Python の卵の依存関係の直接ダウンロード リンクを指定できますか?
依存関係として Skype4Py があり、easy_install が sourceforge.net からファイルを正しくダウンロードできないようです (sourceforge.net の問題)。結果の tar ファイルはスクランブルされます。https://github.com/stigkj/Skype4Py/issues/3
この問題を回避するには、sourceforge.net の問題を回避するために、Skype4Py アーカイブの直接ダウンロード リンクを指定したいと思います。
First of all, I highly recommend using pip instead of easy_install as it's simply better in nearly every aspect.
You can't specify direct download link directly in setup.py but that's a good thing. Decision where to look for a dependency should be made at installation time. Pip has a few options allowing to configure where to look for packages; --index-url, --extra-index-url and --find-links. However in your situation I think the simplest solution would be to install the dependency that fails to install from its default location using some alternate location first and then install the package that uses it like so:
pip install alternate_location_of_dependency
pip install some_package_having_above_depedency
Taking human_curl package, which depends on pycurl2 package, as an example that might be:
pip install https://github.com/pycurl2/pycurl2.github.com/archive/master.zip
pip install human_curl
