AttributeError: 'module' object has no attribute 'match_hostname'

[Vayel]

On Fedora 20, with Python 2.7, I runned the test command of that Makefile and got the following error:

$ make img
scons img
scons: Reading SConscript files ...
AttributeError: 'module' object has no attribute 'match_hostname':

make: *** [img] Error 2

Before that, I did:

git clone https://github.com/crossbario/crossbarwww
git clone https://github.com/crossbario/crossbar.wiki.git

cd crossbarwww
pew new crossbarwww # Create a virtualenv with Python 2.7

(crossbarwww) [vincent@vincent crossbarwww]$ make requirements
(crossbarwww) [vincent@vincent crossbarwww]$ pip install --egg scons

Thanks.

What Python version? The match_hostname monkey patching was added because of strict hostname stuff in Python 2.7.9 ...

[Vayel]

Python 2.7.5

I've pushed Taschenmesser 0.1.7 to PyPI .. this should fix the error you see. Could you retry?

[Vayel]

The error disapeared but I got this one:

(crossbarwww) [vincent@vincent crossbarwww]$ make img

Probably more related to crossbarwww than to this repo.

Taschenmesser: Inkscape executable not found - SVG to PNG conversion won't be available.

[oberstet]

We should handle that better of course .. but you need to have Inkscape installed.

It works. Thanks.
