在 Google Colab 中尝试 install/use Python-Magic 时出错

Question

我正在尝试在 Colab 中安装 python-magic。这里是图书馆的Githubhttps://github.com/ahupp/python-magic#dependencies

当我尝试时：

!pip install python-magic
import magic

结果是

---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-44-1461204615fc> in <module>()
      1 get_ipython().system('pip install python-magic')
----> 2 import magic

/usr/local/lib/python3.6/dist-packages/magic.py in <module>()
    179 if not libmagic or not libmagic._name:
    180     # It is better to raise an ImportError since we are importing magic module
--> 181     raise ImportError('failed to find libmagic.  Check your installation')
    182 
    183 magic_t = ctypes.c_void_p

ImportError: failed to find libmagic.  Check your installation

---------------------------------------------------------------------------
NOTE: If your import is failing due to a missing package, you can
manually install dependencies using either !pip or !apt.

我已经尝试了所有可能的解决方案

这个 SO post 说 Exception Value:failed to find libmagic. Check your installation in windows 7

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. https://github.com/ahupp/python-magic#dependencies

但是不再列出依赖项。

我也试过了

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

和

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

来自这个 SO post

pip installing eyeD3 module. Failed to find libmagic

我试过了

pip install python-magic-bin==0.4.14

我也试过了

!brew install libmagic

但 Colab 似乎无法识别 brew

Answer 1

在Colab上安装Libmagic的方式如下：

!apt-get install libmagic-dev
!pip install python-magic

那么，导入就没有问题了：

import magic
