Angular 6 : Local workspace file ('angular.json' ) could not be found

Question

我是 Angular 6 的新手，我已经从 link 下载了现成的 Angular 模板。

导航到根文件夹并执行 npm install 尝试运行应用程序 ng serve 但它显示错误

Local workspace file ('angular.json') could not be found.

webpack                      4.8.1

请帮我解决这个问题。

由于您的项目不使用 Angular-CLI，您无法执行 ng serve 导致错误，因为 ng serve 寻找此配置文件来启动您的应用程序

Local workspace file ('angular.json') could not be found.

它使用 webpack 并且所有的 webpack 配置都存储在 webpack.config.js 中。
如果你观察你的 package.json 你可以在脚本部分 start 和 build

下看到

"scripts": {
    "build": "webpack --mode production",
    "start": "webpack-dev-server --mode development --open"
  },

您可以使用 npm
执行这些脚本 执行 npm run start 进行开发构建
