Hello folks, I am testing the ESP-IDF environment (1.0.3) within vscode under Ubuntu 18.04LTS.
When running the debug (ESP-prog, ESP32 DOIT target), the ESP-IDF interface throws a syntax error,

Code: Select all

  File "/home/foobert/.vscode/extensions/espressif.esp-idf-extension-1.0.3/esp_debug_adapter/debug_adapter/debug_backend/debug_backend/gdb.py", line 471
    nonlocal target_output
                         ^
SyntaxError: invalid syntax
[Stopped] : ESP-IDF Debug Adapter

This looks like a Python 3 keyword used in a Python 2 environment, and sure enough running a 'ESP-IDF terminal'

Code: Select all

python --version

shows 2.7, while the bash terminal in vscode is 3.6

Code: Select all

.espressif/python_env/idf4.2_py3.6_env/bin/python --version

also gives Python 2.7.17, this is the Python venv location specified in "idf.pythonBinPath", in my installation settings.json

Ubuntu uses Python 2 as default, but I had changed this to Python 3.6, verified in a bash terminal.

My question is whether ESP-IDF vscode extension requires Python 2 (which would require a debug rewrite), or how it is possible to force use of Python to 3 for the ESP-IDF vscode environment.
Are there further steps required to force use of Python 3 using the 'ESP-IDF: Configure ESP-IDF extension' script?
I note that pip fails when 'python3' option is selected for this script install.

It seems that your system environment is using python2 over python3 being added from the extension in idf.customExtraPaths.

What is the content of your environment PATH ? Do you have any reference to python2 before the path of python3 virtual env

You can use the `ESP-IDF: Doctor command` also to check your extension configuration to check if settings are correct.

On the `ESP-IDF: Configure ESP-IDF extension` you can choose which python executable to use as shown in https://github.com/espressif/vscode-esp ... install.md
