We’re about to update the application to require Ruby 2.2. (#4529)
The appliance has been running on 2.2 for several months, as have many developers, so we know everything works.
If you’re currently using Ruby 2.0 (or 2.1), you should upgrade at your earliest convenience: the Gemfile will start refusing to run on older versions in a couple of days, ready for the Capablanca beta.
There are many variations to how your system might be set up – if you know how to do this, just do whatever will work. If you’re not sure, try one of these…
rvm get stable rvm install 2.2.3 rvm --default use 2.2.3 bundle install
rbenv + ruby-build:
brew update brew upgrade ruby-build rbenv install 2.2.3 rbenv global 2.2.3 bundle install
ruby-install ruby 2.2.3 # update your ~/.bashrc or ~/.zshrc to call "chruby 2.2" # restart your shell bundle install
If you still seem to be using the older version (
ruby --version), check for a
.ruby-version file in the local directory.
