I have the same issue,and I think the reason is the file name contains chinese character.
I also encountered the same problem, probably using a different computer files
I have the same issue
Same issue… Epic help us pls 
Same issue. Even I deleted the directory. The issue remains active.
If you are using a git repository, check you don’t have any uncommitted deletes.
For me, the error was referring to a file in a directory which I had removed, but the removal of that directory had not been committed to the repository.
It seems that VS was referring to the last commit in GIT rather than the current state of the file system.
I found a way to solve the problem.
run the below line in cmd.
git config --global core.quotepath false
This seems to be effective, through your answer I solved the problem of compilation failure when packaging.
Thx a lot!
I solved the same error after following your command. Thx
