Here is my traceback

Answer 1

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

Answer 2

Your multiuploader form uses python-magic library possibly for filetype identification. However you probably do not have all the missing dependencies installed. Please install the missing dependencies.

Answer 3

As per the documentation (https://pypi.org/project/python-magic/) 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.

Answer 4

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

Answer 5

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

Answer 6

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: https://www.cygwin.com/
2. Install cygwin.
3. Enter the path of cygwin and copy cygwin1.dll/cyggcc_s-1.dll/cygmagic-1.dll/cygz.dll to C:\Windows\SysWOW64.

Answer 7

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 !!!

Answer 8

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')
