我正在尝试在 Colab 中安装 python-magic。这是库的 Github https://github.com/ahupp/python-magic#dependencies

当我尝试：

!pip install python-magic
import magic

这导致

---------------------------------------------------------------------------
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

这篇 SO 帖子说 Exception Value:failed to find libmagic。检查您在 Windows 7 中的安装

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

但是不再列出依赖项。

我也试过

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

从这个 SO 帖子

pip 安装 eyeD3 模块。找不到 libmagic

我试过了

pip install python-magic-bin==0.4.14

我也试过

!brew install libmagic

但 Colab 似乎不承认brew

在 Colab 上安装 Libmagic 的方式如下：

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

然后，您可以毫无问题地导入它：

import magic
