ng s启动完,在命令行和浏览器console里提示编译失败:

用node的npm按装完Angular4,在安装Material2,各个组件版本如package.json所示,出现上述异常,但是没有安装Material2之前,此Angular4的app是可以正常工作的,

分析应该是此Material2的版本2.0.0-beta.8和此Angular4的版本不兼容导致的,


package.json

You should list all the peer dependencies that your library uses in ./tsconfig.json, pointing them at the local copy in the apps node_modules folder. This ensures that you all will always load the local copies of the modules your library asks for

{  "compilerOptions": {    // ...    // Note: these paths are relative to `baseUrl` path.    "paths": {      "@angular/*": [        "../node_modules/@angular/*"      ]    }  }}
