最新版本的 node 和 npm 导致运行 karma 出现问题。当我尝试安装 karma-cli 时npm i -g karma karma-cli，我收到以下警告：

npm WARN optional Skipping failed optional dependency /chokidar/fsevents:
npm WARN notsup Not compatible with your operating system or architecture: fsevents@1.0.8
npm WARN optional Skipping failed optional dependency /gulp-karma/chokidar/fsevents:
npm WARN notsup Not compatible with your operating system or architecture: fsevents@0.2.1

当我尝试运行时karma test，出现以下错误：

Process finished with exit code 1

我的配置规范如下：

节点版本： v4.3.0
NPM 版本： 3.7.3

我无法安装业力版本，我认为它没有正确安装在我的机器上。

这不是错误。这是一个警告fseventsd，它是特定于 Mac OS 的，不能在 Linux 上安装。

没有必要惊慌，需要的包fsevents仍然可以工作——这就是为什么它是一个可选的依赖项。

由于很多人对此感到困惑（特别是因为这曾经是一个真正的错误，而不是警告），所以有一个开放的错误可以将当前警告改为 INFO

此外，纱线已经这样做了。
