After today's python updates, I'm getting an error in calibre converting to .mobi. I have the python2-cssutils package installed, am I missing another package?
File "/usr/lib/python2.7/site-packages/lxml/cssselect.py", line 18, in <module>
raise ImportError('cssselect seems not to be installed.

Well, installed the python2-cssselect package from the AUR, now getting an error from the .py file that's calling cssselect.py
File "/usr/lib/calibre/calibre/ebooks/oeb/stylizer.py", line 23, in <module>
from lxml.cssselect import css_to_xpath, ExpressionError, SelectorSyntaxError
ImportError: cannot import name css_to_xpath

Maybe you should file a bug report?

Maybe. I usually try to figure out what's going on before filing a bug report. I would hate to do that when it was caused by something stupid I did. I'm going to keep looking, if I don't find anything, I'll file one.

OK, found it. Downgrading python2-lxml fixed it; it appears that the cssselect.py in this package was converted from a full blown module to a wrapper for CSSSelect in the upgrade to 3.0. As such, this is mostly an upstream bug in Calibre. On the other hand, python2-lxml now would depend on CSSSelect for this wrapper to function, which is in the AUR. I'll file the appropriate bug both places.

Could you post links here when you do to enable others to locate the bugs easily? Thanks.

Sure. Looks like I had somehow missed an already filed bug here:
https://bugs.archlinux.org/task/31857
But calibre doesn't work with lxml 3.0 even with the right packages, that bug is here:

Calibre will only support their own binaries, which include the necessary python libs. Bug report filed for Arch's Calibre package:

For a temp solution I recommend changing line 23 in /usr/lib/calibre/calibre/ebooks/oeb/stylizer.py
from:
from lxml.cssselect import css_to_xpath, ExpressionError, SelectorSyntaxError
to:
from cssselect import GenericTranslator
Patch is short so I'm posting it here:

b3niup, you would want to leave the ExpressionError and SelectorSyntaxError in the import statement as well.
If you check the bug reports, you'll see that I posted a sed statement to add to the PKGBUILD that does exactly that. This fixes the bug in Calibre itself, but still relies on a package from the AUR, which is a bug in itself.

OK, it appears that 0.9.3 did fix Calibre's issue, so now all that people need to do to get Calibre running right is installs python2-cssselect from the AUR.

python2-cssselect now seems to be in extra but still needs to be installed manually.
