No output definition. Probably caused by errors prior to this?

I have to remove node_modules to get the script to run

[abecks]

Just ran into this issue myself, anyone know why its loading stuff out of node_modules even for TypeScript source files with no imports?

[adelsz]

Same issue. Can't run unless I delete the node_modules directory.

I seem to have the same issue on latest version too 0.52.0

[valerioleo]

hopefully this can help somebody. in my case, I was running the code from within a monorepo, where some packages were using mocha. It has been sufficient to use the nohoist feature in yarn workspaces to make it work again 👍🏻

[jwstanly]

@valerioleo how did you configure nohoist to get your monorepo working?

@valerioleo how did you configure nohoist to get your monorepo working?

@jwstanly I did this in my root package.json:

  "workspaces": {
    "packages": [
      ... all packages here
    ],
    "nohoist": [
      "**/mocha",
      "**/jest"
    ]
  },

I'm also having a similar issue when working with a monorepo with yarn workspaces.

I tried playing around with nohoist but couldn't get it to work 😿

This project is like a pure black box that nothing could be controlled properly

[MarcusRiemer]

For the record: Did you check out working with vega/ts-json-schema-generator? It takes a far more sophisticated approach by walking the AST itself (in contrast to this project which effectively just asks the compiler for the type at point). It therefore sometimes lags behind with very recent additions to the type system, but for me it works far more reliable.

This package solved all my problems, thanks!
