I'm not sure if this is my own stupidity, related to #283, or something I've ended up doing myself by accident.

I'm working on developing a mkdocs theme, and mkdocs build and mkdocs build --clean both run without any issues.

However, if I try and mkdocs serve then I get hit by an error.

Traceback (most recent call last):

My mkdocs.yml file is simple, and I don't think it is the actual cause, but it might be in my own inept way:

site_name: Face Theme
theme_dir: face
theme: face
use_directory_urls: true
repo_url: https://bitbucket.org/shakna-israel/face
dev_addr: 0.0.0.0:8000

Yup, that looks like a bug and not your fault. I'll need to take a look further to see what is up.

Sorry, should have included a few other things:

Python is 2.7.3
Pip is 6.0.8

And pip freeze gives:

argh==0.26.1
ghp-import==0.4.1
Jinja2==2.7.3
Markdown==2.4.1
MarkupSafe==0.23
mkdocs==0.11.1
pathtools==0.1.2
PyYAML==3.11
watchdog==0.8.3

This is all running on a Raspberry Pi B+, running Raspbian Debian 7.8 (wheezy)

Thanks - travelling at the moment but should get to this in a few days.

I think something funky is happening when mkdocs tries to split the host and port at the colon(serve.py, Line 107).

With some experimentation I got this:

File "/home/pi/.virtualenvs/necro/local/lib/python2.7/site-packages/mkdocs/serve.py", line 104, in serve
    host, port = config['dev_addr'].split(':', 1)
AttributeError: 'bool' object has no attribute 'split'

Unfortunately, I need mkdocs to serve out to a IP, and not the localhost, so looks like I'll be stuck building and serving for a while... Because I have no idea why split isn't working.

How did you resolve your previous error?

I can't see any way that dev_addr would become a boolean, have you changed the code at all? Can I see your latest config?

Seems that using mkvirtualenv meant that mkdocs looked for the "face" theme directory inside mkdocs own theme folder:

OSError: [Errno 2] No such file or directory: '/home/pi/.virtualenvs/face/local/lib/python2.7/site-packages/mkdocs/themes/face'

So I tried to isolate if that was the main error, by dropping the theme lines from my config, and specifying dev_addr from the commandline instead:

site_name: Face Theme
use_directory_urls: true
repo_url: https://bitbucket.org/shakna-israel/face

So, to run, I ran this command:

mkdocs serve --dev-addr 192.168.1.2:8000

And instead got this traceback:

I believe split can return the boolean error if it's not working on a string.

I see, interesting. Thanks. This is an odd one, but I have an idea - will look into it.
