【selenium】pip install selenuim失败问题解决

背景

    windows系统安装PyCharm和python(3.12版本)，配置python环境变量。

    PyCharm引入chromedriver，PyCharm使用pip install selenium下载selenium。

报错信息

安装selenium报错信息：

解决过程

    度娘上看了各种类似报错的处理方法，跟着折腾了一遍，花了一整天都没搞定，郁闷了。

    第二天继续处理，看到上文python版本标红，敏感的小伙伴可能发现为什么要标红了。因为这特么就是我忙碌了一整天一无所获，搞不定selenium安装的罪魁祸首！！！

    再搜到一篇文章提到了python版本的问题，另想起以前一起写代码的小伙伴们都说过，python版本过高可能会有问题的。果断不再从报错信息入手，换个思路，直接给python版本降级。。卸载掉3.12版本的python，重新安装3.9版本的。

    python官方下载是真的慢，用国内镜像，python下载地址：CNPM Binaries Mirror

    pycharm里继续pip install selenum，重启pycharm，搞定了！！！！

    selenium这不就有了么~~~~
