ng generate：发生未处理的异常："path" 参数必须是字符串类型。收到未定义

Question

当我运行ng g foo或ng g library foo时，我得到

An unhandled exception occurred: The "path" argument must be of type string. Received undefined

我的日志有，

[error] TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string. Received undefined

版本。

Angular CLI: 12.1.1
Node: 14.17.3
Angular: 11.2.14

对我来说，这是因为我的 angular.json 中有一个特定的不相关项目缺少

"projects": {
  "demo-app": {
    "projectType": "application"
  },
}

这可以通过删除 demo-app 条目或添加 root 条目来解决，

"projects": {
  "demo-app": {
    "projectType": "application"
    "root": "projects/demo-app"
  },
}

我已经打开了 issue #21310 to track this
