Request for Mac users: installing Homebrew

I’m updating the Homebrew installation instructions for the CLI walkthrough

The given ruby command line is now disabled apparently (according to a posting on and has to be replaced. This walkthrough page uses screenshots to illustrate what’s the user should expect to see, so they can’t simply be edited.

I already have brew installed so I can’t be sure what I see when I re-install is what a new user will see.

My request: a Mac user who does not have brew installed, please install it using the bash command

/bin/bash -c "$(curl -fsSL"

and paste the output in a reply post. Screenshots aren’t necessary, the text output is sufficient.

Can’t we just forward to the official brew instructions?

We don’t tell users how to install apt, a browser, tar, whatever… But brew has to be explained? Taking about thrice as much space as the final brew install exercism for the screenshots, for a simple command, that actually is against all proposed best bractices?

We assume people here know a programming language already and to use to ramp up in that language or learn a second, third, xth language, but handhold them for something simple as curl | bash?

@ErikSchierboom Please have a look at Relatively quick fix to update homebrew install by glennj · Pull Request #129 · exercism/interactive-cli-walkthrough · GitHub

I had trouble installing the tooling to actually test it though.

Approved and merged. Waiting for Update homebrew instructions by ErikSchierboom · Pull Request #2241 · exercism/website-copy · GitHub to be approved for the changes to come into effect.
