Answer 1

wenn jemand läuft in dasselbe Problem unter Windows! Hier ist, was ich tat, Rails zu bekommen (und nio4r) schließlich installiert:

Herunterstufung Rubin 2.3.3 Ruby 2.2.6

Installieren Sie die 32bit Version des 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 

WAH LAH!

Answer 2

Downgrade auf 32-Bit-Version des DevKit (DevKit-mingw64-32-4.7.2-20130224-1151-sfx.exe) für die gleiche Ruby-Version (2.3.3) behob dieses Problem für mich. Ich musste Ruby nicht auf 2.2.6 herunterstufen.

Danke, dass Sie mich in die richtige Richtung weisen!
