west installation problem

[Bergmann]

Hi, I followed the Getting Started Guide from the nRF Connect, but when I got to part 2 "Clone the nRF Connect SDK" I get stuck:
The error message: 

bash: west: command not found

[benjaminb@benjamin-pc ~]$ pip3 install --user west

[benjaminb@benjamin-pc ncs]$ west init -m github.com/.../fw-nrfconnect-nrf
bash: west: Kommando nicht gefunden.

What did I do wrong or how can I make the west command work?

I use Manjaro Linux by the way.

Thanks to all answers

Hi, looks like it got installed correctly so maybe the path to your python packages have not been added to your PATH variable?  I think the executable will be installed to ~/.local/bin on most if not all linux distros. So you can try add this to your path: export PATH=%PATH:${HOME}/.local/bin

[Bergmann]

Thanks, that worked fine.

export PATH=%PATH:~/.local/bin  worked. Didn't know that command, so thanks.

Minor edit, instead of % use $ otherwise you the current PATH value will be overwritten without retaining the paths already in PATH:

PATH=$PATH:${HOME}/.local/bin

This step is missing in west installation step between install and running west.
