在Windows 64位上導入魔術問題

Question

我在互聯網上搜索了一種在Windows 10 64位中正確導入magic的解決方案。 我找到了 ，但是我不明白解決方案。

1. 它說將兩個DLL復制到OS中的指定路徑。

2. 以下命令是什么意思？

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

解決方案是1 + 2的組合嗎？ 還是只有1個？ 我已經完成了1.仍然出現錯誤。 （第一個錯誤已解決）

>>> 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

我得到的第二個錯誤

Answer 1

我認為您已經成功完成了步驟1。在第二步中， 將您的magic.mgc文件（通過克隆libmagicwin64獲得）放置在可由python腳本訪問的位置 （在以下情況下為C：\\ Programs \\ libmagicwin64 \\文件夾）。 那么你可以這樣使用...

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