Issue with installation on Ubuntu 18.04

[TitouanTyack]

Hello,

I wanted to test crazyswarm on a fresh Ubuntu 18.04 install.
I followed the "Physical Robots and Simulation" docs : https://crazyswarm.readthedocs.io/en/latest/installation.html
When I try to install the dependencies, it returns me this error :

Do you have any idea of what can I do ?

Thanks for you help

Use export CSW_PYTHON=python rather than export CSW_PYTHON=python2.
