我今天一直在努力解决这个问题，并且无法弄清问题是什么 - 不幸的是谷歌没有多大帮助。
我试图关注AngularJS教程，但无法安装Karma。每次我尝试时都会收到错误说＆＃34;错误检索当前目录：getcwd：无法访问父目录：Permission denied＆＃34;。
这是bash中输出的副本：

我正在运行Node 0.10.4，顺便说一句。
不幸的是，我现在有点亏，所以任何帮助都会感激不尽！
非常感谢，

我最初问过这个问题w.r.t. OSX Mountain Lion，但我也在较新版本的OSX上遇到过类似的问题。我在下面编辑了我的答案，包括我认为对于所有版本的OSX更好的解决方案。
答案 0 :(得分：6)
好的，所以我进一步深入研究了这一点，并尝试了以下内容：
sudo npm install -g ws
这是实际无法安装的软件包。从那里谷歌搜索在StackOverflow上找到了这个：Trouble installing tower module - ws module crashes。这导致我在Macbook Pro上启用root帐户的说明：http://support.apple.com/kb/ht1528。
一旦我完成了，我现在可以在bash中执行以下命令以成功安装业力：
su
npm install -g karma
就是这样！希望这可以帮助遇到类似问题的其他人。

为了避免在OSX上使用sudo安装全局模块的整个戏剧，这可能导致奇怪的问题，例如getcwd（）由于缺乏权限而失败，我强烈建议使用nvm安装节点：{{3 }}。这样做的另一个好处是，您还可以在同一台计算机上使用多个版本的节点。
