Modules not found when bower is not used as package manager about purescript-language-server HOT 5 CLOSED

You're right that you don't want to use both psc-package and bower, so you can just ignore the bower.json, nothing wrong should happen due to it existing. If you install both with bower and psc-package, I could believe odd things happen.

The setting you want in vscode is "Add Psc Package Sources":

The "Package Path" setting also can work as you describe, but this is really only required for more custom scenarios, the "Add Psc Package Sources" will not require updating if you change package set version, for example.

Hi, @nwolverson
I'm using coc.nvim and spago. I have this issue too.
I tried use --config to set addSpagoSources to true like this :

I also tried to set packagePath to .spage, buildCommand to spago build

But this problem always there.

Could you help on this please?

You don't post any detailed error, and no idea what editor or tool you are using with the language server, so hard to help, but "modules not found" sounds like nothing will be working for you - completion, tooltips, etc. The package path there is then irrelevant, what matters is just that you have compiled the project prior to launching the language server (ie your IDE) and paths etc are set up correctly (purs at the right version in your path), and the language server is launched with the right source folders (open your project folder with the bower.json or psc-package.json at the root level).

The setting you see for package paths is only required for a couple of things though - getting documentation when showing completions etc, and navigating to source. If psc-package is used, a setting is available addPscPackageSources which will add the correct psc-package source directories, similarly addSpagoSources for spago - if you're using vscode, for example, this will appear with some similar setting in the config UI.

I've provided a link to the repository to be able to replicate the issue but it is true that I did not specify the IDE I'm using. It's vscode. Sorry for that.

The projects have both a bower.json and a psc-package.json (I don't know if this is a good idea, coming from js feels it's like having a package-lock and a yarn-lock)

When installing the dependencies using psc-package install all deps gets intalled in the .psc-package folfer.

If I also run bower install (which makes no sense because I have everything already installed by psc) the language server works as expected.

I noticed in the Purescript configuration that there is a Package Path pointing to bower_components.

If I point it to .psc-package/psc-0.13.3 I can remove the bower_components folder and everything works.

Is that correct? When using psc instead of bower the Package Path should be updated? Thanks in advance.

Works like a charm now, thanks a lot @nwolverson for the explanation!
