javascript - 错误: Internal error: unknown identifier

Question

当我运行时，我想发布我的 Angular 应用程序以进行生产

ng build --prod --aot = false

它构建成功，但 main.js 文件很大(6 MB)，与vendor.js(10 mb)相同，这使得我的应用程序如此缓慢。所以我尝试使用 ng build --prod 运行，但出现此错误

ERROR in : Error: Internal error: unknown identifier [{"filePath":"C:/Users/myuser/Documents/anular-app/angularpp_test/Client/myweb/node_modules/@angular/core/core.d.ts","name":"ErrorHandler","members":[]}]

这是我的配置

Angular CLI: 6.0.7
Node: 8.9.4
OS: win32 x64
Angular: 5.2.0
... animations, cdk, common, compiler, compiler-cli, core, forms
... http, language-service, material, platform-browser

查看您的 app.modules，特别是您的提供商所在的位置。必须使用

provide: [ErroHandler]

删除这个括号。
