setup.py claims that my module is installed but it isn't-CodePudding

I have the following simple directory structure

root
 |- setup.py
 |- junie.py
 |- lucy.py

The contents of the files are as follows:

# setup.py
from distutils.core import setup

setup(
    name='mydogs',
    version='1.0',    
    py_modules=['junie', 'lucy']
)

# junie.py
def junie():
    print('Junie says hi')

# lucy.py
def lucy():
    print('Lucy says hi')

Neat. I run the build

$ python3 setup.py build
running build
running build_py
creating build
creating build/lib
copying junie.py -> build/lib
copying lucy.py -> build/lib

and the install

$ python3 setup.py install
running install

Hopefully I am forgiven for assuming that my package is now installed, however when I try to import it I get the following

$ python3
Python 3.10.8 (main, Oct 13 2022, 10:18:28) [Clang 13.0.0 (clang-1300.0.29.30)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import mydogs
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'mydogs'
>>>

What am I doing wrong, and why can't python find this package?

CodePudding user response：

you can run your function if you type:

import junie
junie.junie()

if you want to import mydogs, you need a file called mydogs. Anyways i would recommand you use https://setuptools.pypa.io/en/latest/userguide/quickstart.html

Because the distutils package is deprecated
