Issues installing python package Six (to install Pip)

We recently uninstalled pip to do some cleanup on Mac OS X El Capitan. Now trying to re-install pip.
$ sudo easy_install pip
Traceback (most recent call last):
File "/usr/local/bin/easy_install", line 11, in <module>

Looks like we need to upgrade Six. So:
$ easy_install --upgrade six

Now it looks like we need to upgrade Six in order to upgrade Six??? Maybe it's just a permissions issue:
$sudo easy_install --upgrade six

Nope. Same error.
I'm obviously missing something. Can someone shed some light on this?

Python 2.7.9+ and 3.4+
Good news! Python 3.4 (released March 2014) and Python 2.7.9 (released December 2014) ship with Pip. This is the best feature of any Python release. It makes the community's wealth of libraries accessible to everyone. Newbies are no longer excluded from using community libraries by the prohibitive difficulty of setup. In shipping with a package manager, Python joins Ruby, Node.js, Haskell, Perl, Go--almost every other contemporary language with a majority open-source community. Thank you Python.
Of course, that doesn't mean Python packaging is problem solved. The experience remains frustrating. I discuss this in Stack Overflow question Does Python have a package/module management system?.
And, alas for everyone using Python 2.7.8 or earlier (a sizable portion of the community). There's no plan to ship Pip to you. Manual instructions follow.
Python 2 ≤ 2.7.8 and Python 3 ≤ 3.3
Flying in the face of its 'batteries included' motto, Python ships without a package manager. To make matters worse, Pip was--until recently--ironically difficult to install.
Official instructions
Per https://pip.pypa.io/en/stable/installing/#do-i-need-to-install-pip:
Download get-pip.py, being careful to save it as a .py file rather than .txt. Then, run it from the command prompt:
python get-pip.py
You possibly need an administrator command prompt to do this. Follow Start a Command Prompt as an Administrator (Microsoft TechNet).
Alternative instructions
The official documentation tells users to install Pip and each of its dependencies from source. That's tedious for the experienced, and prohibitively difficult for newbies.
For our sake, Christoph Gohlke prepares Windows installers (.msi) for popular Python packages. He builds installers for all Python versions, both 32 and 64 bit. You need to
Install setuptools
Install pip
For me, this installed Pip at C:\Python27\Scripts\pip.exe. Find pip.exe on your computer, then add its folder (for example, C:\Python27\Scripts) to your path (Start / Edit environment variables). Now you should be able to run pip from the command line. Try installing a package:
pip install httpie
There you go (hopefully)! Solutions for common problems are given below:
Proxy problems
If you work in an office, you might be behind a HTTP proxy. If so, set the environment variables http_proxy and https_proxy. Most Python applications (and other free software) respect these. Example syntax:
http://proxy_url:port
http://username:password#proxy_url:port
If you're really unlucky, your proxy might be a Microsoft NTLM proxy. Free software can't cope. The only solution is to install a free software friendly proxy that forwards to the nasty proxy. http://cntlm.sourceforge.net/
Unable to find vcvarsall.bat
Python modules can be part written in C or C++. Pip tries to compile from source. If you don't have a C/C++ compiler installed and configured, you'll see this cryptic error message.
Error: Unable to find vcvarsall.bat
You can fix that by installing a C++ compiler such as MinGW or Visual C++. Microsoft actually ship one specifically for use with Python. Or try Microsoft Visual C++ Compiler for Python 2.7.
Often though it's easier to check Christoph's site for your package.

Error in installing setuptools (unorderable types: str() < NoneType())

First I was trying to upgrade setuptools, but it was not successful. So I decided to uninstall the previous version. Now I can't install setuptools. I have tried the following:

I think uninstalling and reinstalling python would fix the problem, but before trying that I thought maybe you can help me to find the cause of the problem and the right way to fix this. Thanks.

I was able to solve my problem (on Win 8.1 64bit, Python 3.4.2) with the change suggested here:
https://bitbucket.org/pypa/setuptools/pull-request/122/ensure-py_version-and-platform-are-str-in/diff#chg-pkg_resources/init.py

Instead of downloading ez_setup.py, use get-pip.py instead. From the docs, if setuptools is not installed, it will install it first.
Since you're still getting an error, try installing pip and setuptools from Christoph Gohlke's Python Extension Packages for Windows repository. Make sure you download the 32-bit installers for Python 3.4. Once downloaded, run the .exe files and hopefully everything will be back to normal. There are tons of scientific computing packages there, so if you want numpy linked against Intel's MKL, and scipy, which uses the enhanced version of numpy, go right ahead!

