Mac Sierra - could not find gem 'jekyll (~> 3.6.2)' in any of the gem sources listed in your Gemfile

Newbie
Mac OS Sierra 10.12.6 - just updated Xcode and command-line tools

  • ruby 2.4.2p198
  • jekyll 3.6.2
  • Bundler version 1.15.4
  • PATH=/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin

I can create a New site, however, when I CD to the folder and attempt:
bundle exec jekyll serve

I get the following errors:
Could not find gem ‘jekyll (~> 3.6.2)’ in any of the gem sources listed in your Gemfile.
Run bundle install to install missing gems.

and what is the result of bundle install? (:

permission error…:confused:

Is that the output of bundle install? If yes, it is most likely not a jekyll issue, but how are your permissions configured to run ruby and handle ruby gems etc. Unfortunately, not a mac user here… sorry. :confused:
