Question: trying to download discord.py using pip install, gave me the error message in the title. I installed using cmd and the commands py -m pip install -U discord, the cmd was also run in admin. tried using pip, pip3, and pip3.9, all of which didnt work. I tried uninstalling/reinstalling/upgrading (in that order) the said libraries:  pip yarl multidict wheel setuptools  versions of python that I tried (in all versions are downloaded with default settings with nothing changed): python-3.9.0-amd64.exe python-3.9.0.exe I tried researching about wheels and tried installing with --no-binary :all: as well, but it gave the same error message below. in all the iterations of what I have tried, it churned out the exact same error message without any deviation ples help :<  Using cached discord-1.0.1-py3-none-any.whl (1.1 kB) Collecting discord.py>=1.0.1 Using cached discord.py-1.5.1-py3-none-any.whl (701 kB) Processing c:\users\mt\appdata\local\pip\cache\wheels\b6\9c\bd\6b99bc6ec9dab11f3756d31fb8506d3ecf07aea58b6201f539\aiohttp-3.6.3-py3-none-any.whl Collecting attrs>=17.3.0 Using cached attrs-20.2.0-py2.py3-none-any.whl (48 kB) Collecting chardet<4.0,>=2.0 Using cached chardet-3.0.4-py2.py3-none-any.whl (133 kB) Collecting async-timeout<4.0,>=3.0 Using cached async_timeout-3.0.1-py3-none-any.whl (8.2 kB) Collecting yarl<1.6.0,>=1.0 Using cached yarl-1.5.1.tar.gz (173 kB) Installing build dependencies ... done Getting requirements to build wheel ... done Preparing wheel metadata ... done Collecting multidict<5.0,>=4.5 Using cached multidict-4.7.6.tar.gz (50 kB) Installing build dependencies ... done Getting requirements to build wheel ... done Preparing wheel metadata ... done Collecting idna>=2.0 Using cached idna-2.10-py2.py3-none-any.whl (58 kB) Building wheels for collected packages: yarl, multidict Building wheel for yarl (PEP 517) ... error ERROR: Command errored out with exit status 1: command: 'c:\users\mt\appdata\local\programs\python\python39\python.exe' 'c:\users\mt\appdata\local\programs\python\python39\lib\site-packages\pip\_vendor\pep517\_in_process.py' build_wheel 'C:\Users\MT\AppData\Local\Temp\tmptlhkh7zi' cwd: C:\Users\MT\AppData\Local\Temp\pip-install-nztu4nu2\yarl Complete output (35 lines): ********************** * Accellerated build * ********************** running bdist_wheel running build running build_py creating build creating build\lib.win-amd64-3.9 creating build\lib.win-amd64-3.9\yarl copying yarl\_quoting.py -> build\lib.win-amd64-3.9\yarl copying yarl\_quoting_py.py -> build\lib.win-amd64-3.9\yarl copying yarl\_url.py -> build\lib.win-amd64-3.9\yarl copying yarl\__init__.py -> build\lib.win-amd64-3.9\yarl running egg_info writing yarl.egg-info\PKG-INFO writing dependency_links to yarl.egg-info\dependency_links.txt writing requirements to yarl.egg-info\requires.txt writing top-level names to yarl.egg-info\top_level.txt reading manifest file 'yarl.egg-info\SOURCES.txt' reading manifest template 'MANIFEST.in' warning: no previously-included files matching '*.pyc' found anywhere in distribution warning: no previously-included files matching '*.cache' found anywhere in distribution warning: no previously-included files found matching 'yarl\*.html' warning: no previously-included files found matching 'yarl\*.so' warning: no previously-included files found matching 'yarl\*.pyd' no previously-included directories found matching 'docs\_build' writing manifest file 'yarl.egg-info\SOURCES.txt' copying yarl\__init__.pyi -> build\lib.win-amd64-3.9\yarl copying yarl\_quoting_c.c -> build\lib.win-amd64-3.9\yarl copying yarl\_quoting_c.pyi -> build\lib.win-amd64-3.9\yarl copying yarl\_quoting_c.pyx -> build\lib.win-amd64-3.9\yarl copying yarl\py.typed -> build\lib.win-amd64-3.9\yarl running build_ext building 'yarl._quoting_c' extension error: Microsoft Visual C++ 14.0 or greater is required.

Answer: I also had the exact same issue today, since i downloaded node.js and it updated my python 8 to python 9 and i had to reinstall all of my moduels including dpy. The solution is to follow what it says error: Microsoft Visual C++ 14.0 or greater is required.
