Visual Studio Code Python Timeout waiting for debugger connection

Question

I'm running the visual studio code tutorial with Python and am unable to connect to the debugger. Google / SO are coming up empty when I search. Usually I use Anaconda with Jupyter, so I'm connecting Visual Studio Code to the python in my activated 3.6 virtual environment. I tried pip installing ptvsd in my virtual environment, but that did not make a difference in what I am seeing.

I would welcome any suggestions. Screenshots included below. launch.json in the bottom screenshot

Solution 1

Open the launch.json file and add the following configuration:

{
     "name": "Python: Debug Console",
     "type": "python",
     "request": "launch",
     "program": "${file}",
     "console": "internalConsole"
}

When you specify none internalConsole for the console, it will run the debugger in the debugger console instead of running in the internal or external terminal.

Solution 2

I had the same issue, so I added the following line to the settings.json file:

{
    // to fix 'Timeout waiting for debugger connections'
    "python.terminal.activateEnvironment": false
}

Solution 3

I had this same problem today. I think it might be a connection problem when the debugger tries to connect to an integrated PowerShell terminal inside Visual Studio. If I change to using an external terminal to run the program then it works okay, and the debugger connects to the external terminal and I can debug perfectly fine. This is my entry for the external terminal launch in launch.json

{
    "name": "Python: Terminal (external)",
    "type": "python",
    "request": "launch",
    "program": "${file}",
    "console": "externalTerminal"
},

Solution 4

I had the same issue. fixed by use "integratedTerminal".
ps.my system win7

{
            "name": "Debug",
            "type": "python",
            "request": "launch",
            "program": "${workspaceFolder}/main.Py",
            "console": "integratedTerminal"
}

Solution 5

Change your integrated terminal shell to cmd.exe. This will allow the default launch.json to debug with the Current File (Integrated Terminal) option.

• More information about the integrated terminal: https://code.visualstudio.com/docs/editor/integrated-terminal

This change has fixed other bugs in my Visual Studio Code + Python integration, such as the double call to Run Python File in Terminal that was frequently required. It was a nice suggestion coming from an internal dialog in version 1.28.2.
