ruby - 安装报错rb-inotify安装

Question

我正在尝试使用以下命令安装 rb-inotify

sudo gem install rb-inotify

我得到了以下错误

Building native extensions.  This could take a while...
ERROR:  Error installing rb-inotify:
    ERROR: Failed to build gem native extension.

任何帮助将不胜感激，谢谢

首先通过运行安装ruby1.9.1-dev包

sudo apt-get install ruby1.9.1-dev

来自终端。然后像以前一样安装 rb-inotify(可能添加了 --version 标志？)

sudo gem install --version '~>0.9' rb-inotify

我已经按照这个过程修复了来自 Sass 的警告，它对我有用。
