在Raspberry Pi上安装PayPalRESTSDK时出错

Question

I'm trying to install the paypalrestsdk on a Raspberry Pi but I'm getting a huge error list:

$ pip install paypalrestsdk

This continues for a while so I've withheld the later bits.

Will paypalrestsdk run on a raspberry pi and what do I need to do to facilitate it?

Answer 1

@Cdarke has identified the issue correctly above but upgrading the Rapsberry Pi to 2.7.11 took some time. Here is a good tutorial
