Webmananager: bottle module not mentioned in howto - by: mlarsson

Hi!
I'm trying to get the webmanager to work. I follow the instructions on
indilib.org/support/tutorials/162-indi-web-manager.html

But when trying to maually start it, I get:

pi@raspberry:~/servermanager$ python drivermanager.py
Traceback (most recent call last):
File "drivermanager.py", line 3, in <module>
from bottle import Bottle, run, template, static_file, request
ImportError: No module named bottle

However, it's easyli installed with

pi@raspberry:~/servermanager$ sudo pip install bottle
The directory '/home/pi/.cache/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

I guess this should be included in the instructions?u

The warnings I get, about the /home/pi/.cache/pi - what does that mean? There is no such directory... and .cache is owned by pi.
