I'm doing a software developer course which only supports ruby 2.2.3. I was going to down load the Ruby 2.2 Windows package but am a bit apprehensive as I have already got Ruby 2.3.3 64bit installed on my laptop. The worry is it will cause issues with the newer version which I've written quite a lot of code in? I just wanted to find out if it will be ok to download this too and whether I can then switch versions with what's included in the package. I'm also using AWS cloud9 IDE which has rvm on it so I'm thinking I could switch ruby versions here?
Thanks for any help..
