Installing nokogiri 1.10.9 (x64-mingw32)
Gem::RuntimeRequirementNotMetError: nokogiri requires Ruby version >= 2.3, <
2.7.dev. The current ruby version is 2.7.1.83.
An error occurred while installing nokogiri (1.10.9), and Bundler cannot
continue.
Make sure that `gem install nokogiri -v '1.10.9' --source
'https://rubygems.org/'` succeeds before bundling.

In Gemfile:
  xcop was resolved to 0.6, which depends on
    nokogiri
