How do I avoid a file not found error installing a tarball with pip?

I'm building a local python package

cd <source dir>
python ./setup.py sdist

When I try and install it with pip, it attempts to delete a file that's not present, and fails. 

pip install --verbose dist/pl_zenoss_handler-0.1.1.tar.gz
Unpacking ./dist/pl_zenoss_handler-0.1.1.tar.gz
  Running setup.py (path:/tmp/pip-QohNov-build/setup.py) egg_info for package from file:///Users/travis.bear/p4/depot/service/python/_pl_zenoss_handler/dist/pl_zenoss_handler-0.1.1.tar.gz
    running egg_info
    creating pip-egg-info/pl_zenoss_handler.egg-info
    writing pip-egg-info/pl_zenoss_handler.egg-info/PKG-INFO
    writing top-level names to pip-egg-info/pl_zenoss_handler.egg-info/top_level.txt

<... much output deleted for brevity ... >

Problem: bin/zen_handler file missing in distribution package

The problem is, that your setup.py is asking for use of file in bin/zen_handler and in your distribution gz file it is missing.

How it went?

  1. you have the bin/zen_handler in your source tree
  2. your setup.py defines conditions for creating distribution package
  3. you create the distribution plackage
  4. you use the distribution package for installing the program
  5. distribution package does not contain bin/zen_handler and fails.

You shall check, if gz file contains the bin/zen_handler. I will assume, it is not present.

The reason is, that as it is not part of python package zen_handler itself, it is not packaged into distribution.

Resolution

Declare this non-python file to be part of distribution

Find the option for setup.py, which will declare even the bin/zen_handler as part of the distribution package. This will probably mean editing MANIFEST.in file (adding that file there) and/or using parameter include_package_data.

(preferred) Install the script using entry_points

Instead of using paremater scripts, use entry_point as described in Automatic Script Creation. As this is using purely package python source code, it does not require existence of files outside.

I recommend this solution, even though it requires little modification in your code.
