1、安装ptvsd

pip3 install ptvsd

2、代码头上里添加

import ptvsd

ptvsd.enable_attach(address = ('172.17.0.2',5678))#docker容器的网络地址，开放的端口

ptvsd.wait_for_attach()

3、vscode配置调试环境

{

"name":"Python: remote",

"type": "python",

"request": "attach",

"port": 5678, //开放的端口

"host": "172.17.0.2", //docker容器的网络地址

//这一条很重要，配置远程目录与当前工作目录映射关系，否则无法命中断点

"pathMappings": [

{

"remoteRoot": "/",

"localRoot": "${workspaceFolder}"

}

]

},
