Question

I find that recently often when I try to install a Python package using pip, I get the error(s) below.

I found a reference online that one has to use “python2 setup.py install” from the download directory, and indeed find that this will then work if I manually find and download the package (from pypi).

But, I don’t know where pip is downloading packages to, and/or why it is failing in this manner.

I tried to do a pip upgrade, but it also failed in a similar manner, with a bunch of “Unknown distribution option” errors (entry_points, zip_safe, test_suite, tests_require)!

• pip 1.0.1
• ActivePython 2.7

Trying to use ActiveState’s pypm fails, because they have a smaller library base, and it doesn’t include these packages.

Answer 1

Install distribute, which comes with egg_info.

Should be as simple as pip install Distribute.

Distribute has been merged into Setuptools as of version 0.7. If you are using a version <=0.6, upgrade using pip install --upgrade setuptools or easy_install -U setuptools.
