I am attempting to setup a development enviroment for Discourse.
bundle install based on the instructions at Beginners Guide to Install Discourse on macOS for Development I get an error.
An error occurred while installing cppjieba_rb (0.3.0), and Bundler cannot continue. Make sure that `gem install cppjieba_rb -v '0.3.0' --source 'https://rubygems.org/'` succeeds before bundling.
I follow the suggestion and get the following output
$ gem install cppjieba_rb -v '0.3.0' --source ERROR: While executing gem ... (OptionParser::MissingArgument) missing argument: --source
What am I doing wrong and how can I fix the issue?
