[Health] Installing calendar module issue

[Federico Conforti]

Hi everybody,

I have already installed GNU Health with basic modules. The I used pip to install the calendar and succeeded in, but when I run the server the following lines appeared:

--------------------------------------------------------------

Any suggestion to fix it?

Bear in mind that I'm a newby, so it would be great if you send me all the lines to solve the problem.

Thanks in advance!
