XML einlesen

Ich vermute mal er versucht die falsche libxml2.so.2 zu laden. Was gibt er aus wenn du ``ldd /home/mit/programs/python/lib/python2.6/site-packages/lxml-2.2.6-py2.6-linux-x86_64.egg/lxml/etree.so`` eingibst?

Ich glaube du hast recht, aber leider weiss ich nicht wie man es beheben könnte.

kann es sein, dass der Dateiname im paket genutzt wird - also xml.py ?

Aber ich bekomme den Fehler mit nur den import Teil:

Was könnte der Fehler sein?

mkesper · Dienstag 18. Mai 2010, 12:06

Ist lxml nicht in deiner Paketverwaltung verfügbar?

mit · Dienstag 18. Mai 2010, 12:52

Leider arbeite ich an einem PC mit Cent OS 5.2 wo Python 2.4 installiert ist und ich habe kein Root-Zugang. Deshalb habe ich Python in mein Home Verzeichnis installiert. Alles funktioniert gut nur lxml bekomme ich nicht zum laufen.

BlackJack · Dienstag 18. Mai 2010, 14:16

@mit: Stimmen denn die Komponenten bezüglich der "Bitanzahl" überein? Also ist alles 64-Bit-Software? Also Python und die `libxml`? Denn `lxml` scheint es in diesem Fall zu sein.

Wie könnte man diesen Fehler beseitigen?
