magicexception：文件5.41仅支持版本16魔术文件，魔术.mgc是版本14

Question

当我运行python3.8 manage.py在我的django rest api上迁移时，我在虚拟环境上遇到了这个魔术版本的错误。

激活虚拟环境后，我已经完成了以下操作：

• pip3 install python-magic-升级

这是最后显示的。

magic.magicexception：b“文件5.41仅支持版本16魔术文件。

有几条错误，例如偏移错误，但由于堆栈上的字符限制，我已经取了一些错误并将其发布。

在这里需要帮助，因为我被困住了，无法继续前进。

问题与Python版本有关。如果您使用Python3.8生成MGC文件，则必须使用Python3.8加载此MGC文件。
