Thanks for the report @znewbiez1001.
What Elixir and Erlang versions are you using? Could you paste the result of calling :erlang.system_info(:system_architecture) in your project?
I also have a Macbook Pro M1 and calling the previous command returns ~c"aarch64-apple-darwin23.5.0", which matches with the aarch64 clause.
@belaustegui oh how could it be? My result is the same as @LostKobrakai said
arm-apple-darwin23.3.0
I’m using
Interesting. Bun supports only Elixir 1.15 and newer versions. In fact it uses Mix.ensure_application!1 which is only available from Elixir 1.15.
Hi all!
I’ve just released bun 1.3.1 which contains more improvements for process wrapping. Now we just wrap bun build. This allows you to use bun run to call other commands (for example bun run tailwind to build your CSS without using the Elixir Tailwind package).
Thanks @Sgoettschkes for reporting this and following up with a detailed investigation.
Check out the GitHub Repo and the Hex.pm package for the release notes and code.
Happy coding! 
Looks like for phoenix builds bun looks exactly like esbuild, are there any notable differences in this regard?
Bun is full JS runtime, not just bundler. That mean that you can also run NPM packages using Bun, which IIRC is not possible with ESbuild. For example I switched from Tailwind to just PostCSS and I can use “regular” package.json with ease without any additional steps.
