ImportError: No module named _math #2299

@dbl001 Unfortunately, we haven't had much success building on Anaconda. We don't officially support it. If you figure this out, please let us know. |
|
Will it build if I run python in the virtual environment (and skip Anaconda)? |
|
I hope so! 😄 |
|
Can you point me to instructions for building / install nupic in the virtual env? |
|
Look here, specifically use the https://github.com/numenta/nupic-linux64 or https://github.com/numenta/nupic-darwin64 repos, which use virtual env (see their READMEs). |

@dbl001 Have you tried CLang? |

Is this relevant? -o build/temp.macosx-10.5-x86_64-2.7/extensions/py_support/NumpyVector.o http://stackoverflow.com/questions/24243176/how-to-specify-target-mac-os-x-version-using-qmake http://stackoverflow.com/questions/24243176/how-to-specify-target-mac-os-x-version-using-qmake

I think I remember having a similar problem a long time ago when I had a Matt Taylor On Fri, Jul 10, 2015 at 9:42 AM, dbl001 notifications@github.com wrote:
