nrfutil on ubuntu does not work

[cpeng]

trying to get nrfutil working on ubuntu, following this guide:

https://infocenter.nordicsemi.com/index.jsp?topic=%2Fug_nrfutil%2FUG%2Fnrfutil%2Fnrfutil_intro.html

after running "pip install -r requirements.txt"

i got this

Collecting pc_ble_driver_py>=0.14.1 (from -r requirements.txt (line 7))
Could not find a version that satisfies the requirement pc_ble_driver_py>=0.14.1 (from -r requirements.txt (line 7)) (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)
No matching distribution found for pc_ble_driver_py>=0.14.1 (from -r requirements.txt (line 7))

Seems it has trouble finding that pc_ble_driver_py. 

What gives?

Thanks.

Hi,

It seems like it may help to update pip, or did you try that already? https://github.com/NordicSemiconductor/pc-nrfutil/issues/288

Hi thanks for your reply.

I have upgraded pip, then proceed to do the following:

pip install -r requirements.txt

Then I got the same error about can't get pc_ble_driver_py.

Any idea what might prevent pip getting pc_ble_driver_py?

Hi,

Python 3 is required starting from the nrfutil v.6.0.0 release, but it looks like you are using Python 2 here. Try with pip3 instead of pip, or call "pip3 install --user nrfutil" if you want to install it directly from PyPi.

I have the same issue using python 3 (pip3:

$ pip3 install --user nrfutil

I fixed it by first installing nrfutil with python 2.7 (normal pip). Then uninstalling nrfutil (pip uninstall nrfutil) and then reinstalling it with python 3 (pip3 install nrfutil).
