Errore Funnelweb, impossibile importare OrderedDict

Question

Sto cercando di importare alcune pagine statiche da un sito utilizzando il componente aggiuntivo funnelweb per plone. Ecco cosa scrivo: bin/funnelweb --crawler:url=http://wiki.scandiatransplant.com --crawler:max=50 --ploneupload=http://admin:admin@localhost:8080/TestPage.

ottengo questo errore:

ImportError: cannot import name OrderedDict 

La piena traceback viene aggiunto sotto. Qualcuno sa come risolvere questo?

    ImportError: cannot import name OrderedDict 

Answer 1

OrderedDict è una nuova classe aggiunta a Python 2.7, in modo che manca nel vostro caso.

È possibile installare un backport:

pip install ordereddict 

o aggiungere che, come una dipendenza nella vostra buildout, e modificare Plone/buildout-cache/eggs/transmogrify.webcrawler-1.2.1-py2.6.egg/transmogrify/webcrawler/webcrawler.py la linea 21 per cambiare l'importazione da:

from collections import OrderedDict 

a

try: 
    from collections import OrderedDict 
except ImportError: 
    # python 2.6 or earlier, use backport 
    from ordereddict import OrderedDict 

Ho archiviato un problema nello funnelweb issue tracker per richiedere che questo venga aggiunto a una versione futura del pacchetto, vedere issue 22.
