我有一个基本的 Angular 应用程序，它运行良好。 ng serve和 ng test命令工作正常。最近作为针对不同环境构建自动化的一部分，我引入了一些配置更改以允许不同的 environment.ts要根据环境加载的文件。为此，我编辑了 angular.json文件。更改后，ng serve和 ng test命令无法执行。每当执行命令时，都会抛出以下错误:
An unhandled exception occurred: No projects support the 'test' target.
See "C:\Users\account\AppData\Local\Temp\ng-BlbvgV\angular-errors.log" for further details.

最佳答案
我发现了这个问题，它放错了 } 。我在 build 之前关闭了“configuration”目标，这是导致问题的原因。已更正 angular.json :

关于Angular cli 显示错误 "An unhandled exception occurred: No projects support the ' test' target。” 运行 ng test 或 ng serve 命令时，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/60883737/
