python http.server not working

[BoxLoginInfo]

I don't know what happened, but every time I run "python3 http.server 80" I get this error message:

python3: can't open file '/root/http.server': [Errno 2] No such file or directory

I tried reinstalling python to no avail.

Try
sudo python3 -m http.server 80.
