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.

您的 multiuploader 表单可能使用 python-magic 库来识别文件类型。但是，您可能没有安装所有缺少的依赖项。请安装缺少的依赖项。

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

安装 cygwin。然后将“C:\cygwin64\bin\cygmagic-1.dll”移动到“C:\Windows\System32\magic1.dll”。

去这里然后：

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

对于Windows 32bit，下载文件“python_magic_bin-0.4.14-py2.py3-none-win32.whl”并运行

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

对于Windows 64 位，下载“python_magic_bin-0.4.14-py2.py3-none-win_amd64.whl”并运行

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

now python-magicworks

现在python-magic有效

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

编辑：正如评论中所建议的，这也有效：

pip install python-magic-bin==0.4.14

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.

1. 下载 cygwin。cygwin 的版本必须和python 一样。（说明：虽然你的操作系统是Win7 x64，但你还是应该下载32 位的cygwin，因为你的python 是32 位的）。链接：https: //www.cygwin.com/
2. 安装 cygwin。
3. 输入cygwin的路径，将cygwin1.dll/cyggcc_s-1.dll/cygmagic-1.dll/cygz.dll复制到C:\Windows\SysWOW64。
