Hello,

I am trying to compile a python script and I have to install a module called "main". when I try to install it with pip I am getting the following erorr :

Quote:ImportError: cannot import name 'Main'
PS C:\pdfconvert_source> pip install main
Collecting main

Running setup.py install for main ... error

How can I fix this ?

Thank you in advance for your help

If you write pip install main, it means that you are trying to install this module from pypi, which calculates the price of a book from its title. Is it really what you want to do?

If python writes ImportError: cannot import name 'Main', it means that it cannot import a class or function or some other python object named Main. The solution is not to use pip. If you post the whole error traceback here, it will probably help us diagnose the error.

Thank you. I am new to Python and didn't know that. I assumed it was a module.

This is what I am getting in the powershell (I am on Windows 10) :

Quote:PS C:\Users\admin> cd C:\pdfconvert_source
PS C:\pdfconvert_source> python starter.py
Traceback (most recent call last):
File "starter.py", line 4, in <module>
from pdfconvert_qt import Main
File "C:\pdfconvert_source\pdfconvert_qt.py", line 14, in <module>
import starter
File "C:\pdfconvert_source\starter.py", line 4, in <module>
from pdfconvert_qt import Main
ImportError: cannot import name 'Main'
PS C:\pdfconvert_source>

Do you have a link to what you are trying to install?

No it's a program that was made by a friend of mine... does the error I am getting means there is something wrong with the script?

The error means that python detects a cyclic import: the starter.py file needs to import an object named Main from the file pdfconvert_qt.py, and this file in turn needs to import the starter module. This is a design flaw in the program. There may be solutions, but without the code it is difficult to help.
