rvm

问题 I am not able to switch the current Ruby version: ➜ ~ rvm list rvm rubies ruby-1.9.2-p290 [ x86_64 ] ruby-1.9.3-p0 [ x86_64 ] ➜ ~ rvm use ruby-1.9.3-p0 RVM is not a function, selecting rubies with 'rvm use ...' will not work. 回答1: Fixed it. I needed to add: [[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # This loads RVM to .zshrc 回答2: This happened to me too. I had: export PATH=~/.rvm/bin:$PATH Added in my .bashrc. All I had to do was add another [[ -s "$HOME/.rvm/scripts/rvm

问题 Q: Do we have anything functionally equivalent in Python to the Ruby version manager 'rvm'?

问题 I want to switch between rails 2.3.10 as the \"active\" gem for my OS, so that I can invoke it at the command line. Is it possible to do this? I\'m not using rvm. Maybe it\'s time to start. I tried gem install rails --version=2.3.10 , but that just makes sure that version of the gem is installed, it doesn\'t put it in /usr/bin/rails . (I do already use bundler for my apps -- but haven\'t needed any precise control over gems at the OS level until now) 回答1: If your problem is to run binaries of
