From @AwayQuEM on June 20, 2017 3:29

Environment data

VS Code version: 1.13.1 on Mac Python Extension version: 0.6.5 on mac Python Version: 3.5.2 OS and version: OS X 10.12.5
ptvsd version:3.0.0 on Mac

Actual behavior

I still got 'Debug adapter process has terminated unexpectedly' with ptvsd==3.0.0

Steps to reproduce:

• run test.py
• then run debug in vscode

Settings

Your launch.json (if dealing with debugger issues):

{
    "version": "0.2.0",
    "configurations": [
         {
            "name": "Attach (Remote Debug)",
            "type": "python",
            "request": "attach",
            "localRoot": "${workspaceRoot}",
            "secret": "secet",
            "port": 8010,
            "host": "localhost",
            "remoteRoot": "${workspaceRoot}"
        }
    ]
}

Your settings.json:

{
    "python.pythonPath": "/Users/away/wanjia/test_remote_debug/venv/bin/python",
    "python.autoComplete.extraPaths": [
        "/Users/away/wanjia/test_remote_debug/venv/lib/python3.5/site-packages"
    ],
    "python.linting.enabled": false
}

Logs

Output from Console window (Help->Developer Tools menu)

address = ('0.0.0.0', 8010)
ptvsd.enable_attach('secret', address)
ptvsd.wait_for_attach()
print('connected')
