这个问题是VS code的坑，不主动更新路径

1. 添加launch.json

2.修改launch.json

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        
        {
            "name": "Python: Current File",
            "type": "python",
            "request": "launch",
            "program": "${file}",
            "console": "integratedTerminal",
            "env": {
                "PYTHONPATH": "${workspaceRoot}"
            },
            "envFile": "${workspaceFolder}/.env"
        }
    ]
}

3. 再跑一次，就好了！！
