Problem with magic mirror eink

Ok, so I am using a Pi zero 2 w, and a 7.5in e-ink display from waveshare. I hope I connected everything right. ( see images) I installed magic mirror and this project: https://github.com/winstonma/RPi-MagicMirror-Waveshare on the almost last step, where I should install sudo pip install -r requirements.txt I always get an error externally-managed-environment When I try to start the script with pm2 start main.py --name "eink-update", it shows 0 | eink-update | fork | 45 | online | 0% | 2.9mb and also a second line for "node". then I use pm save, but nothing shows on my screen. When I use pm2 list it gives me an errored status 0 | eink-update | fork | 60 | errored| 0% | 0mb according to my other windows, the magic mirror programm itself should have been started, and accassable with localhost:8080, but idk how to troubleshoot if the error may come from there ( I dont think so ) I also attached images of the board and screenshots , as this is my very first time handeling a Pi and I might have donesomething wrong (?) I'd apprechiate any help

* after using --break-system-packages with the pip command, I circumvented the error, and also the errored message in pm2 list. However, I still do not get any image on my screen
