Question

我已经在https://github.com/garg10may/TourOfHeroes

上构建了Angular示例《英雄之旅》应用程序

现在，当我尝试克隆它并执行ng serve时，它给我一个错误

serve命令需要在Angular项目中运行，但是找不到项目定义。

据我了解，我没有提交angular.json文件，因此它无法识别相同文件。如何生成相同的内容？

编辑：

如果我使用另一个新项目中的angular.json文件，则会出现错误。

Could not find module "@angular-devkit/build-angular" from "/home/garg10may/TourOfHeroes".

尝试安装相同的内容：

Answer 1

您还需要从新项目中复制tsconfig.app.json和angular.json这些文件。

现在运行

npm update-> npm install-> ng serve

请记住以 sudo 的身份运行所有命令。

Answer 2

进行了一次测试。使用ng new创建了一个新项目，并添加了所有丢失的文件（不仅是angular.json）。该项目运行良好。您的问题可能与此重复：Angular6: How can I generate a default angular.json file from command line
