Angular 7 开发自定义库时，引用ngZorroAntd，build过程中出现

No name was provided for external module 'ng-zorro-antd' in output.globals – guessing 'ngZorroAntd' 错误 

解决方法： 

在库所在目录的ng-package.json中，填加红色部分

{
  "$schema": "../../node_modules/ng-packagr/ng-package.schema.json",
  "dest": "../../dist/test-lib",
  "lib": {
    "entryFile": "src/public_api.ts",
    "umdModuleIds": {
      "ng-zorro-antd": "^7.0.0-rc.1"
    }
  }
}
