Install numpy from

(I looked through many answers here, but didn’t answer or didn’t answer my question).

I am using numpy + scipy + matplotlib for Mac OSX 10.8.5. I have numpy 1.6.1 on my machine and using python 2.7.5 in /System/Library/Frameworks/Python.framework/Versions/2.7/ . I have been working with this configuration for several months with Idle or command line.

I just upgraded to matplotlib 1.3.1 from a .dmg file in Sourceforge. Installation worked fine, and I see the correct version in matplotlib.__version__ . However, I cannot use it because it claims that I need numpy 1.7 or higher. So I downloaded the numpy-1.8.0 dmg file from Sourceforge and installed it using the Mac installer. The installer claims to have done it right, but numpy.__version__ is still 1.6.1 !!! I did the installation several times (each time successfully according to the Mac installer) with the same result.

I had no problems updating matplotlib to 1.3.1 and scipy to 0.13 using their .dmg files in Sourceforge. I do not understand why numpy should not be installed the same way. I had to update it the same way as in the past, but I do not remember.

I am running Python from Idle, as well as from the command line and don’t want to switch to another distribution such as Macports, etc. I have been using Python this way for 4 years and don't understand why numpy is not updating. Thanks for any help.

Three solutions, one of which is indicated in my comment, but the easiest way is to change your PYTHONPATH . At the command line:

 export PYTHONPATH=/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/:$PYTHONPATH

To make the change permanent, put this line in your

 ~/.bashrc

file.

From my comment:
I'm not sure how dangerous this is, but just move the installation according to your others, you can try

 mv /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/n‌​umpy/ /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/n‌​umpy_old/ cp /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/nump‌​‌​y/ /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/n‌​umpy/

Finally, you can try using pip to install numpy. To find out where pip installed, type this in the terminal:

 which pip

If you want it to be ( /Library/... ), then all you have to do is

 pip install numpy
