Trouble Building VSCode Extension

I’m trying to build the VSCode extension for sourcekit-lsp as per its README but I get failures. This is on a fresh install of Ubuntu 18.04, with the Swift 5.2.2 toolchain. Here’s the output of the log after running npm run createDevPackage:

23 error You can get information on how to open an issue for this project with:
23 error     npm bugs sourcekit-lsp
23 error Or if that isn't available, you can get their info via:
23 error     npm owner ls sourcekit-lsp
23 error There is likely additional logging output above.
24 verbose exit [ 1, true ]

Are there any updated guidelines on this?

Hmm, haven't seen that before. I just tried a clean build and I do not see this issue with either Ubuntu 18.04 (using docker) or macOS.

Maybe this is the issue? I have a much newer version:


$ npm -v


$ npm -v

Yep, that was it. I'm not sure why I was on such an old npm version, but updating it from inside npm fixed it! Thanks!
