[Solved] The problem that vscode writes vue3 page does not update

！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！

I have experienced many times when I was writing and suddenly the page did not respond! ! ! It was a pain, and then finally found the reason! ! ! ! ! !

The case of the configuration path file of the front-end routing is strictly distinguished. Note that if the case of the path is wrong, it may cause hot reloading to fail and no error will be reported.

Must be consistent! !
