Why are there no build and package-lock.json files? it"s strange that there are no git pages. When my newly cloned project runs npn run dev, it will report an error that the files in build cannot be found. I"m fine here. There"s nothing wrong with it. And since there are no two files on the page, I didn"t report any errors when I added and modified things in the local git. Why are those two files suddenly not available on the web page git?
