Protractor对我来说运行良好数周，测试 Chrome 和 Firefox 。
然后 Chrome 测试开始失败。
然后Protractor根本不会运行。
然后根本找不到Protractor。
然后我无法更新或安装它或其他任何东西。
我是新生的，我真的不知道我在做什么。
几天前，我的经理让我在我的电脑上install Norton AV。它会以某种方式干扰吗？如果是这样的话，我该怎么办？
当我再次尝试NodeJS时（在管理员模式下运行。我在管理员内外都试过了），这是install Protractor的示例错误日志。

第45行看到的错误EPERM是一个npm权限错误。可以使用npm cache clean修复，然后您可能必须删除%APPDATA%\npm-cache目录中的所有内容。
