javascript - webpack error reporting is ambiguous

Question

I use vue-cli to build projects and often encounter errors, but I can’t find clear information at all from the error messages. For example, there is no clear file and line where the error is reported (as shown below). For example, I don’t know how to add a break. Point, novice feels these error reports are very unfriendly, please let me know the correct debugging posture (mainly for one type of problem, not for a specific problem), thank you.

Answer 1

You can send a screenshot of the error report so that others can help you

Answer 2

There are many wrong situations. If you don’t take the picture, no one can solve it for you!
