Could not install `event` library

[rom1v]

In the Python editor containing a simple program:

# generated by mBlock5 for CyberPi
# codes make you happy

import mbot2, time, event, cyberpi

@event.is_press('a')
def is_btn_press():
    mbot2.straight(100)
    cyberpi.led.show('red orange yellow green cyan')

When I click “Run”, it opens a prompt:

event library not found, so the project may not run as expected.

Install event library right now?

I click “Yes”, but installation fails, with the following logs:

Check this old post out:

Mbot neo/2, Mac, Python

Hello, @burghout, this may be a problem with the event library not being supported yet in the python editor. You may have to learn how to code this without the include (library). One issue may be bad code. I would recommend that you use this code: import event import time import cyberpi Instead of this code: import event, time, cyberpi Your problem may also be that you need to install the cyberpi library manually by following these steps: Click the Libraries tab. [Screenshot%20…

[rom1v]

I checked, but this does not help.

Btw, I have the same error message if I try to install event in the PIP tab from that “Libraries” menu.

There is definitely a syntax error in some setup.py file, but I’m a bit lost on Windows: the path seems to be C:\AppData\Local\Temp\pip-install-j0bqq10i\event\setup.py, but C:\AppData does not even exist.

This error prevents me to run a python program when I press CyberPi button (because it requires @event.is_press('a')).

[rom1v]

Oh, with the old mBlock python editor (the “Python” tab on the right), it works!

It’s not intuitive, because it opens an empty text file: Suggestion: Hint for viewing/editing micropython code in UI
But you can get the python code generated from the blocks, copy-paste it there, (edit it) then “upload”, and it works.

This is the only way I managed to run some python code I edited manually on the robot.

I’m glad you have a workaround until a solution can be found!

[Indyr.GG]

it’s python 2 code

[Indyr.GG]

and not python 3

[Best_codes]

This may be an mBlock issue, not one you can fix.
@Indyr.GG try https://python.mblock.cc/ just to make sure it fails there, as well.

I guess the next-best thing to do is contact support via email (support@makeblock.com).
Good luck…
