Install matplotlib to pypy

Question

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,
                 from src/ft2font_wrapper.cpp:3:

   if (st == NPY_CPU_UNKNOWN_ENDIAN) {
             ^

   if (st != NPY_CPU_LITTLE) {
             ^
error: command 'cc' failed with exit status 1

----------------------------------------
Command "/usr/bin/pypy -u -c "import setuptools, tokenize;__file__='/tmp/pip-build-vGxrsz/matplotlib/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-oB9gVW-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /tmp/pip-build-vGxrsz/matplotlib

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

pypy -m pip install git+https://bitbucket.org/pypy/[email protected]

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 for the list of currently supported packages. — ali_m

@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). matplotlib still isn't officially supported (although see here). — ali_m

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)

Using WSLg in Windows 11 these days fixes the GUI issues with WSL2.

The fix that worked for me:

sudo apt-get install pypy3-dev

I also wanted to add that matplotlib version 3.5.2 has worked well for me, even on pypy3.10.

Not sure why this was downvoted, installing the pypy dev headers worked for me.
