Encore's dependency resolver currently requires node_modules. We have looked into supporting pnp but it's not a high priority at the moment. Last time I looked the format is not very well documented so building tooling to support it is relatively difficult.

FYI @arcanis @merceyz

Or are you saying you are using yarn's node_modules mode? That should definitely work.

No, I'm using Plug'n'Play instead of node_modules:

.yarnrc.yml

nodeLinker: pnp

Maybe encore.exe point to C:\Users\<USER>\.encore\runtimes\js\encore.dev\package.json instead of package.json of the project (where I run encore run and where there is encore.app file).

Why encore.dev dependency is duplicated in C:\Users\<USER>\.encore\runtimes\js? encore.dev dependency is already installed in the project (package.json).
