类型错误:无法在 getAssignmentTargetKind 读取未定义的属性“种类" [英] TypeError: Cannot read property 'kind' of undefined at getAssignmentTargetKind

问题描述

将我的 Angular 6 项目更新到 7.x 时开始出现此问题.

This problem started to occur when updating my Angular 6 project to 7.x.

我在 angular-cli github 存储库上打开了一个问题，但他们无能为力.

I opened an issue on the angular-cli github repo but they couldn't help.

所以我所做的是创建一个新项目并一个一个添加所有组件，以希望"注意到导致问题的原因.

So what I did is create a new project and add all components one by one to "hopefully" notice what caused the problem.

不幸的是，我无法确定问题所在.这是日志:

Unfortunately I couldn't identify the problem. Here's the log:

这是我应该记录的来自 checkSourcefile 函数的日志的 github 问题链接:

Here's a link to the github issue with logs from a checkSourcefile function I was supposed to log:

我如何追踪并(希望)解决导致此问题的原因?

How can I track down and (hopefully) fix what's causing this?

    ng serve

又一次成功了！
