--- SHOWING ERROR LOG FOR corundum-0.6.2 ----------------------

Could not find compatible versions

Because corundum >= 0.6.2 depends on bundler ~> 1.10
  and the current Bundler version (2.7.2) does not satisfy bundler ~> 1.10,
  corundum >= 0.6.2 cannot be used.
So, because Gemfile depends on corundum = 0.6.2,
  version solving has failed.

Your bundle requires a different version of Bundler than the one you're running.
Install the necessary version with `gem install bundler:1.17.3` and rerun
bundler using `bundler _1.17.3_ lock --update`
