python中OpenSSL、urllib3、six以及requests库冲突

最开始原因是因为OpenSSL版本不支持，由于关联的解释器版本问题，链接了OpenSSL版本问题

Traceback (most recent call last): File "D:\Project\PythonProject\pythonProject\PaChong\MyTestRequests\花语.py", line 1, 
in <module> import requests File "C:\Project\Python3.7\lib\site-packages\requests\__init__.py", line 43, 
in <module> import urllib3 File "C:\Project\Python3.7\lib\site-packages\urllib3\__init__.py", line 43, 
in <module> "urllib3 v2 only supports OpenSSL 1.1.1+, currently " 
ImportError: urllib3 v2 only supports OpenSSL 1.1.1+,
currently the 'ssl' module is compiled with 'OpenSSL 1.1.0h 27 Mar 2018'. See: https://github.com/urllib3/urllib3/issues/2168

然后我去OpenSSL官网下载了压缩包进行了解压和配置环境变量发现还是不行，重新卸载安装urllib3、six以及requests库还是不行，只能从新建虚拟环境下手。

PS C:\Project\Python3.12> openssl version
OpenSSL 3.2.1 30 Jan 2024 (Library: OpenSSL 3.2.1 30 Jan 2024)

以下是我的个人解决经历：

---

先新建一个虚拟环境

python -m venv pachong # 创建新的虚拟环境

然后进入虚拟环境目录，激活虚拟环境

.\pachong\Scripts\activate # 激活虚拟环境 
pip install requests urllib3==1.26.7 # 安装requests 和指定urlib3版本

验证重新安装后，清除缓存

pip cache purge

再次检查库版本

pip list

重新更新urllib3库版本

pip install --upgrade urllib3

再重新启动代码，以下是详细过程：

经过此错误，决定还是使用命令行模式运行python项目，不然会有各种各样的问题，这次有可能是因为pycharm的urllib3链接的Openssl关联的Six库起冲突，应该是python版本决定的，针对于python3.10及以上的解释器有关系，其中我只动了urllib3、six和requests的版本，反正各种依赖库总是出问题，推荐老版本的python解释器，新版本确实有点不太好用了