Well it seemed to me that my python installation was completely messed up. It could have been related to a temporary installation of python 2 on my system a few weeks ago. Anyway, I thought it would be easier for me to just uninstall and reinstall the whole thing. So I uninstalled python and then reinstalled, but even that was not enough. Finally, I manually deleted C:\Python34 and reinstalled python and now it works fine.

Have I not installed cx_freeze correctly? Or am I running it all wrong?
Help is greatly appreciated.
Thanks

Well, I found an answer that works for me.
Turns out there's a bug in cx_Freeze 4.3.4 and downgrading to 4.3.3 solved this problem for me.

Try opening up the util.pyd file with a tool like Dependency Walker in order to check if the error is a result of missing dependencies. I found that it was trying to load msvcr100.dll from the Microsoft Visual C++ 2010 runtime which I did not have installed on my machine. If this is also the source of your error, you can try running the x86 / x64 installer to see if this addresses it (you want to pick the one that matches the architecture of your Python installation not of your OS).

I summarized above in my blog.

To install Visual Studio 2008 Express Edition with all required components:
Install Microsoft Visual Studio 2008 Express Edition. The main Visual Studio 2008 Express installer is available from (the C++ installer name is vcsetup.exe):
Install the Microsoft Windows SDK. The Microsoft Windows SDK is available by searching Microsoft's download site, or by going directly to:
http://www.microsoft.com/downloads/details.aspx?FamilyId=F26B1AA4-741A-433A-9BE5-FA919850BDBF&displaylang=en
To verify that you have all installed components, check that the Microsoft SDK contains the "amd64" version of the C/C++ compiler "cl.exe". This is usually installed into
C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin\amd64\cl.exe
copy .../VC/bin/vcvars64.bat to .../VC/bin/vcvarsamd64.bat
copy .../VC/bin/vcvars64.bat to .../VC/bin/amd64/vcvarsamd64.bat

Since you're using the 64 bit version of Python, once you have installed Microsoft Windows SDK for Windows 7 and .NET Framework 3.5 SP1 (which installs the 64bit compiler that isn't installed when installing Visual Studio 2008 SP1 Express Edition); You need to copy the vcvars64.bat to a location where vcvarsall.bat claims it to be.
From %CSIDL_PROGRAM_FILESX86%\Microsoft Visual Studio 9.0\VC\bin\, you need to copy vcvars64.bat to amd64\vcvarsamd64.bat.
Note the amd part in the destination file name.

Microsoft now publishes a Visual C++ compiler just for Python 2.7, although it will work for other versions of Python that used the same compiler. Check the system requirements: setuptools 6.0 or later is required. It will not work with packages using distutils.

I experienced this issue because I did not have the 64-bit version of Visual C++ 2008. To solve the issue, I installed it through Change/Remove in Programs and Features, following this answer.

I had this same problem, but just renaming the files listed above (in a somewhat opaque way) didn't work for me. What did work is a much easier solution. Just run vcvarsall.bat before you start the install. This sets the correct paths and is much easier to understand. In my case, I needed a 64 bit build so I ran:
"C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\vcvarsall.bat" x64

Problem using easy_install on Windows 7, 64 bit. (cannot find python.exe)

I have just now installed Python 2.6 on my Windows 7 (64 bit) Lenovo t61p laptop.
I have downloaded Sphinx and nose and apparently installed them correctly using
python setup.py install
(at least no errors were reported during the installation).
Now I am trying to install pymongo using easy_install but I am not having much success. It seems that easy_install isn't working at all. I execute easy_install as administrator:
C:\>easy_install
Cannot find Python executable C:\Program Files\Python26\python.exe
The path C:\Program Files\Python26\python.exe is correct.
I have found this bug report on bugs.python.org which seems to be related, although its status is 'Resolved'.
Do you have any ideas as to what may be wrong? Any pointers, hints or tips for diagnosing the problem further would be greatly appreciated.

PS.: I previously installed Python 3.1 but later installed 2.6 because I am not sure whether pymongo supports 3.1.
PPS.: I have tried installing pymongo using the python setup.py install approach, but this resulted in a nasty-looking stack trace, so I thought I would try to let easy_install take care of it for me.
PPPS.: I am completely new to Python, easy_install, eggs etc.

I don't know anything about these specific packages so I may not be much help. But for what it's worth I have run into the "can't find python executable" errors before with 64 bit python. It happened when the package I was trying to install didn't have a 64 bit version and it was looking for 32 bit python. I ended up just installing and using the 32 bit python. That may not be the issue here, but I figured I'd through it out there.

can't help much with easy_install - but python setup.py install should work w/ pymongo. what was the stack trace?

Install this 64-bit version of setuptools instead.
