Hi,Guys
I met a problem when I study the Nordic DFU following the nordic DFU guideline, but chocked by generating the ZIP pakage.When I use the nrfutil commond, it couldn't generate ZIP
nrfutil pkg generate --hw-version 52 --application-version 1 --application nrf52832_xxaa.hex --sd-req 0x98 --key-file private.key app_dfu_package.zip
The reported error:
$ nrfutil pkg generate --hw-version 52 --application-version 1 --application app.hex --sd-req 0xAE --key-file private.key app_dfu_package.zip
Traceback (most recent call last):

I put the privait.key, app.hex bootloader.hex,softdevice.hex in the same location. It seems that there is something wrong with the Python, but I don't know what is, Iinstalled python3.7.4.
Can anyone help me? Thanks.
