Angular migration from 12 to 13 getting error : Cannot destructure property 'styles' of 'buildOptions.sourceMap' as it is undefined

Question

我正在尝试将我的 angular 版本从 12 升级到 13 但出现错误 “发生未处理的异常：无法解构 'buildOptions.sourceMap' 的属性 'styles'，因为它未定义。”

我正在使用官方网站上提供的以下命令 npx @angular/cli@13 更新@angular/core@13 @angular/cli@13

请任何人帮助我

不幸的是，我无法在 angular.json 中找到添加 sourceMap 配置的有效位置。我所做的成功是通过创建一个新项目并将新 angular.json 的内容复制到我的旧项目来重置文件，然后在不匹配的地方更改项目名称。

该文件的示例版本如下：

{
  "$schema": "./node_modules/@angular/cli/lib/config/schema.json",
  "cli": {
    "analytics": false
  },
  "version": 1,

我删除了软件包-lock.json，删除了 node_modules 文件夹并安装了 npm，它解决了这个问题。

如果有人在从 Angular 12 升级到 13 时遇到此问题，只需

replace this text '@ngx-env/builder' with '@angular-devkit/build-angular' in angular.json
