Python Installing Cython & Numba but no vcvarsall.bat despite Visual C++ 2010 -
i use python 3.4
i try install cython , numba keep getting "unable find vcvarsall.bat".
i googled solution , found need microsoft visual c++ 2010 installed (for python 3.4).
so installed it.
and tried installing cython , numba ---> fail.
and must type "set vs90comntools=%vs100comntools%" in command prompt, did, c:\users\dorky>set vs90comntools=%vs100comntools%.
and tried installing cython , numba again ---> fail.
not enough that, went environment variables set vs90 vs100 thing manually.
and tried installing cython , numba again ---> fail.
so how can solve special "unable find vcvarsall.bat" problem?
what heck special vcvarsall.bat user must install microsoft's programs in order use it?
why not extract out vcvarsall.bat file independent file , copy&paste file or directory needs , not bother rest of software package?
why not python team extract out vcvarsall.bat , incorporate python packages whenever user installs python, he/she install vcvarsall.bat along way , python know file in case needing install cython or numba or other?
if you're using python.org version of python, there's easier way go things - grab packages you're interested in christoph gohlke's python extension packages windows repository. has large selection of scientific computing-based python modules, including cython
, numba
(you'll need numpy
- compiled intel's mkl - , llvmlite
- requires this - well). precompiled .whl
packages can installed up-to-date version of pip
. modules kept updated latest versions on pypi or other repositories.
this go-to site installing packages on windows, , if i'm looking isn't there, i'll install via pip
or package source.
