Pycharm gets error “can't find '__main__' module”

问题

Whenever I try to run script via Virtualenv in pycharm, i get this error:

C:\Users\Costello\PycharmProjects\test\venv\Scripts\python.exe C:/Users/Costello/PycharmProjects/test
C:\Users\Costello\PycharmProjects\test\venv\Scripts\python.exe: can't find '__main__' module in 'C:/Users/Costello/PycharmProjects/test'

Everything works fine via idle, or vs code. I figure it must be something with a way that I have setup my pycharm but have no idea what.

edit: this happens whatever I run, even simple print function.

edit: even with choosing regular python intepreteur, same happens just in pycharm

C:\Users\Costello\AppData\Local\Programs\Python\Python37\python.exe: can't find '__main__' module in 'C:/Users/Costello/PycharmProjects/test'

Figured out whats wrong. In the configuration window in pycharm, I had to select proper script path:

回答2:

In your Pycharm:

Select Run - Edit Configurations
In Configuration tabs, select Module name in option Choose target to run and type your python file's name
Click Apply and OK button

Or the simple way is when you run your code for first time (on a new file) just type keyboard Alt+Shift+F10 to run and save the configuration. On the second time (after configuration is saved) just type Alt+F10 to run your code.

I fixed it by removing values from Interpreter options field in run/debug configurations. While trying to add an interpreter, I had added the python path to the mentioned field.

After clearing out the field all worked well.

You can find run/debug configuration settings in the drop-down left of run icon on top-right of pycharm window.

Go to "Edit Configuration" and only speciy your filename like filename.py

Existing path -----> C:\Users\np4\PycharmProjects\TEST\venv

Try with this -----> C:\Users\np4\PycharmProjects\TEST\venv\MultiSites.py

I encountered this problem when my cmd was forced to "End Task" by "Task Manager". My problem solved when I restart my IDE.

回答6:

"Open 'Edit Run/Debug configurations' dialog" (on the top, next to "Run") "Edit Configurations" "script path:" --> select correct script path.

回答7:

In Pycharm (Ubuntu):

Create New Project
Give Project Name
Right Click on bin folder
Create New Python File
Write Your Code
Upper Right Side: Add Configuration
Left side: right click on "+" sign
Input full file name
Home/Downloads/myfile.py as "Script path"
python 2.x/3.x as Python Interpreter
Click on apply / ok
