Could not install `event` library


#1

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:

mBlock 5 vs Python editor for mBot 2
#2

Check this old post out:


#3

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')).


#4

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.


#5

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


#6

i have the same problem here: Looking in indexes: https://mirrors.aliyun.com/pypi/simple/:\Public\Programs\mblock\resources\ml\v2\exec\python-env\win\python.exea

#7

it’s python 2 code


#8

and not python 3


#9

This may be an mBlock issue, not one you can fix. :confused:
@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…
