Cannot install on macos 11.6 with Python 3.6.8

[oubiwann]

When following the instructions on the README, namely pip3 install slack-to-discord, I get this error from pip:

ERROR: Cannot install slack-to-discord==1.0.0, slack-to-discord==1.0.1, slack-to-discord==1.1.0, slack-to-discord==1.1.1, slack-to-discord==1.1.2, slack-to-discord==1.1.3 and slack-to-discord==1.1.4 because these package versions have conflicting dependencies.

The conflict is caused by:
    slack-to-discord 1.1.4 depends on discord.py<3.0.0 and >=2.0.0
    slack-to-discord 1.1.3 depends on discord.py<3.0.0 and >=2.0.0
    slack-to-discord 1.1.2 depends on discord.py<3.0.0 and >=2.0.0
    slack-to-discord 1.1.1 depends on discord.py<3.0.0 and >=2.0.0
    slack-to-discord 1.1.0 depends on discord.py<3.0.0 and >=2.0.0
    slack-to-discord 1.0.1 depends on discord.py<3.0.0 and >=2.0.0
    slack-to-discord 1.0.0 depends on discord.py<3.0.0 and >=2.0.0

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

I tried this first:

    install_requires = [
        "discord.py==2.3.1",
        "urllib3==1.26.16",
    ],

But got the same error. I then set no version for discord.py, and it worked:

    install_requires = [
        "discord.py",
        "urllib3==1.26.16",
    ],

Though this can't really be considered anything more than a work-around.

It seems that the Python version in the setup.py doesn't actually work?

I tried installing with a non-macos Python (homebrew) at version 3.11 and it worked.

Good catch, discord.py>=2.0.0 requires Python 3.8+ so I've updated the requirements of this package to match
