nRF Connect Toolchain fails

[Denis D.]

I followed your step by step guide available on your site for installing the SDK and Toolchain. My system are Fedora 36 with VS Code IDE, but the system detects the errors that I report attached in this screenshot:

and in the VS Code IDE output window appear those errors:

********** VS Code Output window content ***************

Kindly, how can I solve those issues?

Thanks in advance.

Hello!

For the VS Code output window error:

Are you running this in a virtual environment or something? Looks like this error is related to your PATH in this environment in that case.

For the 'invalid toolchain' error:

What's the output if you enter 'nrfjprog --version' in your terminal?

Best regards,

Einar

[Denis D.]

Hi Einar,

I will update you.

Now I have installed VS Code without virtual environment.

I see only this two message. How can I solve those issue?

Thanks for all.

Denis

[Einarh]

gn is only needed if you're going to develop applications using Matter, otherwise you can ignore this warning.

Do you have any more details on your shell initialization error?

-Einar

[Denis D.]

No, all this errors are referred to VS Code IDE output window that are attached in the first message of this ticket.

All refer to Python errors.

[Einarh]

You're still getting the same Python errors as in the original post?

In that case you should look into this error message:

ModuleNotFoundError: No module named 'encodings'

This seems to be related to your own Python environment and not the nRF Connect SDK.

Have you installed the Python dependencies as described here?

-Einar

[Denis D.]

Yes, I installed the dependencies, this is the report about 'pip3 list':

As I said in my previous reply, your error seems to be caused by your Python environment, and is probably caused by something you set up before you started installing NCS.

See for example this thread for a similar issue: https://stackoverflow.com/questions/38132755/importerror-no-module-named-encodings

If you were working in a virtual environment earlier, this seems likely to be the root of your issue.

I'm getting the exact same errors on a fresh install under Ubuntu 22.04
