Pyrocket and Ubuntu

I have a great USB rocket launcher, it’s more useful than a computer mouse most of the time actually. I spotted a moth on the roof the other day, and hadn’t installed pyrocket on this computer yet.

A quick apt-get install pyrocket is all it takes to solve that though, right? No such luck.

Apparently, the quality control in the Ubuntu repos are such that this package has been broken for several months now, despite the dependency issue being fixed by an upstream fork.

So this is the error you get at the moment anyway:

Traceback (most recent call last):
  File "/usr/bin/pyrocket", line 17, in 
    from rocket_frontend import RocketWindow
  File "/usr/lib/pymodules/python2.7/", line 11, in <module>
    from rocket_webcam import VideoWindow
  File "/usr/lib/pymodules/python2.7/", line 2, in <module>
    from opencv import cv, highgui
ImportError: No module named opencv

The solution, beyond complaining about it, is to read the bug report here and do this:

git clone
cd pyrocket/src

But the moth had escaped by then.
