篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了python递归解压文件夹中所有压缩包相关的知识,希望对你有一定的参考价值。

1. 简述

    递归解压文件夹中的所有压缩包到指定文件夹,方便快速搜索文件和整理移动文件。

2. 环境配置

    python解压rar文件需要安装依赖库 (python-unrar

    Windows:

  1. 在 RARLab 官方下载安装库文件 http://www.rarlab.com/rar/UnRARDLL.exe
  2. 默认路径伪 C:\\Program Files (x86)\\UnrarDLL\\
  3. 添加环境变量 UNRAR_LIB_PATH 键值 C:\\Program Files (x86)\\UnrarDLL\\x64\\UnRAR64.dll,如果是32位就是 C:\\Program Files (x86)\\UnrarDLL\\UnRAR.dll

    Linux:

  1. 下载库文件 https://www.rarlab.com/rar/unrarsrc-5.6.8.tar.gz
  2. $ make lib
    $ make install-lib
  3. 添加环境变量  export UNRAR_LIB_PATH=/usr/lib/libunrar.so

3. 实现

    代码实现
