magic.MagicException: None

[francesco1119]

I'm using your library for my Python3 script. It works very well on Windows 10 Linux bash but when I switch back to Windows 10 Command Prompt the same script is not working.

Traceback (most recent call last):
  File "Pukeko.py", line 159, in <module>
    dirlist(path)
  File "Pukeko.py", line 155, in dirlist
    dirlist(i)
  File "Pukeko.py", line 151, in dirlist
    LetsTry(i)
  File "Pukeko.py", line 127, in LetsTry
    elif "text" in magic.from_file(p, mime=True):
  File "C:\Users\franc\Miniconda3\lib\site-packages\python_magic-0.4.15-py3.6.egg\magic.py", line 135, in from_file

magic.MagicException: None

I think this is mainly due to the fact that on Windows I'm using Miniconda.

Is there any workaround?

This probably means it can't find the magic file that defines all the file types. Try passing it in explicitly to the constructor of magic.Magic.

i have the same problem When I indicate explicitly: i get correct output:

but in Django project the same code:

it's just txt file

@polnikov can you use procmon to look at what is being opened (both the magic DLL and the magic DB file) in those two examples? My guess is that one or both are different due to slightly different paths.
