【问题描述】：

我只是使用 angular cli 创建一个项目，然后运行命令“ng add @nrwl/workspace”将其更改为 nrwl 工作区。但我收到以下错误“无法读取未定义的属性'路径'”。

我在互联网上搜索了一下，发现有人有类似的错误，但他的错误是在 angular.json 中的测试丢失了我的 angular.json 中有所需的一切。

是否有人可以查看我的 json 文件并说出可能导致此错误的原因。我正在使用 nrwl 和 angular 的最新版本

【问题讨论】：

v10 是否发生了这种情况？如果问题在 v10 中仍然存在，您是否可以在 nrwl/nx 存储库中提出问题。

【参考方案1】：

我也遇到过这种问题，我是这样解决的：在根目录tsconfig.json中需要一个paths参数。 像这样：

  "compilerOptions": 
    "paths":
