javascript - 错误：TypeError：无法读取未定义的属性“标志”

}

在执行迁移时命令“ng serve”出错：

找不到“AppModule”的 NgModule 元数据中的错误。webpack：编译失败。

甚至在命令“ng build --prod”上发现的错误：

  1. 尝试清除缓存并重新安装：

    1. rm -rf node_modules dist
    2. npm 缓存清理 --force
    3. // 在 package.json 中添加最新的 typescript
    4. // 删除 package_lock.json
    5. npm 安装

  2. 尝试使用链接从头开始迁移：

    1. https://update.angular.io/

  3. 尝试删除 typescript 然后 tslint 然后 angular-cli

  4. 尝试更改 typescript、tslint、angular-cli 的版本

尝试了很多其他的东西，没有任何解决方案对我有用。
