Error Installing Pymvpa2

I'm getting the following error when I try to install using pip install for PyMVPA2 for Python. I have installed other libraries without any problems before. I would appreciate if

Solution 1:

As the error states you either don't have swig installed or it is not on your path. You are obviously on Windows so you need to download the swig executable from the swig website - download the latest windows package and either unzip it to a directory on your existing path or to a new directory and add it to your path. Easiest, of course, is to unzip it to a new directory and then run your pip command in that directory.

• What is swig anyway? Swig parses the interface definitions of code written in C/C++ and can output 'glue code' to allow code written in Python & a pile, currently 22, of other programming or scripting languages to use the C/C++ code transparently. Swig is free, open source and compatible with both open source and commercial use.

• Should I keep it to hand? In most cases that I know of in python swig is only invoked during the installation or setup phase but since that setup phase will be used every time that any package built with swig is installed or upgraded there is no reason to get rid of it and quite a lot of reasons to have it somewhere on your path.

Solution 2:

sudo apt-get remove swig
sudo apt-get install swig3.0
sudo ln -s /usr/bin/swig3.0 /usr/bin/swig

and then

pip install pymvpa2
