After a long investigation, I have found out that, in python-pyscss, there's the following code in scss/expression.py:
return String( six.u("%s(%s)" % (func_name, six.u(", ".join(rendered_args)))), quotes=None) If I remove the first six.u(), and the code becomes like this: return String( "%s(%s)" % (func_name, six.u(", ".join(rendered_args))), quotes=None) then everything works. Though this comes from a Debian specific patch for which I added the six.u() calls, to make it work in Python 3.2 in Wheezy. The original code is in fact: return String( u"%s(%s)" % (func_name, u", ".join(rendered_args)), quotes=None) So, could anyone help me fixing this? What's the way to make it always work? I wouldn't like to just drop Python 3.x support because of this... :( Cheers, Thomas Goirand (zigo) On 09/28/2014 12:38 AM, Thomas Goirand wrote: > Hi, > > When installing the Juno b3 version of Horizon, the package that I > maintain does the compressions, so that we can use the offline > compression mode, which offers better performances.
