Error installing discord.py

ERROR: Command errored out with exit status 1:
   command: 'D:\Python\python.exe' 'D:\Python\lib\site-packages\pip\_vendor\pep517\_in_process.py' build_wheel 'C:\Users\bencr\AppData\Local\Temp\tmph_gglco5'
       cwd: C:\Users\bencr\AppData\Local\Temp\pip-install-zt2pk2qy\yarl

I've never done this before so I'm not entirely sure what I am supposed to do.

The full error is here, I know it's hard to read but putting it in code format was giving it weird issues:

Failed to build yarl multidict
ERROR: Could not build wheels for yarl, multidict which use PEP 517 and cannot be installed directly

You're using Python 3.9 which came out rather recently. Since Python 3.9 is so new, they do not provide "wheels". Wheels are binary modules that allow you to install compiled code without compiling it yourself.

Your options are either to wait until all the maintainers of the dependencies I use (aiohttp, yarl, multidict, PyNaCl) upload wheels into PyPI or downgrade to 3.8 which has wheels already.

[Harmon758]

This should now be resolved with 7f3737f in the latest development version on the master branch.

[Jaimin1732]

I used 3.8.6 and I am still getting the same error.

[losquevedo]

Hi @Harmon758 I'm still seeing this error on Python 3.9.1. Has this fix been pushed out?

[Harmon758]

No, you can see that there hasn't been a release yet since that commit.
See also #5984.

[losquevedo]

Ah thanks. I'll keep an eye on it there.
