Troubleshooting Pkg_resources.distributionnotfound Error

Why does this simple program result in a pkg_resources.DistributionNotFound error when run and how do we fix it? #setup.py from setuptools import setup setup(name='my_project',

Solution 1:

I just had this same issue. The trouble is the code works on one computer but not on another. Also I am using a wheel that I built. Anyway, the solution I found was to upgrade pip and my package. eg

pip install --upgrade pip path/to/my_package

That re-installed both pip and my package, then the entry points were working.

Solution 2:

In case you have similar issue mentioned in the question you also might have a name mismatch like I had:

setup.py

#setup.pyfrom setuptools import setup

setup(name='my_project',
    version='0.1.0',
    packages=['my_project'],
    entry_points={
        'console_scripts': [
            'my_project = my_project.__main__:main'
        ]
     },
    install_requires=[
        'req.lib',  # correct name req-lib
    ]
)

Interestingly in my case pip install -e . did not complain about the the error, but I got an error during execution, like the following one:

pkg_resources.DistributionNotFound: The 'req.lib' distribution was not found and is required by the application

Importing was not a problem there the naming was correct the following ways:

import req.lib

The package in my case was 'azure-identity' :)

The installation using pip has certainly different tolerance compared to pkg_resources.
