Description

npm run build works fine, but upon npm start I get this error:

tsbackend bkrausz$ npm start

> [email protected] start .../tsbackend
> node .nexus/build/api

internal/modules/cjs/loader.js:326
      throw err;
      ^

Error: Cannot find module '.../tsbackend/.nexus/build/node_modules/nexus/dist/index.js'. Please verify that the package.json has a valid "main" entry

.nexus/build/node_modules/nexus only contains (dist/)?components/schema and a package.json (almost like it's incorrectly tree-shaking).

I've tried blowing away .nexus and node_modules.

This works in v0.25.0, just not in next

I have the same kind of problem - .nexus/build/node_modules is almost empty and npm start fails when it can't find the Prisma plugin framework-entrypoint.js. nexus-plugin-prisma directory is there, but depending on the version it only contains the schema-entrypoint or nothing at all. v0.25.0 works but not next.

Any update on this or idea where I could dig? The TS compilation code is a lot to dig through/diffing didn't produce anything obvious, but I'm very excited for the apollo-server switch (batch + file uploads) and would like to switch to next ASAP if I can resolve this.

BTW I tried on -next a few days ago and it was still happening.

Aha...I figured out what it is! Importing from @nexus/schema or nexus/components/schema causes the issue. I was doing import { arg } from "nexus/components/schema"; instead of using schema.arg.

That is...very unintuitive. It'd be great to have a lint rule or similar to prevent the issue.
