我在互联网上搜索了magic在 Windows 10 64 位中正确导入的解决方案。我找到了这个，但我不明白解决方案。

  1. 它说将两个 DLL 复制到操作系统中的指定路径中。

  2. 下面的命令是什么意思？

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

解决方案是1 + 2的组合吗？还是只有 1 个？我已经完成了 1. 仍然出现错误。（第一个错误已解决）

>>> 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

我得到的第二个错误

我认为您已成功完成第 1 步。在第 2 步中，将您的 magic.mgc 文件（通过克隆libmagicwin64获得）保存在 python 脚本可访问的位置（在以下情况下为C:\Programs\libmagicwin64\文件夹）。然后你可以像这样使用......

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