安装webpack出现警告：npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@^1.0.0 (node_modules

npm install时出现警告如下：

npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@^1.0.0 (node_modules\ch
okidar\node_modules\fsevents):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@
1.1.3: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"}
)
npm WARN [email protected] requires a peer of ajv@^6.0.0 but none was installed

 fsevent是mac osx系统的，在win或者Linux下使用了 所以会有警告，忽略即可。

就是说安装成功了，开始开发吧wuli乖乖
