- VSCode
- WSL2
- Ubuntu 22.04
- Python 3.10.12
I am using the Code created when using Workspace/New Project... Project consistently fails with: ConnectionRefusedError: [Errno 111]
Investigative information
I have tried everything I can find on the internet including #2808; Python works on this VM; I have deleted the project and started again and restarted WSl2
If I run: func host start / func start the function works with: p://localhost:7071/api/http_trigger1?name="test"
If I try to make a C# function works as expected.
I modified launch.json to include: "command": "host start --verbose", Attached is the Output:
- Executing task: .venv/bin/python -m pip install -r requirements.txt
Requirement already satisfied: azure-functions in ./.venv/lib/python3.10/site-packages (from -r requirements.txt (line 5)) (1.18.0)
Terminal will be reused by tasks, press any key to close it.
Executing task: . .venv/bin/activate && func host start --verbose
Found Python version 3.10.12 (python3).
