[MrTanoshii]

What happened?

Version: 5.0.9
Operating System: Windows

Steps:

1. Setup venv
2. pip install honeybot

Expected behavior:

Installation completes without error.

Additional information:

I tried the recommendation from https://stackoverflow.com/questions/54338270/syntax-error-after-installing-futures-package-in-my-virtualenv and downgraded my setuptools to 45.2.0 and it worked.

Hi! I think I can take this one.

Is pip install 'futures<3.0.0' required in the build.yml file?

It seems this might be the cause of the problem. From what I've read futures shouldn't be installed with Python 3.

[MrTanoshii]

To be completely honest, I'm not sure where the requirements are being kept for the honeybot core
The only reference to futures I have found so far is in

honeybot/.github/workflows/build.yml

Line 42 in 00a75fc

pip install 'futures<3.0.0'

Yes that is correct, I too understand that futures is now part of the standard library in python3+
I wonder if there is a way to retain backwards compatibility whilst not forcing "hacks" such as the setuptools downgrade mentioned above

[ogabrielluiz]

From what I could see locally and in your log output, the problem lies in that futures is installed by some other dependency and gets the first version that works: 3.0.5.

I ran the GitHub workflow locally too and it works. It probably does so because of the pip install futures<3.0.0 command.

One thing to mention is that in spite of the errors, the installation completes.

[ogabrielluiz]

it is python dependency error, downgrade the version of python to 3.8 or 3.7 and check again

If I understood it correctly, the objective is to be able to install in 3.10 without errors.

I guess so too
