Installing ScientificPython as a dependency

I am trying to list ScientificPython as a dependency in my setup.py. However, during the installation process, python seems to not find the package. What is wrong in my approach?

Here is my setup:

import setuptools
setuptools.setup(name = 'MyPack', version = '0.1', 
  description= 'Description.',
  author = 'Me',
  packages = setuptools.find_packages(),
  install_requires = ['ScientificPython'],
  dependency_links = ["https://sourcesup.cru.fr/frs/?group_id=180&release_id=1351#stable-releases-2-8-title-content"])

And this is the important part of the output when I run python setup.py install:

Maybe one issue is, that ScientificPython is somehow not accessible though PyPI, or at least not downloadable as easy_install ScentificPython will fail with No local packages or download links found for ScentificPython.

What do I need to do in order to install ScientificPython with setuptools?

Have you tried putting the direct download link (https://sourcesup.cru.fr/frs/download.php/2309/ScientificPython-2.8.tar.gz) into the dependency_links rather than the html page as your script seems not to find the package and then tries to install None.

edit: just noticed: python apparently is not able to open https resources - try uploading it somewhere without https, using normal http

edit 2: Why don't you just put the whole ScientificPython folder into your distribution folder and make sure its setup.py (or whatever else you need to call) is called by your setup.py?

The problem is specifically that its trying to make an http connection to a https site. From what I can tell setuptools does not support connections to https. You're going to have to use another method for getting those packages.

My recommendation, if you want to use setuptools, is that you detail in the README for the file that they have to download that dependency and install it and then have the dependency in the setuptools that fails to the install if they don't have it.

Python is unable to handle https protocol, install openssl-devel package and reinstall the python to fix this.

I was getting similar error when installing MyProxyClient using easy_install:

"Download error: unknown url type: https -- Some packages may not be found!"

and other errors about not finding openssl headers.

So installing libssl-dev (on Ubuntu) solved the problem for me!
