Python之pip图形化（GUI界面）辅助管理工具

Python之pip图形化（GUI界面）辅助管理工具

pip 是 Python 的包管理工具，用于安装、管理、更新和卸载 Python 包（模块）。用于第三方库的安装和管理过程，是 Python 开发中不可或缺的工具。

包的安装、更新、卸载，查看，特别是当用户安装有多个版本的Python时，为特定版本进行这些操作。还可以使用镜像加速安装。

默认情况下，pip 会从 PyPI 下载包。如果你在中国大陆，可能会因为网络问题导致下载速度较慢。可以设置使用国内的镜像源。

有关详情可见：https://blog.csdn.net/cnds123/article/details/104393385

对于新手而言，还是比较麻烦的。

为此，提供一个pip图形化（GUI界面）辅助管理工具

首先搜索出电脑上安装的python版本及路径放在列表中，用户点击哪个就列出哪个版本中已安装的包。所有耗时操作添加了操作前的提示信息，并在操作结束后显示明确的结果。

“列出python”按钮，提供计算机中安装所有python版本（含路径）

“安装包”按钮，提供对话框输入包名进行安装

“包卸载”按钮，可卸载选中的Python包

“包升级”按钮，可升级选中的Python包到最新版本

“镜像源”按钮，出现内置清华、阿里云、腾讯云和官方源等多个镜像源，用于选择

“刷新”按钮，用于列表中显示刚刚安装的包

运行效果如下：

这个工具，利用了多个模块/包/库：

sys（提供与 Python 解释器强相关的功能）、os（提供操作系统相关功能）、subprocess（用于运行外部命令或程序）、json（用于处理 JSON 数据）、shutil（提供文件和文件集合的高级操作）、datetime （用于处理日期和时间），这些都

是 Python 的标准库，不需要安装。

PyQt6 是一个功能强大的 GUI 框架，适用于开发复杂的桌面应用程序。通过安装 PyQt6，你可以使用上述导入的模块来构建用户界面。

源码如下：
