How to fix error while trying to install Rails with RVM - ruby-on-rails

Question

I'm trying to install Rails with RVM using the newest version of Ruby but I'm running with a problem when installing Nokogiri.
I already have some RVM gemsets that use Ruby 2.4.0 and I didn't have an issue. I installed Ruby 2.4.1 with:
rvm install ruby-2.4.0
And created a new gemset with:
rvm use ruby-2.4.1#quiniela --create
And then ran:
gem install rails --pre
And I got this error:
ERROR: Error installing rails:
ERROR: Failed to build gem native extension.

It seems that it's a problem with Nokogiri.
I followed the suggestions in "Error installing nokogiri: Failed to build gem native extension & libiconv is missing (OSX)" without success.
I updated RVM and ran gem update but it didn't work. Xcode is updated as well.
Has anyone run into this problem?

Answer 1

Try this:
gem install nokogiri -- --with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.12.sdk/usr/include/libxml2 --use-system-libraries
It solved the problem for me ...
