NumPy 64bit fail to install with pip on Windows wi

Question

pip install "c:\temp\numpy-1.10.4+mkl-cp35-cp35m-wi
n_amd64.whl"

returns the following error:

numpy-1.10.4+mkl-cp35-cp35m-win_amd64.whl is not a supported wheel on this pl atform.

OS: Windows 7 pro 64bit
pip version: 8.1.0
Python: 3.5.1 64bit

NumPy wheel file: numpy-1.10.4+mkl-cp35-cp35m-win_amd64.whl
from http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy

So, all the version are aligned I think. Or Python 3.5.1 is too new for cp35?

Note. On another PC with exactly the same versions but Windows 10 it works.

Thanks,
Alessandro

Answer 1

I looked into req_install.py and wheel.py files of pip (in [python path]/lib/site-packages/pip) and I found where is done the check of the wheel. It split the file name to obtain "tags" from it for comparison with supported tags.

I removed the environment variable "PLATFORM" (it is not present in the other machine) and then it worked.
