Came across a bizarre error which I thought I’d share the fix for in case anyone else comes across it: whilst trying to do a bundle install as per the gitHub pages guide, I hit this when trying to do:
tom$ bundle install
An error occurred while installing nokogiri (220.127.116.11), and Bundler cannot continue. Make sure that `gem install nokogiri -v ‘18.104.22.168’` succeeds before bundling.
Turns out you need xcode command line packages updated: check you’ve got xcode:
tom$ xcode-select –version
xcode-select version 2333.
tom$ xcode-select –install
xcode-select: note: install requested for command line developer tools
After which all plays nicely.
