I am following the freeCodeCamp.org tutorial on youtube: https://www.youtube.com/watch?v=M576WGiDBdQ&t=190s and

What can I do to install web3 properly?

[kclowes]

That error isn't one I've seen before. I would try to set up a fresh environment. Instructions to do so can be found here. Please report back if there are new errors you can't resolve after installing in a fresh environment, or close the issue if you get it figured out. Thanks!

[fselmo]

This issue is being tracked by ethereum/eth-account#132. I am going to close this in hopes of keeping the conversation in one place.

For now, the most relevant documentation can be found here: https://web3py.readthedocs.io/en/stable/troubleshooting.html#why-am-i-getting-visual-c-or-cython-not-installed-error

We realize this does not seem to work for everyone and we expect to get to this issue very soon.
