我在按照以下链接 https://universal.angular.io/quickstart/的说明在现有 angular 2 应用程序上实现通用 cli 时遇到了一些问题

在安装 angular-universal 的第一个命令上

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？

没什么，那些是警告，而不是错误。您很可能可以放心地忽略这些。在依赖项之后安装依赖项时会发生这种情况。

的用法typings有点被弃用，取而代之的是@types. 而不是那些命令执行这些，并删除您的本地类型文件夹：

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
