## Python
|
||
|
|
|
||
|
|
**Windows**: Go to [https://www.python.org/downloads/](https://www.python.org/downloads/) and run the Python *3* installer
|
||
|
|
|
||
|
|
- in the installer check the "add Python 3.x to PATH" box
|
||
|
|
- also run the "Disable path length limit" action at the end, if you are on Windows 10 and the option is displayed to you
|
||
|
|
|
||
|
|
**Linux**: Install `pip` using the package manager; this will also install Python.
|
||
|
|
|
||
|
|
``` console
|
||
|
|
$ # If you're using Arch Linux
|
||
|
|
$ sudo pacman -S python-pip
|
||
|
|
|
||
|
|
$ # If you're using Ubuntu
|
||
|
|
$ sudo apt-get install python3-pip
|
||
|
|
```
|
||
|
|
|
||
|
|
**macOS**:
|
||
|
|
Ensure that you have python 3 and pip installed. Refer to the following link for [Instructions on how to install python 3 and pip](https://docs.python-guide.org/starting/install3/osx/)
|
||
|
|
|
||
|
|
```console
|
||
|
|
$ python --version
|
||
|
|
Python 3.7.7
|
||
|
|
$ pip --version
|
||
|
|
pip 20.0.2 from /usr/local/lib/python3.7/site-packages/pip (python 3.7)
|
||
|
|
```
|
||
|

## nrf tools
|
||
|
|
|
||
|
|
### nrfutil
|
||
|
|
|
||
|
|
**All**: Open a terminal and install [nrfutil](https://github.com/NordicSemiconductor/pc-nrfutil) as follows. *If you are familiar with python, it is advised to do this in a [virtual environment](https://docs.python.org/3/library/venv.html).*
|
||
|
|
|
||
|
|
``` console
|
||
|
|
$ pip install nrfutil
|
||
|
|
(..)
|
||
|
|
|
||
|
|
$ nrfutil version
|
||
|
|
nrfutil version 6.1.0
|
||
|
|
```
|
||
|
|
|
||
|
|
**NOTE** as of version 6.1.0 nrfutil indicates that it does "not" support Python 3.9 in its pip manifest. Due to this, the above `pip install` command will fail if you have a Python 3.9 interpreter installed. Here's how to work around the issue:

*start of nrfutil python 3.9 workaround*
|
||
|
|
|
||
|
|
``` console
|
||
|
|
$ # these steps can also be done via a graphical interface
|
||
|
|
|
||
|
|
$ # fetch the source code of version 6.1.0
|
||
|
|
$ # or instead of curl you can enter the URL into your web browser
|
||
|
|
$ curl -LO https://github.com/NordicSemiconductor/pc-nrfutil/archive/v6.1.zip
|
||
|
|
|
||
|
|
$ # unzip the code
|
||
|
|
$ unzip v6.1.zip
|
||
|
|
|
||
|
|
$ # go into the new folder
|
||
|
|
$ cd pc-nrfutil-6.1
|
||
|
|
```
|
||
|
|
|
||
|
|
Apply the following 2 patches (can also be done manually by editing these 2 files: `requirements.txt` and `setup.py`)
