ruby - 在 OS X Yosemite 上安装 compass

Question

我正在尝试使用 GEM 安装 compass ，但我遇到了很多错误。

我的 macbook pro 运行的是 OS X Yosemite。

有人遇到同样的问题吗？

感谢您的宝贵时间。祝你有个愉快的一天

extconf failed, exit code 1

Gem files will remain installed in /Library/Ruby/Gems/2.0.0/gems/ffi-1.9.5 for inspection.

Answer 1

实际上，这似乎在Installing 'Compass' via the command line receive error "extconf failed, exit code 1" 得到了成功的回答。

你显然需要先安装开发工具(xcode-select --install)，然后再安装compass

祝你好运!
