python - Installing a package into a virtual environment on Windows 7 -
i used programming on mac or linux box installing packages virtual environment relatively straightforward. unfortunately, not seem case windows. have been trying install lxml virtual environment on 64 bit windows 7 machine.
first used pip (my preferred tool):

c:\users\spearsc\appdata\local\temp\pip_build_spearsc\lxml storing debug log failure in c:\users\spearsc\pip\pip.log i have seen error before. think caused c compiler not beingness set. knew past experience fixing issue tremendous pain, decided seek method.
i went http://www.lfd.uci.edu/~gohlke/pythonlibs/ , downloaded exe file lxml. activated virtual environment , ran executable in it. library installed globally, not wanted, uninstalled lxml.
for 3rd attempt, activated virtual environment , used easy_install install lxml. 1 time again, bundle installed globally! uninstalled lxml pip.
i disappointed. going have install packages globally , forget using virtual environments? of solutions have seen on web seem outdated.
hm, when utilize virtual environment's easy_install, installs in virtual env, not globally.
but aside, way go create wheel .exe, , pip install that. (wheel/.whl new standard replacing .egg format. see pep 427 or readthedocs, among others.)
do following:
pip install wheel download .exe wininst2wheel.exe <downloaded .exe file> pip install <created .whl file> python windows virtualenv
