Cross-platform Docker setup fails on M1 mac while setting up elm using using npm install

[basghar]

Quick Summary: We use docker in order to support multi-platform dev environment. On M1 macs, npm install -g elm fails because there is no pre-build binary for linux_arm64. We want to avoid having different docker for different platform.

This is use-case for #2007

> node install.js

-- ERROR -----------------------------------------------------------------------

I am detecting that your computer (linux_arm64) may not be compatible with any
of the official pre-built binaries.

I recommend against using the npm installer for your situation. Check out the
alternative installers at https://github.com/elm/compiler/releases/tag/0.19.1
to see if there is something that will work better for you.

From there I recommend asking for guidance on Slack or Discourse to find someone
who can help with your specific situation.

• Elm: 0.19.1
• Browser: N/A
• Operating System: Docker on M1 Mac using arm64 linux.

Thanks for reporting this! To set expectations:

• Issues are reviewed in batches, so it can take some time to get a response.
• Ask questions in a community forum. You will get an answer quicker that way!
• If you experience something similar, open a new issue. We like duplicates.

Finally, please be patient with the core team. They are trying their best with limited resources.

Just ran into this same issue.

A workaround I found is to specify v0.19.1-4, which has a commit that added support for ARM (for macOS Silicon). It also added support for linux_arm64 as a byproduct of this.

The current release, one patch version higher at v0.19.1-5 includes a commit that continues to support apple_arm64 but inadvertently drops support for linux_arm64 (which is what Docker uses on hosts that are Apple Silicon, i.e. apple_arm64).

As an alternative nix can be used to build docker images. Because nix has support to build Elm on ARM.

Hi! Is it possible to merge this PR? Or to say what is the problem with it? Because I need to use a linux_arm64 version of elm with npm, and without this fix, it is currently impossible to do that.

Hello,

Any news regarding this PR? It's still a blocker for us. Is there any way we can help progressing this a bit faster?

Thanks!
