When I'm trying to install matplotlib using pip it throw me exception:

In file included from /usr/include/numpy/ndarrayobject.h:26:0,
                 from src/file_compat.h:7,

If i understand it correctly the problem in numpy. I install it using this command:

pypy -m pip install git+https://bitbucket.org/pypy/numpy.git@pypy-4.0.1

My numpy version is 1.9.0. My version of pypy:

'2.7.10 (4.0.1+dfsg-1~ppa1~ubuntu15.04, Nov 20 2015, 19:34:27)\n[PyPy 4.0.1 with GCC 4.9.2]'

    Numpy is not compatible with PyPy (and neither is matplotlib). See [here](http://packages.pypy.org/) for the list of currently supported packages. – ali_m Feb 21 '16 at 14:32

    @ali_m incorrect. Numpy is compatible. – Qix - MONICA WAS MISTREATED Sep 07 '16 at 10:08

    @Qix Well, that comment was correct when I wrote it back in February. The situation seems to have improved a bit since then, in that it's now possible to install a full version of numpy using cpyext ([numpypy is far from complete](http://buildbot.pypy.org/numpy-status/latest.html)). [matplotlib still isn't officially supported](http://packages.pypy.org/##matplotlib) (although see [here](https://morepypy.blogspot.co.uk/2016/06/pypy2-v53-released-major-c-extension.html)). – ali_m Sep 20 '16 at 18:41

I succeed in install it. (But not perfect)

pypy7.3.3x64 ubuntu WSL

pypy3 -m pip install matplotlib==2.2

You may need to install some other packages.

Why 2.2

Why ipynb? Since GUI on WSL is not so easy. I managed to deal with CPython && matplotlib (By Xming), but not pypy3.

Now the newest is mpl==3.3.1, it could work, but with a lot of warning.

/lib/pypy3/lib_pypy/_functools.py:80: MatplotlibDeprecationWarning: print_svg() got unexpected keyword argument "orientation" which is no longer supported as of 3.3 and will become an error two minor releases later
  return self._func(*(self._args + fargs), **fkeywords)
/lib/pypy3/lib_pypy/_functools.py:80: MatplotlibDeprecationWarning: savefig() got unexpected keyword argument "orientation" which is no longer supported as of 3.3 and will become an error two minor releases later
  return self._func(*(self._args + fargs), **fkeywords)
/lib/pypy3/lib_pypy/_functools.py:80: MatplotlibDeprecationWarning: savefig() got unexpected keyword argument "dpi" which is no longer supported as of 3.3 and will become an error two minor releases later
  return self._func(*(self._args + fargs), **fkeywords)

The fix that worked for me:

sudo apt-get install pypy3-dev
