问题
I am trying to run tox tests as python 2.6. I just installed 2.6 and am now getting past the "Interpreter error: no python 2.6" style error, but tox is now crashing at zlib. Zlib is on my machine however. My tox issue looks like:
$ tox -e py26

I tried upgrading these:

$ sudo apt-get install --upgrade zlibc zlib1g zlib1g-dev

zlib1g is already the newest version.
zlib1g-dev is already the newest version.
zlibc is already the newest version.

Python 2.6 is working, but when I installed it I got the warning:
Failed to find the necessary bits to build these modules:
_bsddb _curses _curses_panel
_hashlib _sqlite3 _ssl
_tkinter bsddb185 bz2
dbm dl gdbm
imageop linuxaudiodev ossaudiodev
readline sunaudiodev zlib
To find the necessary bits, look in setup.py in detect_modules() for the module's name.
Failed to build these modules:
crypt nis
running build_scripts
Checking setup.py leads to seeing python wants zlib 1.3.3, but I just tried to upgrade so it should be current.
Running tests as 3.4 works:
$ tox -e py34 py34: commands succeeded congratulations :)
What can be the issue here? Is there a way to reinstall python2.6 that won't error on zlib? Thank you

This is late, but if anyone else has a similar problem:
It seems that tox creates the virtualenv only once. If it did that, and you afterwards e.g. altered the requirements.txt file, you need to re-create it:
To force tox to recreate a (particular) virtual environment:
tox --recreate -e py27would trigger a complete reinstallation of the existing py27 environment (or create it afresh if it doesn’t exist).
