Deobfuscate Rake version error in generated plugin

jonathanhefner · jonathanhefner · commit 437896e249bd · 2020-02-07T15:04:48.000-06:00
If the plugin or one of its dependencies requires a version of Rake
that is different than the version executing the Rakefile,
`require 'bundler/setup'` will raise a LoadError with a helpful error
message like: "You have already activated rake 13.0.1, but your Gemfile
requires rake 12.3.3. Prepending `bundle exec` to your command may solve
this."

If that LoadError is swallowed, another LoadError will eventually be
raised with a less helpful / more confusing error message like: "cannot
load such file -- rake".
