在lauch.json中繁成，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}",
# 主要是"env"
"env": {"PYTHONPATH":"${workspaceRoot}"},
"envFile": "${workspaceRoot}/.env",
"debugOptions": [
"WaitOnAbnormalExit",
"WaitOnNormalExit",
"RedirectOutput"
]
},
