安裝webpack出現警告：npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@^1.0.0 (node_modules

npm install時出現警告以下：

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 ajv-keywords@3.1.0 requires a peer of ajv@^6.0.0 but none was installed

 fsevent是mac osx系統的，在win或者Linux下使用了 因此會有警告，忽略便可。

就是說安裝成功了，開始開發吧wuli乖乖
