  <p>Basically, something about cached files,  a bunch of AttributeErrors from site.py and something about not having freetype or png. I tried to fix site.py, but it still doesn't work. I tried the .whl file from PyPi, and that doesn't work. I tried "pip install matplotlib --no-cache-dir", same thing. I tried manually downloading png and freetype, but I couldn't find them. Roughly the same thing happens with all the other libraries that I want to download: NumPy, SciPy, pandas. </p>
