I\'m running a clean install of Ruby 2.2.1 on Windows 8.1 with DevKit. After the installation I run:
gem install rails
rails new testapp
cd testapp
rails ser
First, uninstall the version of Nokogiri you currently have with:
gem uninstall nokogiri
Download Nokogiri 1.6.6.2 (x64) or Nokogiri 1.6.6.2 (x86)
Install this version locally using:
gem install --local C:\Users\$user$\Downloads\nokogiri-1.6.6.2-x64-mingw32.gem
or if you're running 32bit Ruby:
gem install --local C:\Users\$user$\Downloads\nokogiri-1.6.6.2-x86-mingw32.gem
The path may differ depending on where you downloaded the file to.
Try to start the server again using ruby bin\rails server
, and it should work.
