I'm a newbie to web2py, and to web frameworks like it in general really.

I just installed web2py (apt-get install web2py), and I'm just trying to get through the tutorial (http://web2py.com/books/default/chapter/29/2), but I'm already running into problems.

I try to run web2py -S welcome, but I get the following error:

os.mkdir(folder)

Can anyone tell me what's going on here?

Run web2py -S welcome
as sudo web2py -S welcome
so the program can create the files it needs. I think its just a config file, you probably wont need to run it as root again after that.

That's weird. That seems like a bug to me. There shouldn't be a reason that root is needed to create an application.

PS It did work.
