Installation in devcontainer fails on Apple Silicon

[unikitty37]

I cannot install the gem in a VSCode devcontainer running on an Apple M1 machine; it complains that some vital component is missing.

The README says I need a C99 compiler and GNU make, but there's not really much of a clue on how to set this up in devcontainers. Adding the llvm and make features doesn't help (and Ruby is already installed and working).

Would it be possible for the README to list the features that need to be installed for devcontainer users? (Even better: would it be possible to have pre-compiled binaries available for Apple Silicon, thus saving a lot of time when rebuilding the container? :)

devcontainer.json

{
  "name": "Ruby on Rails & Postgres",
  "dockerComposeFile": "docker-compose.yml",
  "service": "app",
  "workspaceFolder": "/workspaces/${localWorkspaceFolderBasename}",

  "features": {
    "ghcr.io/itsmechlark/features/redis-server:1": {},
    "ghcr.io/jungaretti/features/make:1": {},
    "ghcr.io/devcontainers-community/features/llvm:3": {}
  },

  "forwardPorts": [],

  "postCreateCommand": "bundle install && rake db:setup",

  "remoteUser": "vscode"
}

Hey @unikitty37 — I think this might be an issue where prism it being installed twice at the same time. It's being installed once with bundle and then another time while ruby-lsp is installing it. This is creating a conflict in the gem installation directory. We'll look into some solutions here.

I opened an issue for this upstream in rubygems (https://github.com/rubygems/rubygems/issues/7786). In the meantime I'll see if there's a way we can look at handling this in prism specifically.
