Debugging not possible anymore

Environment data

• VS Code version: Version: 1.28.2 Commit: 7f3ce96ff4729c91352ae6def877e59c561f4850 Date: 2018-10-17T00:20:56.183Z Electron: 2.0.9 Chrome: 61.0.3163.100 Node.js: 8.9.3 V8: 6.1.534.41 Architecture: x64
• Extension version (available under the Extensions sidebar): 22.159.625 (installed from file, error also in 22.165.101)
• OS and version: Linux Ubuntu 18.04
• Python version (& distribution if applicable, e.g. Anaconda): 2.7
• Type of virtual environment used (N/A | venv | virtualenv | conda | …): N/A
• Relevant/affected Python packages and their versions: N/A

Actual behavior

Debugging does not start: In terminal, following command is issued:

cd /<mypath> ; 
env "PYTHONPATH=/<somepath>" "PYTHONIOENCODING=UTF-8" "PYTHONUNBUFFERED=1" 
<path_to_script>/experimental/ptvsd_launcher.py --client --host localhost --port 41741 
/<path_to_script>/<myscript>.py

This results in the error output in terminal:

usage:
 <path_to_script>/experimental/ptvsd_launcher.py [-h] [-V] [--nodebug] [--host HOST | --server-host HOST] --port PORT -m MODULE [arg ...]
<path_to_script>/experimental/ptvsd_launcher.py [-h] [-V] [--nodebug] [--host HOST | --server-host HOST] --port PORT FILENAME [arg ...] 
<path_to_script>/experimental/ptvsd_launcher.py [-h] [-V] --host HOST --port PORT --pid
PROCESS_ID<path_to_script>/experimental/ptvsd_launcher.py: 
error: argument --host: expected one argument

After some time there is a timeout from the debugger:

Here is the relevant launch.json part (unchanged default):

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.

    "version": "0.2.0",
    "configurations": [
        {
            "name": "Python: Current File (Integrated Terminal)",
            "type": "python",
            "request": "launch",
            "program": "${file}",
            "console": "integratedTerminal",
        },
     ]
}

Expected behavior

The debugger should start (as it did until yesterday) and connect.

Steps to reproduce:

1. Take default launch.json and try to start any python script with “Python: Current File (Integrated Terminal)”

I’m on a mac. I think this happened because I had a version of ptvsd installed in a local venv. ptvsd is included with the python extension itself. This was fixed for me after the latest upgrade of the python extension where they prefer the built-in version of ptvsd by default.

You canpip install --upgrade ptvsd
