this still isn't fixed 2 months later and I manually had to make this change

Thanks for letting us know! I was not aware that v3.4 of pyserial was incompatible with the latest nrfutil version. I will report this internally.

Apologies if this has already been addressed elsewhere; I experienced the same problem, and the root cause was pyserial needed to be updated to v3.5 (from v3.4, which is what I had). To solve this, https://github.com/NordicSemiconductor/pc-nrfutil/blob/master/requirements.txt might need to specify >= 3.5 for pyserial.

This is very helpful. Thank you.

In my case, I had macOS BigSur with Python Org 3.8.2, which was offering only pc-ble-driver < 0.14 (same issue). Updating to Python Org to version 3.8.6 solved this issue and I managed to install nrfutil 6.1.0 (current version).

When I ran it, I got the "symbol not found" error described in https://devzone.nordicsemi.com/f/nordic-q-a/67790/pc-ble-driver-py-on-mac-importerror-image-not-found .

What solved this second issue was installing nrfutil to the "user" packages (--user), not to the system packages.

Finally, although working, I detected a different behavior: The start of the firmware update process takes much longer than in other platforms or in Catalina. However, it finishes successfully.

I suggest a double-check

No problem. Let me know if there's anything else I can do to help troubleshoot this.

I assume it's just an issue on my end and I will troubleshoot. Thank you for your help. I appreciate it.

Maybe you could try download and install the pc_ble_driver_py-0.15.0-cp38-cp38-macosx_10_9_x86_64.whl package manually (https://pypi.org/project/pc-ble-driver-py/#files)?

I'm sorry. I forgot to mention that I'm using pyenv. I can definitely see that Python 3 is being used. I ran the command you gave but modified for my pyenv install. Same issue:

RE: nrfutil on OSX Big Sur fails to execute: symbol not found

Vidar Berg — Fri, 20 Nov 2020 18:32:47 GMT

It looks like maybe Python 2.x is used because pip is listing all the old versions of the pc_ble_driver_py package that didn't have Python 3 support (pc_ble_driver_py>=0.14.2 requires python3).

To ensure it's installed with the correct python version, please try to install it like this:

$ /usr/local/bin/python3 -m pip install --user nrfutil

Thank you for the prompt reply. I'm seeing the following:

ERROR: Could not find a version that satisfies the requirement pc_ble_driver_py>=0.14.2 (from nrfutil) (from versions: 0.1.0, 0.2.0, 0.3.0, 0.4.0, 0.5.0, 0.6.0, 0.6.1, 0.6.2, 0.8.0, 0.8.1, 0.9.0, 0.9.1, 0.10.0, 0.11.0, 0.11.1, 0.11.2, 0.11.3, 0.11.4)
ERROR: No matching distribution found for pc_ble_driver_py>=0.14.2 (from nrfutil)

I've updated pip and tried multiple times, according to some other questions I've seen answered, but it's still not working. Any ideas?

Hello,

There have been some reports of compatibility issues with Python v3.9 and nrfutil that we have not been able to resolve yet (e..g this post: https://devzone.nordicsemi.com/f/nordic-q-a/67790/pc-ble-driver-py-on-mac-importerror-image-not-found ) Could you please try with v.3.8.6 from python.org and see if you get the same result? And sorry for the inconvenience.
