VS Code Extension - west flash fails from missing python dependencies

[brendansl]

When trying to flash the hello world program onto an Adafruit nRF52840 Feather through a j link it fails with "FATAL ERROR: one or more Python dependencies were missing; see the getting started guide for details on how to fix". I installed the dependencies using the requirements.txt file in the ncs/v2.3.0/zephyr/script folder, but the problem persists.

OS: Ubuntu 22.04.2

VS Code: 1.78.2

nRF Connect SDK/toolchain: 2.3.0

Hi,

What else to you see in the log? You should be able to see what exactly is missing. That said, there is support for Ubuntu 22.04 in the toolchain manager, and I would recommend using that as that way you get everything set up out of the box (see installing automatically for details).

That's all the terminal output says and generating support information only says "Failure (code 1)" (along with the normal support info). Is there another log that you're referring to? I used the toolchain manager to install automatically.

If you installed via the toolchain manager you should have everything. Have you selected the toolchain from the toolchain manager in VS Code (if it did not happen automatically)? You can do that here:

Also, does building from the command line work? If testing that, remember to open the command line from the toolchain manager (clicking the downwards error to the right of the "Open VS Code" button, and selecting "Open Terminal".

The toolchain is selected.

Opening the terminal from the toolchain manager gives this error:

Fatal Python error: init_fs_encoding: failed to get the Python codec of the filesystem encoding
Python runtime state: core initialized
ModuleNotFoundError: No module named 'encodings'

Building from this terminal seems to work.
