ModuleNotFoundError: No module named 'core'

Hi. Fast question. I get that error (in title) when I try run python script/ and others…
But. I wrote export PYTHONPATH=".;$PYTHONPATH" in my .bashrc and i restarteed the bash but still writes this error.


the program works in Command Prompt as long as PYTHONPATH is set in your system’s variables, so i suggest you try that.

oh, it is too difficult for me. then forget it
