"bundled" version isn't compatible with Intel Macs (arm64 executable)

[DivadNojnarg]

I installed air on 2 different machines, a Mac M2 (a week ago) and an imac intel (today). For the latter, I had to do extra steps to make it start, described below.

The error message I had

air Language Server client: couldn't create connection to server.

Using bundled executable as requested by `air.executableLocation`: /Users/davidgranjon/.positron/extensions/posit.air-vscode-0.2.0-darwin-x64/bundled/bin/air

For the Intel Mac this is what I have:

R version 4.2.2 Patched (2022-10-31 r83219)
Platform: x86_64-apple-darwin17.0 (64-bit)
Running under: macOS Ventura 13.7.2

with Positron:

Positron Version: 2025.01.0 (Universal) build 152
Code - OSS Version: 1.95.0
Commit: 66aa3fb7f98eb8d19155cb7220856154f6ede8b3
Date: 2025-01-06T02:47:02.050Z
Electron: 32.2.1
Chromium: 128.0.6613.186
Node.js: 20.18.0
V8: 12.8.374.38-electron.0
OS: Darwin x64 22.6.0

I installed the cli 0.2.0 and downloaded the Air - R Language Support extension from the market place.

In my settings I need to do this to get it start:

"[r]": {
        "editor.formatOnSave": true
    },
    "air.executableLocation": "environment"

Specifically the "air.executableLocation": "environment" variable.

I also observed the same issue on a more recent Positron build (159).

Fun fact, I also updated the M2 installation with the new air cli and the market place extension released today. I can keep the executable location as bundled. I use the same build release for Positron: https://github.com/posit-dev/positron/releases/tag/2025.01.0-152

My first thought was that the Intel Mac release of air is busted, but the fact that you say it works if you use "environment" is interesting, as that means it isn't busted.

So that instead seems to imply that your "bundled" version isn't compatible with your Intel mac somehow, and our github actions workflows have gone awry, at least that's my next guess.

What does this return for you on your intel mac?

PS thanks for the early testing!

[DivadNojnarg]

When I install the CLI on Mac intel I get:

curl --proto '=https' --tlsv1.2 -LsSf https://github.com/posit-dev/air/releases/download/0.2.0/air-installer.sh | sh

downloading air 0.2.0 x86_64-apple-darwin
installing to /Users/davidgranjon/.local/bin
  air
everything's installed!

$ file /Users/davidgranjon/.local/bin/air
/Users/davidgranjon/.local/bin/air: Mach-O 64-bit executable x86_64

Yes it seems that the bundled version is for arm64:

$file /Users/davidgranjon/.positron/extensions/posit.air-vscode-0.2.0-darwin-x64/bundled/bin/air
/Users/davidgranjon/.positron/extensions/posit.air-vscode-0.2.0-darwin-x64/bundled/bin/air: Mach-O 64-bit executable arm64

So the error makes sense.

[DavisVaughan]

Perfect that should give us enough to go off, thanks!

[DavisVaughan]

Ah of course, we run both mac builds on macos-latest (so, with ARM support)

air/.github/workflows/release-vscode.yml

Lines 28 to 33 in dde788f

	- os: macos-latest
	target: x86_64-apple-darwin
	code-target: darwin-x64
	- os: macos-latest
	target: aarch64-apple-darwin
	code-target: darwin-arm64

So of course our installer is going to try and pull the ARM version even when we are attempting to bundle the x86 version

air/.github/workflows/release-vscode.yml

Line 49 in dde788f

- run: curl -LsSf https://github.com/posit-dev/air/releases/latest/download/air-installer.sh | sh

Looks like we could alternatively download and unpack https://github.com/posit-dev/air/releases/latest/download/air-x86_64-apple-darwin.tar.gz ourselves (and if we do it for one OS we may as well do it for all of them for consistency? and not use the installer script directly?)
