AttributeError on multiple submodule

[MayukhSobo]

I am getting AttributeError on multiple imports specially the imports like

• logbook.notifiers
• logbook.more

I went ahead checking your __init__.py file and didn't see any entry for these modules

[vmalloc]

The good practice is to import those if you need them. It is not a guarantee in Python packaging that a package should import all its sub-packages in its toplevel namespace...

[vmalloc]

Just to be clear - that means that in your code you should:

from logbook.notifiers import ...

or

from logbook import notifiers

Sorry for a little delayed response but I can import it after restarting my system. But now I am getting the following error

Traceback (most recent call last):
  File "/Users/mayukhsarkar/Documents/Codes/ACE/venv/lib/python3.6/site-packages/logbook/notifiers.py", line 75, in __init__
    import Growl

During handling of the above exception, another exception occurred:

@MayukhSobo IIRC the notifiers module is intended for cases where you have Growl installed...

[MayukhSobo]

@vmalloc Yes but two things here.

First, installing Logbook should have installed all its dependencies which it didn't
Second, I did pip install Growl but it is not working after that too.

[vmalloc]

Growl is not a dependency of Logbook. It doesn't make sense forcing such an unrelated package by default. The right thing is to use extras, and that we should probably do. Until then the right thing to do is include Growl in your own requirements if you require it. Logbook should work with or without it until it requires a feature provided by it.

Secondly, it's strange that pip install Growl doesn't solve it... Are you able to import the required module manually after installing it?

[MayukhSobo]

No I am not able to do it..Have a look

[vmalloc]

Yup, this seems broken... I don't think it ever worked :-(

If you can provide a PR that fixes it that would be very welcome.

[MayukhSobo]

Okay....I seemed to have figured out the problem..

[vmalloc]

@MayukhSobo what is it? I don't see how that import can work in today's Growl...

[MayukhSobo]

Actually can you point out where did you see the growl package? If it is this link then the problem is that it has to be installed and imported with growl with small g...I did that and now it is giving me a different error, but at least not Module Not found.

PS: Please mention if you have user some other package. This seems to the most updated growl for MacOS but I will have to test it. Please close this issue and open a new one..

[vmalloc]

Yes the problem is the code is attempting to import a name not provided by the specific package known as Growl. This could be a historic mistake or a breakage on behalf of the folks maintaining Growl, as this is very old and not very widely used apparently...

[MayukhSobo]

I was wondering if you can move to a better notification system as the current one using Growl is pretty old and requires a paid Growl service.
