Sorry if this is a stupid question, but I don’t know how I got into this mess. I seem to have removed RVM itself from my application. Even when I cloned the git file to a new IDE, RVM is no longer installed. Attempting to follow a fix from https://github.com/rvm/ubuntu_rvm, I can’t ‘restart the terminal’ properly. It just won’t load. I know there may also be other errors later in the process, but my terminal won’t even install Ruby right now. Any advice?
