我需要运行项目并在localhost上访问它。当我从gitlab下载该项目并解压缩它时，它发出了本地和全局CLI包不匹配的警告。然后我将本地CLI版本升级到7.1.1。从那时起，它就抛出了这个错误。全局和本地CLI程序包有问题吗？
我甚至将全局和本地CLI版本降级为1.7.4。它正在抛出ng command not found错误。我的项目文件夹中有.angular-cli.json，package.json中的@angular/cli是7.1.1。
当我从命令行运行ng serve时，我得到以下错误：
C:Usersmrunalini.prasadDesktopfsacademyfsacademy-master>ng serve
The serve command requires to be run in an Angular project, but a project definition could not be found.
我无法修复它。以下是我更新angular CLI全局和本地版本所遵循的步骤
npm uninstall -g angular-cli
npm uninstall --save-dev angular-cli
要将Angular CLI更新到新版本，必须同时更新全局程序包和项目的本地程序包。
Global package:
npm uninstall -g @angular/cli
npm cache clean
npm install -g @angular/cli@latest
Local project package:
rmdir node_modules on Windows
npm install --save-dev @angular/cli@latest
npm install
ng --version is giving the below output:
C:Usersmrunalini.prasadDesktopfsacademyfsacademy-master>ng --version

您似乎还没有将项目迁移到版本7。新的angular cli使用angular.json而不是.angular-cli.json进行配置。
请遵循迁移指南。
如果您不想更新任何内容，只想运行，请按照以下步骤操作，
- 更新angular
npm install @angular/cli -g的全局版本 - 在另一个文件夹中获取新的克隆(因为使用
--save后，您的package.json发生了更改( - 使用
npm install，现在出现不匹配错误 - 只需使用这个
ng config -g cli.warnings.versionMismatch false
我希望这会有所帮助。
