#1 楼 @i5ting 谢谢 sudo apt-get install zlib1g sudo apt-get install zlib1g.dev
这两个都安装了，再次安装出现以下错误。 gem install rails Building native extensions. This could take a while... ERROR: Error installing rails: ERROR: Failed to build gem native extension.

然后根据错误提示，安装: sudo apt-get install build-essential patch sudo apt-get install libgmp-dev
然后再安装：gem install rails rails -v Rails 4.2.5
OK 了，谢谢
