installing a Python package source tarball with pip

Question

I'm trying to figure out how to construct a Python source package that is installable via pip. I tried creating a test project with the setup.py file described on http://packages.python.org/an_example_pypi_project/setuptools.html and a number of simple test files in the specified directories.

After creating a source tarball for the project named dist/an_example_pypi_project-0.0.4.tar.gz with python setup.py sdist, I tried installing it in a virtualenv environment called ~/TEST with ~/TEST/bin/pip install dist/an_example_pypi_project-0.0.4.tar.gz. Although pip didn't throw any error, it didn't seem to install the package:

$ ~/TEST/bin/pip install dist/an_example_pypi_project-0.0.4.tar.gz 
Unpacking ./dist/an_example_pypi_project-0.0.4.tar.gz
  Running setup.py egg_info for package from file:///home/lebedov/an_example_pypi_project/dist/an_example_pypi_project-0.0.4.tar.gz

Cleaning up...
$ find ~/TEST -name "an_example*"
$

Note that I was able to install from the tarball using easy_install:

$ ~/TEST/bin/easy_install dist/an_example_pypi_project-0.0.4.tar.gz 
Processing an_example_pypi_project-0.0.4.tar.gz

/home/lebedov/TEST/lib/python2.7/site-packages/an_example_pypi_project-0.0.4-py2.7.egg

Am I neglecting to configure something in the package in order to make it installable with pip? I'm using Python 2.7.2, distribute 0.6.21, virtualenv 1.7, and pip 1.0.2.

The bug report you posted on github had excellent instructions to reproduce. (I commented on the ticket and copied the response here.)

I followed those instructions to the letter using those exact versions of the packages you listed and still can't reproduce this issue.

Here's my output from pip install --verbose for the command in question:

Maybe you could add --verbose to your pip install command and post the output for comparison?
