我在按照以下链接的说明在现有的角度2应用程序上实现通用cli时遇到了一些问题 https://universal.angular.io/quickstart/
在第一个安装angular-universal
的命令npm install body-parser angular2-universal preboot express --save
我收到以下错误
npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@^1.0.0 (node_modules\chokidar\node_modules\fsevents):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.0.17: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})

npm WARN angular2-universal-polyfills@2.1.0-rc.1 requires a peer of zone.js@~0.6.21 but none was installed.
执行第二个命令后，我面临下面列出的错误

我错过了什么？
答案 0 :(得分：4)
没什么，这些都是警告，而不是错误。你很可能会安全地忽略这些。它发生在依赖项之后安装依赖项时。
使用typings有点赞成@types。而不是那些命令执行这些，并删除您的本地typings文件夹：
npm install --save-dev @types/node
npm install --save-dev @types/express
npm install --save-dev @types/body-parser
npm install --save-dev @types/serve-static
npm install --save-dev @types/express-serve-static-core
npm install --save-dev @types/mime
