我正在尝试使用官方文档中给出的步骤将我现有的 Angular 9 项目更新为 Angular 10。 ng update @angular/cli工作正常。

但是，我在下一步中遇到错误。 ng update @angular/core

错误 - 包“@angular-devkit/build-angular”与“typescript”具有不兼容的对等依赖项（需要 ">=3.6 < 3.9"，将安装“3.9.7”）

下面是我当前的 package.json。

  "dependencies": {
    "@angular/animations": "~10.0.8",
    "@angular/cdk": "^9.2.4",

  }
}

谁能帮我解决这个错误？

我已经通过重新安装修复了@angular-devkit/build-angular，如下所示：

npm install --save-dev install @angular-devkit/build-angular

试试看，它对我有用。

答案很晚，但可能对某人有帮助：在package.json中，将 typescript 更改为 3.9.7 然后运行npm update。之后，再次升级 Angular。应该管用

您不清楚该错误消息的哪些部分？据我所知，您需要"typescript": "~3.9.7"，但升级过程告诉您@angular-devkit/build-angular与该软件包不兼容。可能，您应该降级打字稿包
