No prebuilt binaries found (target=undefined ...)

[LMolr]

After installing the plugin on a fresh Code installation, I cannot start the language server due to missing prebuilt binaries.

Your environment

• vscode-ruby version: 0.22.3
• Ruby version: 2.6.0p0
• Ruby version manager (if any): rbenv 1.1.2
• VS Code version: 1.35.0
  (Electron 4.1.4 Chrome 69.0.3497.128 Node.js 10.11.0 V8: 6.9.427.30-electron.0)
• Operating System: Arch Linux Linux 5.1.7-arch1-1-ARCH
• Using language server? Yes

Expected behavior

Language server should start.

Actual behavior

In Output Window, the Ruby Language Server context shows the following error message:

[Info  - 12:23:12 PM] Initializing Ruby language server...
[Info  - 12:23:12 PM] Rebuilding tree-sitter for local Electron version
[Error - 12:23:13 PM] Server initialization failed.
  Message: Request initialize failed with message: No prebuilt binaries found (target=undefined runtime=undefined arch=undefined libc=undefined platform=undefined)
  Code: -32603

NOTE: I don't know if the undefined values are an hint about the origin of the problem.

Can you try v0.23.0? I upgraded prebuild-install there and that may have also fixed a bug with detection.

[LMolr]

Hello, I also tried 0.23.0 and all the listed versions from 0.20.0 on, but I always get the same error.
Is there something I can do to get more details?

Thank you

The undefineds are the issue as you suspected. It means prebuilt-install can’t figure out what arch it is running on.

If you open a console does the process global have arch and such defined?

I’m also pretty sure someone else on Arch had issues before too.

[LMolr]

In dev console look defined

process.platform

-> "linux"

process.arch

-> "x64"

process.versions.modules

-> "69"

[LMolr]

I tried to debug the extension but unfortunately the Launch Extension run configuration times out with a popup over the electron window saying "Cannot debug extension (timeout)." :( .

All of the code related to this is here: https://github.com/rubyide/vscode-ruby/blob/master/server/src/util/rebuilder.ts#L22-L42

FWIW, I'm also experiencing this on a Mac, fresh Code Insiders install.

I have the same issue:

[maletor]

Right, so I am ABI 67 and @LMolr is 69. That's the issue since tree-sitter-ruby is living in the dark ages on 64.

[maletor]

I downgraded to nodejs-lts-dubnium on Arch. IDK what @LMolr is doing. That ABI is non-existent.

Either way, Message: Request initialize failed with message: No prebuilt binaries found is still found with

> process.versions.modules
'64'

[wingrunr21]

ABI 64 is Electron 4 and 69 is Electron 4.0.4. 64 isn't exactly ancient :-P

I'll push a PR to tree-sitter-ruby and bump the version here. I am looking at moving over to the WASM version of tree-sitter to avoid this in the future. It wasn't available when I initially did this implementation.

[wingrunr21]

@BrandonShega what ABI is insiders running right now?

[maletor]

@wingrunr21 the issue might go beyond the ABI version, given I downgraded to Node LTS (ABI 64) and still have these issues, don't you think?

How would arch=undefined be output when process.arch is x64?

[wingrunr21]

The ABI is based on electron (since the server runs within the VSCode instance) not the system installed node versions.

I have no idea why all that stuff is coming back undefined. I think that's probably a prebuild-install bug of some kind.

[maletor]

Ah, makes sense. This is the Electron REPL.
