解決方法
在lauch.json中,修改 "env": {}為 "env": {"PYTHONPATH":"${workspaceRoot}"}
完整的代碼如下:
{
"name": "Python", "type": "python", "request": "launch", "stopOnEntry": false, "pythonPath": "${config:python.pythonPath}", "program": "${file}", "cwd": "${workspaceRoot}", "env": {"PYTHONPATH":"${workspaceRoot}"}, "envFile": "${workspaceRoot}/.env", "debugOptions": [ "WaitOnAbnormalExit", "WaitOnNormalExit", "RedirectOutput" ] },
