after lefthook install, every hooked git actions results in /usr/bin/env: ‘node’: No such file or directory

Steps to reproduce

curl -fsSL https://bun.sh/install | bash
cd <repo>
bun add -D lefthook
<define any lefthook action, eg. commitlint>

Hey! Thank you for creating an issue. Do you have an idea of how an executable script could be run with either nodejs or bun? I can think of a statically built executable (probably with bun) but I have concerns. It would be great to know if there's a common solution for such cases. I will investigate

[cethien]

bun is intended as a node replacement, so just calling a script.js file should work fine.

i will check out some stuff and give a comment

@mrexox @cethien #705 maybe fixes this case as removes require of Node.js and #!/usr/bin/env node

[Blaquewithaq]

For those of you, that want to utilize this package with bun now, Ive figured out a quick patch solution until bun support has been officially added.

Add these to your package.json file and you'll be good to go.

"prepare:lefthook": "lefthook install && bun -e \"const fs=require('node:fs'); fs.writeFileSync('node_modules/lefthook/bin/index.js', fs.readFileSync('node_modules/lefthook/bin/index.js', 'utf8').replace(/^#!\\/usr\\/bin\\/env\\s+node/gm, '#!/usr/bin/env bun'))\"",
"postinstall": "bun prepare:lefthook"

@Blaquewithaq, thanks for the temporary fix!

Any news on if @dalisoft's PR removes the node dependency to allow runtime independence? Using the above solution is a whole lot of verbose that would be amazing to clear up.

Like @cethien said, Bun is a node runtime replacement, we could simply run any script.js using either Node or Bun depending on the first that passes, since the result will be runtime independent once converted to git hooks.

[cethien]

since I opened the issue, I was experimenting around a bit and noticed something:

when installing other tools like esbuild, there is no js script that executes the binary, only a script to install for the right OS.
the root cause for my problem seems to be the js script that runs the binary - is it possible to ditch the index.js alltogether?

[mrexox]

I hope so, I have @dalisoft's PR on my radar, I just need to test it to make sure it solves the issue with bun.

Hey @mrexox, it seems you have merged the PR you referred to here, do you have any updates on this issue? Can it be closed, or are there any extra steps that need to be taken?

[mrexox]

Hey! Unfortunately there was a backward compatibility issue with the PR, I am going to try a slightly different approach and will notify ASAP.

[mrexox]

@cethien could you please check if the newest lefthook version works? I've changed the order of checks in the hook template and it must not fail with /usr/bin/env: ‘node’: No such file or directory

hey, only managed to test now

I removed node from my system, and tested this one:

.lefthook.yml

# yaml-language-server: $schema=https://json.schemastore.org/lefthook.json
# vim: set ts=2 sw=2 tw=0 fo=cnqoj

commit-msg:
  parallel: true
  commands:
    commitlint:
      run: bun commitlint --edit $1

it seemed to work, my commit was some gibberish and i got a commitlint error.

seems to be resolved

Hello again.
Time to time I try to move my Dockerfile from node:alpine to bun:alpine. But it failed with "env: can't execute 'node': No such file or directory".

So I've done
docker run -it oven/bun:alpine sh
$: bun i -g @localazy/cli
The result is the same and I found this bug:

env: can't execute 'node': No such file or directory

What should I do to run the Next app with all deps in Bun:alpine container correctly?

[mrexox]

Right now there is no way to do this other than installing lefthook from a different source (e.g. alpine registry). This is because postinstall hook of the npm package requires node
