#Python install matplotlib cygwin install

IвЂ™m forced to use a win7 host for something (IвЂ™ve been a desktop linux-only for about 15 years). Wow, did this posting save me a lot of time! Thank you, thank you, thank you.

It has something to do with my libfreetype IвЂ™ve noticed. I gave up for a while and used my vagrant box. cygwin, matplotlib, numpy, python, scipyДЄh man I wish it wouldвЂ™ve notified me that you replied.To do this, locate the file `matplotlibrc` and change `backend : agg` to `backend : tkagg`. To fix that, you need to have `XWinServer` running and should configure matplotlib to use `tkagg` backend. I was able to get it to install using `pip -v install scipy=0.15.1`.ДЄfter installation, you may notice that you canвЂ™t plot stuff using mathplotlibвЂ™s `pyplot` module. The most important thing is that as of SciPy v 0.16.1, there seems to be some error in SciPyвЂ™s C files that prevents compilation and installation. Running `pip -v install numpy` and `pip -v installВ matplotlib` should get you those packages without much headache. The dependencies that pip complains about are straightforward (just mark them for installation in CygwinвЂ™s installer). You also need to have `gcc-fortran`, `python-gtk2`, `tcl-tk`, `libpng`, `pkg-config` and a bunch of other stuff (that pip installer complains about) installed. Then using the `easy_install3 pip` command you can install pip.ДЄfter that, you need to have `liblapack-devel` and `libopenblas` installed via CygwinвЂ™s package manager (SciPy depends on them). To install pip, you need to haveВ `python3-setuptools`installed. The whole thing took a few hours to figure out thanks to crappy bundled packages that pip fetches and lack of consistency between helps available online. Today I tried installing these modules under Cygwin with pip.
