Hi @Kunal0127 ,

How did you install pubsub module?

[Kunal0127]

i install it separately with "pip/pip3 install pubsub".

Hi @Kunal0127, if you are using Python >= 3.9 I suggest you to use requirements_m1.txt because the requirements are newer than requirements.txt and some requirements are not installing in Python >= 3.9. So just install this way:

pip3 install -r requirements_m1.txt

[Kunal0127]

what I found that Pypubsub & pubsub are deferent module so install it separately can solve this problem.
(and also made a pull request for requirements files. please considers it.)

thankyou

@Kunal0127 we are using Pypubsub not Pubsub. Pypubsub is the name of the project but the module name is pubsub. If you see a Pypubsub example you'll see the package is imported as pubsub.

[Kunal0127]

yes, (but) to run Pypubsub project my system didn't have pubsub module. but now im able to execute project.

thankyou
