Node is installed by https://github.com/sublimelsp/lsp_utils. But I don't know the details of that or what goes wrong here. Maybe does it work with the non-Electron variant?

[TerminalFi]

I'll test it, I think I did. FWIW, it installs fine outside of sublime when using npm I

Cannot reproduce on Macbook Air M2. For me copilot works but it took a really really long time (4,5min) to download and install.

LSP-copilot used copilot-node-server which is 11.3 MB unpacked.
while @github/copilot-language-server is unpacked 268 MB. That would explain the long wait for installing.

That node_modules/@github/copilot-language-server/native directory is crazy 224 MB...

Oddly enough I got it to work consistently now. But the steps I took

• Close Sublime Text
• Remove LSP-copilot manually
• Remove LSP-copilot cache
• Clone LSP-copilot
• Switch to branch
• Launch ST

Install completed as expected

Could it be that it failed because it takes too much time to download? And after you do npm i for testing on your machine, it now has cache on your machine.

Nope, I am running into this again when doing a upgrade from 1.270.0 to 1.272.0 and the above steps don't solve it. Again, installs just fine outside of Sublime Text. But LSP install fails immediately

[jfcherng]

so I think we are hitting this sublimehq/sublime_text#6424

[TerminalFi]

Ahh yes, absolutely. That is it.
