使用 setup.py 安装包

Question

I want to create and install my own packages, so I can import functionality.py into script.py into otehr functions in the program. Following on from these instructions , I have:

Project structure

/SRC
   /package_one
        __init__.py
        script.py #Note: script.py imports from functionality.py 
   /package_two
        __init__.py
        functionality.py
setup.py

script.py

from package_two import functionality
functionality.execute()

funcitonality.py

def execute(): 
    print ("Running functinality")

setup.py

from setuptools import setup, find_packages
setup(name = 'pckage_two', packages = find_packages())

The problem

However, when i run:

C:\Users\XXXX\XXXX\src> python setup.py install 

from Terminal (in VS code with Anaconda) I get the following error:

the process cannot access the file because it is being used by another process: 'c:\\users\\XXXX\\anaconda3\\lib\\site-packages\\pckage_two-0.0.0-py3.9.egg'

other infomation

I am using Anaconda and VSCode, I have ran the python setup.py both from VScode terminal and Anaconda terminal

The documentation on that site is rather out of date and you should not (unless you know exactly what you're doing) be creating a setup.py at all, nor should you be running python setup.py install which has legacy behavior that is no longer supported.

For more up-to-date information on modern Python packaging the best place to look, as of writing, is:
