【问题描述】：
我正在尝试更新使用 Angular 11 版本开发的项目。现在我想将版本更新到 12。所以我运行了命令 ng update @angular/core@12 @angular/cli@12。但是每次出现以下错误。
E:\Workspace\My Projects\CashFlow-Web>ng update @angular/core@12 @angular/cli@12 安装的本地 Angular CLI 版本低于 最新的稳定版本。安装临时版本来执行 更新。 √ 包安装成功。 内部/模块/cjs/loader.js:888 抛出错误； ^
错误：找不到模块 'E:\Workspace\My Projects\CashFlow-Web'C:\Users\Nasir\AppData\Local\Temp\angular-cli-packages-kgrL8I\node_modules@angular\cli\bin\ng'' 在 Function.Module._resolveFilename (internal/modules/cjs/loader.js:885:15) 在 Function.Module._load (internal/modules/cjs/loader.js:730:27) 在 Function.executeUserEntryPoint [as runMain] (internal/modules/run_main.js:72:12) 在 internal/main/run_main_module.js:17:47 { code: 'MODULE_NOT_FOUND', requireStack: [] }
我确实删除了 package-lock.json 文件和 node_modules 文件夹并运行了 npm install 命令，但仍然出现上述问题当我运行更新命令时。请帮助我找到解决方案。

【问题讨论】：
-
看起来好像你的模块中有一个奇怪的引用。也许你有类似
import { something } from 'ng';的东西。或者您引用了已删除的内部控制模块。真的，这是一个检查你的文件并找到有问题的模块引用的问题。 -
您使用的是 Typescript 4.2 + 吗？你的 Node.js 版本是 11+ 吗？
-
我使用的是 typescript 4.2 而 NodeJs 是 14.17.0
-
更新时使用
--force -
使用 --force 命令不起作用
