pip10 breaks pybind11

[ddu1]

After upgrading to pip10, the python build will throw the following error:

python/fastText/pybind/fasttext_pybind.cc:13:31: fatal error: pybind11/pybind11.h: No such file or directory

pip can no longer find the includes of pybind11.
The issue is really a pybind11 issue. See the discussion at pybind/pybind11#1174

Hi @ddu1,

Thank you for reporting this issue.

Does using the latest version of pybind11 fixes the issue (c.f. #488)?

Best,
Edouard

@EdouardGrave,
Yes, as mentioned in #488, the fix 060936f of pybind11 solves the issue.
However before the next release of pybind11, I would simply change setup.py a bit,

install_requires=["pybind11>=2.2", "setuptools >= 0.7.0", "numpy", "pip>=9,<10" ]
