VS Code调试golang。 Delve调试器

I have a problem with the Delve debuger in visual studio code. Debugging begins but nothing happens. There is only information in the console:

time="2018-06-23T16:35:55+02:00" level=info msg="launching process with args: [C:\\Users\\LenovoPC\\go\\src\\test\\debug]" layer=debugger

Configuration of launch.json

"version": "0.2.0",
"configurations": [
    {
        "name": "Launch",
        "type": "go",
        "request": "launch",
        "mode": "debug",
        "remotePath": "",
        "port": 2345,
        "host": "127.0.0.1",
        "program": "${workspaceRoot}",
        "env": {},
        "args": [],
        "showLog": true
    }
]
