Problèmes d'importation de magie sous Windows 64 bits

Question

J'ai cherché sur Internet une solution pour importer correctement magic dans Windows 10 64 bits. J'ai trouvé this, mais je ne comprends pas la solution.

1. Il est indiqué de copier deux DLL dans le chemin spécifié dans le système d'exploitation.

2. Que signifie la commande ci-dessous?

   file_magic = magic.Magic(magic_file="c:\path\to\magic.mgc") 
   

La solution est la combinaison de 1 + 2? Ou juste 1? J'ai fait 1. Toujours avoir une erreur. (La 1ère erreur est résolu)

>>> import magic 
Traceback (most recent call last): 
    File "<stdin>", line 1, in <module> 
    File "C:\Python27\lib\site-packages\magic.py", line 176, in <modu 
    raise ImportError('failed to find libmagic. Check your install 
ImportError: failed to find libmagic. Check your installation 

Erreur Deuxièmement, je reçois

Answer 1

Je pense que vous avez terminé avec succès l'étape 1. 2ème étape garder votre fichier magic.mgc (obtenu par clonage de libmagicwin64) quelque part accessible par le script python (dans le cas ci-dessous dossier C: \ Programmes \ libmagicwin64 \). alors vous pouvez utiliser comme ça ...

>>> import magic 
>>> file_magic = magic.Magic(magic_file="C:\Programs\libmagicwin64\magic.mgc") 
>>> print(file_magic.from_file("D:\Work Folder\mcabcaaug2016.pdf"))
