Question

StackOverflow上的所有答案似乎都没有帮助我，也许是因为它们都是指Angular的较旧版本。

我是一个完全的新手，正在尝试启动第一个Angular项目。我做了npm install -g @angular/cli

ng new first-ang cd first-ang 但是当我执行ng serve时，它为我提供了“无法从“ D：\ Angular \ ang”中找到模块“ @ angular-devkit / build-angular”。有关更多详细信息，请参见“ C：\ Users \ Susanna \ AppData \ Local \ Temp \ ng-hjBvo0 \ angular-errors.log”。

错误日志包含以下内容：

[error] Error: Could not find module "@angular-devkit/build-angular" from "D:\\Angular\\ang".
    at Object.resolve (C:\Users\Susanna\AppData\Roaming\npm\node_modules\@angular\cli\node_modules\@angular-devkit\core\node\resolve.js:151:11)
    at WorkspaceNodeModulesArchitectHost.resolveBuilder (C:\Users\Susanna\AppData\Roaming\npm\node_modules\@angular\cli\node_modules\@angular-devkit\architect\node\node-modules-architect-host.js:31:40)

    at startup (internal/bootstrap/node.js:283:19)
    at bootstrapNodeJSCore (internal/bootstrap/node.js:622:3)

这是package.json文件的样子：

  "name": "ang",
  "version": "0.0.0",
  "scripts": {
    "ng": "ng",
    "start": "ng serve",
    "build": "ng build",

  }
}

我已经尝试更新npm并执行Stackoverlfow上已列出的几乎所有内容，但无济于事。有谁知道如何处理最新版本的Angular？

（链接到我已经尝试过的解决方案： Could not find module "@angular-devkit/build-angular" Could not find module "@angular-devkit/build-angular" with ng serve ng serve is not working after Angular 8 update ）

PS：我注意到我的package.json文件没有“ angular-cli”依赖性。这有问题吗？

在具有packages.json的文件夹中运行X:\，以便还原所有必需的软件包。（不是npm install）

使用ng服务时出现Angular8错误：找不到模块“ @ angular-devkit / build-angular”
