Angular CLI 错误 : The serve command requires to be run in an Angular project, 但找不到项目定义

Question

当运行终端命令 ng server 或 ng serve --live-reload=true 时，我遇到了这个问题:

The serve command requires to be run in an Angular project, but a project definition could not be found.

Answer 1

我也遇到了这个问题并通过运行以下命令解决了。

ng update @angular/cli --migrate-only --from=<WhateverVersionYouAreCurrentlyOn>

例如

ng update @angular/cli --migrate-only --from=1.7.3
