Problems installing Numpy in Virtualenv

Question

I have numpy installed globally (I think via Django) but I'm trying to install it within a virtualenv. When I run

pip install numpy

(within my virtualenv), it gets stuck at Running setup.py install for numpy.

Any ideas on how I can fix this? If you require any additional information just let me know and I'll post it.

Answer 1

Googling it comes mainly to specific solution taking about presence of gcc and other packages.

Check if gcc is installed else install it:

sudo apt-get install gcc

Also you need to install those packages:

sudo apt-get install build-essential python-dev
