Vendored Ruby install fails with unhelpful message on i686 about brew HOT 6 CLOSED

Hi. Please always fill out the issue template.

We do not support 32 bit platforms for the time being. See https://docs.brew.sh/Linuxbrew.

Linuxbrew does not currently support 32-bit x86 platforms. It would be possible for Linuxbrew to work on 32-bit x86 platforms with some effort. An interested and dedicated person could maintain a fork of Homebrew to develop support for 32-bit x86.

Yes I understand the architecture is not supported. Could you consider a more helpful error message in such cases?

from brew.

I think yes. We could bail out directly in this script in case we hit a 32 bit case: https://raw.githubusercontent.com/Linuxbrew/install/master/install.sh

@sjackman What do you think?

I'm not a ruby person so I don't know if I can install a version that linuxbrew supports and indicate that with an env var. If that's possible, it would be nice to document that on the vendor install failure.

I suspect it must be a pain to support error messages like this for every case, but it'd be a bit help to know why the shell one-liner on the website failed.

Thanks.

I've opened PR Linuxbrew/install#46 to check the CPU type. This PR also addresses the issue that ARMv7 would fail to download the appropriate bottle for ARMv6.

As long as you understand that you're in uncharted territory, I'm happy to point you in the right direction. Install a Ruby version ≥ 2.3.7 (ideally exactly version 2.3.7), add it to your PATH, and then run the installation one liner. Feel free to comment here if you run into any more trouble.
