"Modules installed", but nothing shows up

Question

I decided to restructure this post, since I learned new stuff:

I wrote a script, which I want to use as an addon. I wrote the necessary code for that and it works like a charm...

...until I want to install the .py

Installing works fine, since I can check for it in the scrips\addons dir. It just doesnt show up in the addons menu, where I need to tick the box to activate it.

I tried:

• removing dots and spaces from the .py name

• deleting and reinstalling it multiple times

• moving it in the dir manually

• changing the .py name to all sorts of stuff

• changing the "Version" in bl_info to all sorts of stuff

Code, containing the error:

#################################################
# Ive cut all the stuff you guys dont care about.
# The error must be in the remaining code
# since this still does not install

Old Post:

I wrote an Script, which works fine (thanks to you all btw :D)

Now, I want to use it as an Addon. I have seemingly everything set up.

I have my bl_info and the register and unregister funcs. When I want to install the .py, it looks like its working. When I check my installed addons, however, it does not show up. Same is for the button I want to appear in the 3D View.

Opening the Console, I see the following:

    Modules Installed (my addon 1.0) from 'path\\my addon 1.0.py' into 'path\\Blender Foundation\\Blender\\3.1\\scripts\\addons'

Which is indicating, it worked(?)

The baffling thing is, that it DID work some time ago, but idk what I did -.-

Using Windows, if its gonna be important.

Edit: I watched this Video and I think I did everything he did

Another Edit: Following this post:

Troubleshooting when Addons don't show up

I substituted all dots in the file name (and spaces for good measure) with underscores. The post states, I am not allowed to use dots in the file name, which I hope excludes the .py^^?

Answer 1

Your problem was the inclusion of this key/value pair in the bl_info dict.

Whenever I get my bl_info i just copy it out of the Templates > Python > Addon Add Object file and fill it with my own info. Which you can see I did to test your script.

I found an old article in a Blender wiki that seemed to be written around 2.65 with the support key and it worked as well, but it seems like the order is important.

Probably has to do with Python dictionaries switching from arbitrary ordering to strict ordering in Python 3.6
