Numpy installation AWS EC2 Error

Question

I tried easy install and pip to install numpy on an EC2 micro instance. Didn't work.

I get:

RuntimeError: Broken toolchain: cannot link a simple C program

I tried virtualenv too, same story.
What am I doing wrong?

Answer 1

You probably don't have the development packages installed.

Amazon Linux run:

sudo yum groupinstall "Development Tools"

Ubuntu run:

sudo apt-get install packaging-dev

Answer 2

For simple testing, ssh into your instance

sudo yum install gcc
sudo pip install numpy

then go get yourself a coffee. Installed in about 3.5 mins.
