Exception Value: Failed to Find Libmagic. Check Your Installation in Windows 7

Go here and then:

For Windoes 32bit, download the file "python_magic_bin-0.4.14-py2.py3-none-win32.whl" and run

pip install python_magic_bin-0.4.14-py2.py3-none-win32.whl

For Windows 64bit, download "python_magic_bin-0.4.14-py2.py3-none-win_amd64.whl" and run

pip install python_magic_bin-0.4.14-py2.py3-none-win_amd64.whl

now python-magic works

EDIT: As suggested in the comments, this also works:

pip install python-magic-bin==0.4.14

As per the documentation () you have to install libmagic.

For Windows OS, you can do it by run the bellow command:

pip install python-magic-bin

And for Ubuntu based OS, you have to it by the bellow command:

sudo apt-get install libmagic1

From, your exception it is easy to say that, you are using Windows OS, so you have install it by the first command.

As per the documentation the current version of python-magic is 0.4.15

• You can install the latest released version of python-magic through:

  pip install python-magic
  

• This will install python-magic-0.4.15 as follows:

  C:\Users\username>pip install python-magic
  Collecting python-magic

  Installing collected packages: python-magic

• In the (Windows) documentation it is mentioned:

You'll need DLLs for libmagic. @julian-r has uploaded a version of this project that includes binaries to pypi:

• You can install the python-magic-bin 0.4.14 through:

  pip install python-magic-bin==0.4.14
  

• This will install python-magic-bin 0.4.14 as follows:

Install cygwin. Then move 'C:\cygwin64\bin\cygmagic-1.dll' to 'C:\Windows\System32\magic1.dll'.

1. Download cygwin. The version of cygwin must as same as python.(exp: Although your OS is Win7 x64, you still should download 32 bit cygwin because your python is 32 bit). link:
2. Install cygwin.
3. Enter the path of cygwin and copy to C:\Windows\SysWOW64.

I was going carzy with this issue. But finally got a solution to it

Steps

1. Uninstall all magic libraries from you system (as you may have tried installing tons of garbage by this time)
2. Make sure you are running a python 64 bit version
3. Install pip install python-magic-win64==0.4.13
4. very important step, change your import statement to from winmagic import magic

Enjoy !!!

If your target platform supports the file command with certain extensions (available on macOS, *BSD and most Linux variants), you can use the following wrapper that does not require libmagic nor other dependencies:

import contextlib
import subprocess

def file_proc():
    args = [
        '/usr/bin/file',
        '--brief',
        '-E',
        '--no-dereference',
        '--no-buffer',
        '--preserve-date',
        '-00',
        '--mime-type',
        '--files-from', '-'
    ]

    with contextlib.ExitStack() as stack:
        proc = subprocess.Popen(args, bufsize=0, stdin=subprocess.PIPE, stdout=subprocess.PIPE, preexec_fn=None, text=True)
        stack.callback(proc.kill)

        while True:
            file_path = yield
            proc.stdin.write(file_path + '\n')
            proc.stdin.flush()

            file_type = ''
            while (c := proc.stdout.read(1)) != '\0':
                file_type += c

            yield file_type.splitlines()[0]


@contextlib.contextmanager
def file_typer():
    proc = file_proc()
    proc.send(None)

    def getter(path):
        posix_type = proc.send(path.as_posix())
        proc.send(None)
        return posix_type

    with contextlib.closing(proc):
        yield getter
        

with file_typer() as typer:
  typer('/usr/bin/python')
