I am installing a package using dependency_links. It seems to install the package alright but breaks pip freeze functionality (which probably means there is a deeper install issue.) I want to be able to download the package from a custom server without any setup required outside of running setup.py.

This is my setup.py file:

from setuptools import setup

  setup(
      name='package'
      ,version='0.1.0'
      ,packages=['foo',
                 'bar'
                 ]
      ,long_description=''
      ,url='https://github.com/myrepo'
      ,install_requires=['numpy>=1.9.2'
                         ,'some_package'
                         ]
      ,dependency_links=[
          "http://custom_server/packages/some_package-0.1.0.tar.gz"
      ]               
  )

Install seems to work ok, but if I try and run pip_freeze I get the error below. 

pip freeze

  • I know it has to do with the fact that it's an egg file rather than an egg directory but I don't know how to fix it. – Chris Feb 26 '16 at 16:19
  • try adding #egg=some_package-0.1.0 to your dependency link – irqed Mar 01 '16 at 16:23
  • `http://custom_server/packages/some_package-0.1.0.tar.gz#egg=some_package-0.1.0` gave me the same bug when I run pip freeze. The install still works, it just breaks pip freeze :/ – Chris Mar 01 '16 at 20:06
  • Interesting. I wonder why does it says that error occurs "while executing command git rev-parse", are you sure you're not installing in from git repo? How do you install the package? `pip install .` or `python setup.py install` ? Also we can try adding `zip_safe=False` to setup call. – irqed Mar 02 '16 at 07:48
  • I am using setup.py install. Do I add zip_safe to the setup.py file? It doesn't seem to register as a valid option in the cl argument for setup.py. – Chris Mar 02 '16 at 14:55

    This worked `pip install . --extra-index-url http://10.XXX.XXX.XXX:YYYY/ --trusted-host 10.XXX.XXX.XXX`. I had to add the trusted host and extra index url options and install via pip rather than setup.py but this installs without breaking pip freeze. If you post as an answer I will accept it and give you the bounty. – Chris Mar 02 '16 at 15:09

pip install . with --extra-index-url and --trusted-host does the trick, also if you want to install it in editable mode you can do pip install -e ..

You might still want to take a look at listing dependency_links and zip_safe option: https://pythonhosted.org/setuptools/setuptools.html#dependencies-that-aren-t-in-pypi https://pythonhosted.org/setuptools/setuptools.html#setting-the-zip-safe-flag https://github.com/irqed/octokit.py/blob/master/setup.py#L51

By the way you can specify --extra-index-url and --trusted-host in pip requirements.txt file as well.
