Hallo liebe Pythonfreunde,

ich versuche das Paket Levenshtein (String-Vergleiche...) zu installieren.

Folgendes habe ich probiert:

Wechsel in den Ordner des Packages und dann:
"sudo python setup.py install"

Da bekomme ich diesen Fehler:

Ebenso wenn ich eingebe
"sudo easy_install python-Levenshtein"

bekomme ich:

Was kann ich tun, um Levenshtein erfolgreich zu installieren?


Vielen Dank,

Apotekarnes

@Apotekarnes: Das Paket enthält offenbar C-Quelltext und braucht deshalb einen C-Compiler um installiert werden zu können.

Wenn gcc die Datei Python.h nicht findet, dann vermutlich, weil die Python-Sources nicht installiert sind. Die kannst du über den Package-Manager deiner Linux (oder BSD, oder ...) - Distribution nachinstallieren.

Danke für eure beiden guten Antworten!

Nachdem ich im Paket-Manager von Ubuntu keine "Python-Sources" finden konnte, habe ich nach kurzem Googlen "Python-dev" installiert, was hinreichend war. Danach war Python.h vorhanden und Levenshtein konnte installiert werden.

Danke!

Hallo,

das Paket heißt auch unter Ubuntu - wenig verwunderlich - "python-dev" (http://packages.ubuntu.com/search?keywo ... ection=all. Bzw. für Python3 "python3-dev".

Bei Ubuntu / Debian haben die Entwicklerpakete, die du zum Kompilieren braucht, üblicherweise das Suffix "-dev".
