I was getting this error, ''Cant find gem bundler (>= 0.a) with
executable bundle', after I ran `vagrant up`. The version of RubyGem
installed in the vagrant box cannot find the exact version of Bundler
listed in Gemfile.lock. This solution ensures that the exact bundler
version installed in Gemfile.lock is installed before running `bundle
install`.
The issue is solved in RubyGems >= 2.7.10 and Ruby >=2.6.3. This
solution ensures a fix without requiring a more complicated upgrade.
