即使我使用 pip3.6 或 pip3，我也会遇到类似的错误

这是我尝试安装 selenium 模块时遇到的错误我尝试卸载并重新安装 python 也添加到路径文件夹，但仍然出现这些错误我目前使用的是 Windows 10(最新更新)，所以我认为这不应该是一个问题，请帮助修复

提前感谢您的帮助

ReadTimeoutErrors 主要是由于网络问题而发生的。如果互联网连接中断或速度太慢，则可能会发生这种情况。一种可能的解决方案是在 pip install 命令中传递增加的 default-timeout 标志，如下所示:

pip install selenium --default-timeout=100

如果 100 不行，也可以尝试使用 200。
