1、问题背景：在本地机安装失败，但在服务器上安装成功；
2、环境对比：两个机器的python版本不一致；
报错如下：

解决方案：
1、进入cx-Oracle · Pyshou 手动去下载whl依赖，发现没有自己的python对于的文件（原因：可能自己安装的版本过高，导致依赖文件没有，所以失败）；
2、重新安装和服务器上一致的python版本(3.7.9)；
3、再次执行：pip3 install cx_Oracle ；
4、【如未遇到则忽略此步骤】报错：WARNING: You are using pip version 20.1.1; however, version 23.2.1 is available.
You should consider upgrading via the 'd:\warfile\python\python.exe -m pip install --upgrade pip' command（解决办法，执行：python -m pip install -U --force-reinstall pip）；
5、再次执行：pip3 install cx_Oracle；文章来源：https://www.toymoban.com/news/detail-701228.html
