问题描述
我一直在尝试学习和使用nwrl nx框架来创建带有角度应用程序的新单声道仓库。但是,当尝试对任何命令使用nx cli时,出现以下错误:
at JSON.parse (<anonymous>)

每当运行nx命令(例如
nx serve <app name>
或
npx ng serve <app name>
我尝试卸载并重新安装nx cli无济于事。任何帮助或建议将不胜感激
谢谢。
解决方法
一个同事帮助我解决了这个问题。问题是我的tsconfig.json文件中的尾部逗号,而JSON不允许尾部逗号。因此,如果遇到类似的错误,请确保nx / angular项目中的主要JSON文件格式正确。
