1. 确认安装的Python版本，pip确认安装路径，找到ensurepip模块
PS C:\Users\yangqing> pip.exe -V
pip 24.3.1 from C:\Program Files\Python312\Lib\site-packages\pip (python 3.12)
PS C:\Users\yangqing>
注：这里找 Python 自带模块不是安装模块路径，找到ensurepip自带模块
2. 下载 pip 最新包，并修改ensurepip模块
PS C:\Users\yangqing> cd 'C:\Program Files\Python312\Lib\ensurepip\'
PS C:\Program Files\Python312\Lib\ensurepip> pip.exe download pip -d .\_bundled\
