Fixing jekyll

After upgrading to Catalina, I could not run jekyll locally to render that website on my laptop. I was getting a weird error message about the ruby interpreter being bad.

The solution is to use a different ruby interpreter, installed via Homebrew: brew install ruby. Then update all your paths so that the command line will default to this newly installed interpreter:

export PATH="/Users/bencrestel/local/homebrew/opt/ruby/bin:$PATH"

Once this is done, we can install the jekyll gem (and bundler, but I’m not sure what that is): gem install --user-install bundler jekyll. Next, you add that to your PATH

export PATH="/Users/bencrestel/.gem/ruby/2.7.0/bin":$PATH

so that the right version of jekyll will be used. And you’re good to go.
