No pybricks on fresh installation

[sivko2]

Hi!

If I launch the app:
robot@ev3dev:~$ python3 vozilo.py
Traceback (most recent call last):
File "vozilo.py", line 2, in
from pybricks import ev3brick as brick
ImportError: No module named 'pybricks'

The test app is quite simple:
robot@ev3dev:~$ more vozilo.py
#!/usr/bin/env pybricks-micropython
from pybricks import ev3brick as brick

print("Hello")
robot@ev3dev:~$

Thank you very much in advance.

Cheers, Roman

I installed PIP and used pip3 to install pybricks.

The python app runs OK but EV3 is not moving at all w/o any errors.

When you run a script like this:

 python3 vozilo.py

It will be run with python3, which is standard Python.

See these instructions to run Pybricks programs.

If you really want to run Pybricks programs from the terminal, you can do:

brickrun -r -- pybricks-micropython /home/robot/vozilo.py

pybricks-micropython is the MicroPython executable, while brickrun is an ev3dev program that takes care of clearing the screen and stopping the motors when the program stops.

Now I get:
ImportError: no module named ‘flask’

MicroPython is not standard Python, so Python packages like flask are not available. You can either use Python 3 or Pybricks MicroPython, but you can't use both at the same time. But you could write two programs, one in Python 3 and one in Pybricks MicroPython that communicate with each other if you need features from both.
