First, please bear with me. I have hard time telling others my problem and this is a long thread... I am using pythonbrew to run multiple versions of python in Ubuntu 10.10. For installing pythonbrew and how it works, please refers to this link below http://www.howopensource.com/2011/0...manage-different-versions-of-python-in-linux/ After reading a couple stackoverflow threads, I finally found the file called Setup under this directory: ~/.pythonbrew/pythons/Python-2.7.1/lib/python2.7/config In this Setup file I see # Andrew Kuchling's zlib module. # This require zlib 1.1.3 (or later). # See http://www.gzip.org/zlib/ # zlib zlibmodule.c -I$(prefix)/include -L$(exec_prefix)/lib -lz I uncommented the last line, then I ran python -v again. However, I received the same error when I tried import zlib, so I guess I have to do something to install zlib into the lib. But I am clueless about what I need to do. Can someone please direct me in the right direction??? Thank you very much! I am doing this because I want to use different version of python in different virtualenv I created. When I did virtualenv -p python2.7 I received no module named zlib. jwxie518@jwxie518-P5E-VM-DO:~$ virtualenv -p python2.7 --no-site-packages testenv Running virtualenv with interpreter /home/jwxie518/.pythonbrew/pythons/Python-2.7.1/bin/python2.7 Traceback (most recent call last): File "/usr/local/lib/python2.6/dist-packages/virtualenv.py", line 17, in <module> import zlib ImportError: No module named zlib EDIT I have to install 2.7.1 by appending --force. I am developing Django, and I need some of these missing modules, for example sqlite3, and to create my virtualenv I definitely need zlib. If I just use the system default (2.6.6), I have no problem. To do this with system default, all I need to do is virtualenv --no-site-packages testenv Thanks! (2nd edit) I installed 3.2 also and I tested it without problem, so I guess my problem comes down to how to install the missing module(s). jwxie518@jwxie518-P5E-VM-DO:~$ virtualenv -p python3.2 testenv Running virtualenv with interpreter /home/jwxie518/.pythonbrew/pythons/Python-3.2/bin/python3.2 New python executable in testenv/bin/python3.2 Also creating executable in testenv/bin/python Installing distribute..................................................................................................................................................................................................................................................................................................................................done.
