems How can I switch my project to use ruby 2.1.5? Do I copy the gemset? Create a new (empty) gemset? Given the jump in ruby version from 1.9.3 to 2.1.5, which may mean I should recompile gems

问题 When executing a bash shell script I am using ruby 1.9.3. Then, within the script, I want to switch to JRub (I'm using rvm).
