我正在尝试将我的项目中的 Angular 从版本 10.2 更新到 11.0。运行 ng 更新：

  @angular-devkit/build-angular      0.1002.0 -> 0.1100.1     ng update @angular-devkit/build-angular
  @angular/cdk                       10.2.7 -> 11.0.0         ng update @angular/cdk
  @angular/cli                       10.2.0 -> 11.0.1         ng update @angular/cli
  @angular/core                      10.2.3 -> 11.0.0         ng update @angular/core
  @angular/material                  10.2.7 -> 11.0.0         ng update @angular/material

不幸的是，我尝试更新的每个软件包都失败了。我尝试了 --force 和 --allowDirty 标志。

我遇到了完全相同的问题，尝试了不同的升级顺序，多次删除了 node_modules 文件夹，但仍然没有运气。对我来说，问题在于我使用的是 Node v15。我卸载了它并重新安装了 Node v14 -> 工作

有同样的问题。对我来说，问题是代码编辑器是打开的，

关闭编辑器并运行ng update @angular/core @angular/cli角度成功更新

就我而言

  • 删除 node_modules 和 package-lock.json
  • npm 缓存清理 --force
  • npm i --force

我认为问题是在节点升级到 v14 之后

我遇到了同样的问题，只需删除 node_modules、package-lock.json 并运行 npm install，现在一切正常！

我有同样的问题，我最终使用了纱线包管理器，它解决了这个问题。
