8.0.3 breaks project with: Unable to require `.d.ts` file

[hakan0xFF]

Hey, today I upgraded the ts-node package to the newest version 8.0.3 and it now throws an exception:

TypeError: Unable to require `.d.ts` file.
This is usually the result of a faulty configuration or import. Make sure there is a `.js`, `.json` or another executable extension and loader (attached before `ts-node`) available alongside `graphql.schema.ts`.

The version 8.0.2 works. I had no time to find the exact cause.

I spent some time after upgrade dependencies to find out who broke my project. I installed previous version of the package and it solved issue.

It seems that this commit broke my project.

[murbanowicz]

The same problem here.

[andyianriley]

same here

@blakeembrey any progress for this ?

[blakeembrey]

Does anyone want to provide a reproduction or test case?

I am running into this issue with ts-node 8.0.3, yarn workspaces and TypeScript project references. I was able to reproduce the issue in this minimal example: https://github.com/mfellner/ts-node-issue-797

8.0.2 does not exhibit the problem. Hope that helps!

I can confirm that this happens to me with yarn workspaces, too. But not every import from another workspace package fails. For example I've got a package with only type declarations and an import of those does not crash.

[nolazybits]

yup, same problem.
Also using yarn workspaces.
Also I have added

 "resolutions": {
 "ts-node": "8.0.2"
 },

to the package.json

so ts-node-dev for instance use the right version (and not the latest broken 8.0.3)

[alcuadrado]

I think it may be related to using --files and having tsconfig.json's "include" field matching .d.ts files.

Still an issue in 8.1.0.

• Try running tsc before running your project.
• Solved that for my project:
  • action-land/action-land@ec0ce27#diff-354f30a63fb0907d4ad57269548329e3R15

[gianmarcotoso]

I solved by adding "preserveSymlinks": true to my tsconfig.json file. This was happening within a lerna project, so YMMV.
