Vue-cli project version update, how to avoid switching back and forth between the old version and the new version?

vue-cli project version update, there is a strange phenomenon. Enter a link to a page directly in the browser and have been updated to the new version. At this time, if you click logo to get to the home page, and then go back to the previous link, the interface goes back to the previous version. Refresh and new version, then click logo to go to the home page and come back to the old version. Back and forth.
if you click on the home page and swipe the page, you can keep the new version. Feel more strange, no wrong report no warning, what is the cause of this problem? Have you ever met a great god? Please also advise
