电脑重装后 python 2 3快速安装

背景：

电脑重装后，python也要跟着重装，将安装包、环境变量备份等安装完成后直接安装

重装前

1. pip包备份,命令窗口

1 pip freeze > py2.txt #python2的包
2 pip3 freeze > py3.txt #python3的包

2.环境变量备份,命令窗口

1 set >> D:\env.txt

重装后

1.安装python2、3

 安装包可以从官网下载，也可以使用网盘中的文件

提取码：f0q3

2.将python3目录下的 python.exe 复制一份，修改成 python3.exe

3.将重装前2中的环境变量中的 python路径加到 环境变量中

C:\Python27;
C:\Python27\Scripts;
C:\Python27\Lib\site-packages;
C:\Python37;
C:\Python37\Scripts;

4.安装VCForPython27 包，不安装的话 第五步会报错 error: Microsoft Visual C++ 9.0 is required

直接下载安装 或从重装后步骤1中的网盘中下载

5.安装包

1 pip install -r py2.txt #安装python2的包
2 pip install -r py3.txt #安装python3的包
