Old question, but I ran into this issue just now, and there is a new fix for it. If you're using Ruby version <= 2.6.1, and Bundler 2.0.1, update Ruby to 2.6.3 ($ rvm install "ruby-2.6.3") and Bundler to 2.0.2 ($ gem install bundler '2.0.2'). Make sure to specify the new Ruby version in your Gemfile.

Unfortunately I can't tell you why this works, but it's worked for 3 other people on my team so far, so it's worth a shot.
