已安裝的紅寶石
已安裝的devkit
ruby dk.rb init
ruby dk.rb install
然后> gem install rails(我將得到以下錯誤)
無法構建gem本機擴展 Windows 7

如果有人在Windows上遇到同樣的問題! 這是我為最終安裝Rails(和nio4r)所做的工作:
將Ruby 2.3.3降級到Ruby 2.2.6
安裝32位版本的DevKit (DevKit-mingw64-32-4.7.2-20130224-1151-sfx.exe)
cd devkit
ruby dk.rb init
ruby dk.rb review
ruby dk.rb install
cd \
gem install rails
哇!
對於同一紅寶石版本(2.3.3),降級到32位版本的DevKit(DevKit-mingw64-32-4.7.2-20130224-1151-sfx.exe)為我解決了此問題。 我不必將Ruby降級到2.2.6。
感謝您指出正確的方向!
