TypeError：无法读取getAssignmentTargetKind上未定义的属性“种类”

Question

将我的Angular 6项目更新到7.x时开始出现此问题。

我在angular-cli github存储库上打开了一个问题，但他们无济于事。

因此，我要做的是创建一个新项目，并一个接一个地添加所有组件，以“希望”注意到引起问题的原因。

不幸的是我无法确定问题所在。这是日志：

这是指向github问题的链接，其中包含我应该记录的checkSourcefile函数的日志：

如何跟踪并（希望）解决造成此问题的原因？

我只是重新运行

    ng serve

再次，它的工作！
