Getting started with Rust on Mac

The Easy Way^TM to Install Rust (on a Mac)

The easiest way to install Rust on a Mac is to head on over to https://www.rust-lang.org/tools/install and use the shell command there -

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

But...

Sometimes we get the following error -

Unknown SSL protocol error in connection to static.rust-lang.org

Sometimes. I got this on my work machine but not my personal one.

You can read a bit about this issue here - https://www.wormly.com/answers/sid/142/topicid/19

There is a fairly straightforward solution

The Fairly Easy Way^TM to Install Rust (on a Mac)

(See Update below before trying this)

We want to use rustup so let's get that first.

brew install rustup

Next let's setup cargo and rustc,

rustup-init

Finally we can check our installation with - rustc --version

UPDATE

jeikabu on Dev.to has given this tip to try.

The old way of installing rustup - curl sh.rustup.rs -sSf | sh

I haven't tested this but it is worth trying before falling back on brew.

Using brew to run a shell script seems like overkill, can you just use the old command:
curl sh.rustup.rs -sSf | sh

Yes, that is definitely the preferred approach and worked on one of my machines.

The second approach is only for when that doesn't work

[jeikabu]

I mean, it's a known potential issue with macOS and client-side certificates, just don't use TLS. No need for brew.

cool, I'll add that to the article, thanks :D

Erroneous. Brew everything; upgrades are easier. I was looking for these steps though. Thanks.
