Question

在我的 Angular8 应用程序中，直到昨天，ng serve 和 ng test 都运行良好。但是今天，这两个命令都失败并出现错误。

An unhandled exception occurred: Invalid or unexpected token See "C:\Users\Username\AppData\Local\Temp\ng-jcwQWX\angular-errors.log" for further details.

有人可以建议是什么问题以及如何使 ng s 和 ng 测试正常运行吗？

您遇到此错误的最可能原因是您的 node_modules文件夹配置不正确，可能是您从其他来源下载了项目以及 node_modules ，所以需要重新安装软件包
sudo rm -rf node_modulessudo npm i
