invalid syntax

[Luca Danieli]

Hello, there. I just installed the v3.3.0, but I am not sure it is the last version.

Anyway I get an error while calling the library:

    from pubsub import pub

  File "/home/luca/.local/lib/python2.7/site-packages/pubsub/pub.py", line 146

    def getDefaultPublisher() -> Publisher:

                              ^

SyntaxError: invalid syntax

Can you help me?

For sure. Is there a reason that you are not using latest (which is just over a year old)? V3.3 is already 4 years old.

BTW if you just do "pip install pypubsub" you get the latest, v4.0 (might have to do "pip3 install pypubsub" if you are on linux, depending on your setup).

No reason. Just searched on Google. I will try now, thanks meanwhile!

Ok, just installed it correctly:

Collecting typing (from pypubsub)

Installing collected packages: typing, pypubsub

Successfully installed pypubsub-4.0.0 typing-3.6.4

but unfortunately I get the same error. Should I do something to update what pubsub to use? Or has it changed automatically?
