#StackBounty: #pip #console-application #setup.py #pkg-resources fragile console script: pkg_resources.DistributionNotFound

Bounty: 50

If I create console_scripts via entry_point in setup.py, then this file gets created:

# EASY-INSTALL-ENTRY-SCRIPT: 'mylib','console_scripts','do-magic'
__requires__ = 'mylib'
import re
import sys
from pkg_resources import load_entry_point

if __name__ == '__main__':
    sys.argv[0] = re.sub(r'(-script.pyw?|.exe)?$', '', sys.argv[0])
        load_entry_point('mylib', 'console_scripts', 'do-magic')()

Unfortunately this script is fragile.

Sometimes I get exceptions like this:

Traceback (most recent call last):
  File ".../bin/do-magic", line 6, in <module>
    from pkg_resources import load_entry_point
  File ".../local/lib/python2.7/site-packages/pkg_resources/__init__.py", line 2999, in <module>

    needed = self.resolve(parse_requirements(requirements))

    raise DistributionNotFound(req, requirers)
pkg_resources.DistributionNotFound: The 'PyPDF2==1.26' distribution was not found and is required by mylib

Is there a way to make my script (do-magic) more mature?

In this case: It does not need PyPDF2.
