Question

根据官方升级，我将角钢从8.2.2升级到9.1.8

webpack                           4.42.0

我在CompilerFactory上遇到错误

Uncaught NullInjectorError: StaticInjectorError(Platform: core)[CompilerFactory]: 
  NullInjectorError: No provider for CompilerFactory!

下面是main.ts文件

platformBrowserDynamic().bootstrapModule(AppModule).catch(err => console.log(err));

我在线检查了一下，因为角度9支持常春藤，所以platformBrowserDynamic（）应该更改为platformBrowser（）。我将main.ts更改为

 platformBrowser().bootstrapModule(AppModule).catch(err => console.log(err));

但是对于CompilerFactory错误仍然获得相同的No提供程序。然后将main.ts更改为以下

 platformBrowser().bootstrapModuleFactory(<any>AppModule).catch(err => console.log(err));

并收到其他错误

Uncaught TypeError: Cannot read property 'name' of undefined

以下是在angular.json文件中的angular 9上添加的差异

 "options": {
            "aot": true,
}
   "configurations": {
            "production": {
              "budgets": [
                {
                  "type": "anyComponentStyle",
                  "maximumWarning": "6kb"
                }
              ],
}
