How to install Nokogiri on Ruby 2.7.0

I recently upgraded to Ruby v2.7.0.

When I tried to install Nokogiri I got the following error:

ERROR:  Error installing nokogiri:
        The last version of nokogiri (>= 0) to support your Ruby & RubyGems was
1.10.9. Try installing it with `gem install nokogiri -v 1.10.9`
        nokogiri requires Ruby version >= 2.3, < 2.7.dev. The current ruby versi
on is 2.7.0.0.

I tried to install this gem with

gem install nokogiri -v 1.10.9

but I got the same error.

How can I install Nokogiri now that I am using Ruby v2.7.0? Do I need to install an earlier version of Ruby?

The results of gem env are:

If you're using Ruby + DevKit, try this command:

gem install nokogiri --platform=ruby

It should install nokogiri and make it fit with your version of Ruby. In case if it fails again or takes forever to fetch and install gem, run this command first:

ridk exec pacman -S mingw-w64-x86_64-libxslt

Then this one:

gem install nokogiri --platform=ruby -- --use-system-libraries

Nokogori should be installed after these commands.
