Rails 7 and ESbuild

Im trying to deploy a Rails 7 application.

Im facing issue with ESBuild during yarn install step

Oct. 24 05:43:03 PM  error esbuild-darwin-arm64@0.15.12: The platform "linux" is incompatible with this module.
Oct. 24 05:43:03 PM  error esbuild-darwin-arm64@0.15.12: The CPU architecture "x64" is incompatible with this module.
Oct. 24 05:43:03 PM  error Found incompatible module.
Oct. 24 05:43:03 PM  info Visit https://yarnpkg.com/en/docs/cli/install for documentation about this command.
Oct. 24 05:43:03 PM  rake aborted!
Oct. 24 05:43:03 PM  jsbundling-rails: Command build failed, ensure yarn is installed and `yarn build` runs without errors

I use MacOS for development thus esbuild-darwin-arm64 is in the package.json file. I guess render is expecting esbuild-linux-64. How can I fix this issue?

For reference: Error: The package "esbuild-linux-64" could not be found, and is needed by esbuild · Issue #1646 · evanw/esbuild · GitHub

Certainly, to fix differences between platforms for bundler you need to perform

bundle lock --add-platform x86_64-linux

I checked in my own Rails7 app which uses esbuild and there’s nothing platform specific in my package.json but I can see other platforms in my yarn.lock - and I’m also using an M1 Mac here,

Thank you for the reply.

But my issue is with yarn, not bundle. Im not able to find similar command for yarn.

Sharing my package.json

  "name": "app",
  "private": "true",
  "dependencies": {
    "@hotwired/stimulus": "^3.0.1",
    "@hotwired/turbo-rails": "^7.1.3",
    "autoprefixer": "^10.4.7",
    "esbuild": "^0.14.48",
    "esbuild-darwin-arm64": "^0.15.12",
    "postcss": "^8.4.14",
    "tailwindcss": "^3.1.4"
  "scripts": {
    "build": "esbuild app/javascript/*.* --bundle --sourcemap --outdir=app/assets/builds",
    "build:css": "tailwindcss -i ./app/assets/stylesheets/application.tailwind.css -o ./app/assets/builds/application.css --minify"

Ah, re-reading the error based on your snipper of package.json there, I suspect the issue here is that you explicitly have the darwin-arm64 module in your package.json which will indeed work locally but not on us (or any Linux x86 platform).

My own package.json for a Rail7 app I deploy to us is;

  "scripts": { "build:css": "tailwindcss --postcss -i ./app/assets/stylesheets/application.tailwind.css -o ./app/assets/builds/application.css", "build": "esbuild app/javascript/*.* --bundle --sourcemap --outdir=app/assets/builds" }, "dependencies": { "@hotwired/stimulus": "^3.0.1", "@hotwired/turbo-rails": "^7.1.0", "@rails/actioncable": "^7.0.0", "@rails/activestorage": "^7.0.0", "@rails/ujs": "^7.0.0", "debounce": "^1.2.1", "esbuild": "^0.14.2", "postcss-import": "^14.0.2", "postcss-resolve-urls": "^0.0.3", "turbolinks": "^5.2.0" }, "version": "0.1.0

and as I said, I’m using an M1 Macbook pro as well., maybe try removing

 "esbuild-darwin-arm64": "^0.15.12",

Thank you. removing “esbuild-darwin-arm64” helped.
