Unable to start language server (probably configuration rather than bug)

[njlivesey]

I’m having issues with IDL for VSCode. Things generally appear to be working to a fair degree, but there are error messages on startup which indicate that things are not happy. It says that the IDL Language Server crashed. So far as I can tell I do have node.js installed and in my path. I’m not familiar with Javascript, nor am I that familiar with VSCode, so apologies if the issue is something basic.

I’ve pasted the logs below, as well as a screenshot of the specific message. In case it’s relevant, I’m running VSCode (1.83.1, Universal) on my Mac (MacOS 13.6), connecting via ssh to a linux server (I’ve pasted /etc/os-release below too).

Any pointers are welcome.

Yours,

Hey There!

Reading through the logs, it looks like it is trying to use an older version of node.js (you have version 6 on your system path).

Let me see if I can add in a filter to check the version and ignore node.js if the version is too low which will cause problems.

As a workaround, if you can remove node.js from your path, then that should hopefully work around the problem until we can get a check/fix in.

Hi Zac, Many thanks for following up. Ah, that’s interesting. It seems to be the version supplied by my Anaconda environment. Perhaps I’ll try updating that (though that can give its own problems as perhaps something else requires a version that old).

Alright, I just published a new version of the extension that should ignore any node.js versions less than v16.

If this doesn't fix the problem, let me know and I can poke at it some more!

[znorman-harris]

Just checking in, did the extension update fix the problem for you?

Hi Zach, Thanks so much for following up and sorry for not getting back to you myself. Yes, I believe it did.
