问题
I'm trying to install pymvpa2 in Python 2.7. using pip. I successfully installed other required modules, but I can't install pymvpa2 (I use Python 2.7 and Windows 10). Also, I downloaded swig, but I keep getting the same error message:
C:\WINDOWS\system32>cd "C:\Python27\Scripts"
C:\Python27\Scripts>pip install pymvpa2
Collecting pymvpa2
Using cached pymvpa2-2.6.1.tar.gz
Complete output from command python setup.py egg_info:

Command "python setup.py egg_info" failed with error code 1 in c:\users\MYCOM\appdata\local\temp\pip-build-uiyfnt\pymvpa2\
Thank you in advance for helping me out!!

pip complains about not finding "swig.exe". Have you checked that you can execute "swig.exe" from the terminal? Simply typing swig or swig.exe should help you find this out. When a command-line program is installed successfully, you can simply type its name in a terminal and it should start.
If swig is not available by this methods, check their special page to get you started on windows: http://www.swig.org/Doc3.0/Windows.html
