运行 ng serve 时出现以下错误

Question

我是新手，我对 VSCode 有疑问。运行 ng serve 时出现以下错误：

---

PS C:\Windows\System32\x-app> ng serve --configuration=it
An unhandled exception occurred: Workspace config file cannot le loaded: C:\Windows\System32\x-app\angular.json    
Invalid JSON character: "\"" at 73:7.
See "C:\Users\C-PROJ~1\AppData\Local\Temp\ng-LpcKJr\angular-errors.log" for further details

我使用prettier，事实上，我注意到内部化存在疏忽。我修复了json文件，返回了命令ng serve --configuration=it，结果又报错了。

PS C:\Windows\System32\x-app> ng serve --configuration=it

Answer 1

您的angular.json 可能格式不正确。请检查文件是否符合json 标准。你可以使用prettier之类的工具来格式化json。
