本人用的系统版本是centos7.6（代码只执行黑底白字部分）
报错信息：

我正在查看我的解决方法，发现有些奇怪。
python2-urllib3，这个软件包显然是我的问题的根源。

- So I proceed removing urllib3 installed with pip2:
-因此，我继续删除通过pip2安装的urllib3：
pip2 uninstall urllib3
接下来验证依赖关系并修复错误：
yum check ( 这部看时间 可以省略，）
Loaded plugins: changelog, fastestmirror, langpacks, merge-conf
python-requests-2.6.0-8.el7_7.noarch has missing requires of python-urllib3 >= ('0', '1.10.2', '1')
Error: check all
重装 python-requests
yum reinstall python-requests
