【Python】记录第一次接 python 项目搭建环境的问题

1. python安装指定版本的包

pip install package==version

2. 查看包版本

pip show <package_name>

3. 运行main函数报 coreapi 错误

AssertionError: coreapi must be installed for schema support.
错误解 pip install coreapi

4. 修改 pip install 目录

有可能会没有，要自己手动建

C://Users//账号//AppData//Romaing//Python//pip//pip.ini

5. 修改 pip 配置源

pip install mysqlclient -i https://pypi.tuna.tsinghua.edu.cn/simple

6. Python was not found

解决“Python was not found； run without arguments to install from the Microsoft Store…”问题
环境变量里面移除C:\AppData\Local\Microsoft\WindowsApps 这个变量

7. Could not build wheels for cx_Oracle

ERROR: Could not build wheels for cx_Oracle, which is required to install py：这个 cx_Oracle 安装失败主要是因为python版本过高，我改回 python 3.10.x
