error: Microsoft Visual C++ 10.0 is required
I get an error when installing numpy with pip. Some packages require C / C ++ compilation. The cause of the error is that the compiler is not installed.
pip install numpy
(abridgement)
error: Microsoft Visual C++ 10.0 is required (Unable to find vcvarsall.bat).
If I install the compiler, the error disappears, Installing a C / C ++ compiler that is not directly related to Python is a hassle. Fortunately, there are sites that distribute binaries compiled for Windows.
Download the whl format file from here. Specify the file downloaded with pip and install it.
pip install numpy-1.9.2+mkl-cp34-none-win32.whl
