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存储库。但是，当尝试将 nx cli 用于任何命令时，我收到以下错误：

    at JSON.parse (<anonymous>)
    at Object.parseJsonWithComments (/Users/bendunc/Documents/MTC Apps/mtc-language/node_modules/@nrwl/workspace/src/utils/fileutils.js:43:17)

(node:5280) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

每当我运行 nx 命令时出现此错误，例如

nx serve <app name>

或者

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

谢谢你。

一位同事帮我解决了这个问题。问题是我的 tsconfig.json 文件中有一个尾随逗号，而 JSON 不允许尾随逗号。因此，如果您遇到类似的错误，请确保您的 nx/angular 项目中的主要 JSON 文件格式正确。
