v9.4.0 cannot resolve .d.ts files

[falsandtru]

ts-loader was able to resolve index.d.ts from index.ts until v9.3.1, but cannot do it since v9.4.0. The errors occurs on Ubuntu 20.04 but doesn't on Windows 10.

Expected Behaviour

no error

Actual Behaviour

Ran into exactly the same issue today. ts-loader@9.4.0 was resolving a local file instead of a d.ts file from node_modules/@types, reporting a false positive circular type definition.

This was likely caused by #1503

@manuth would you be able to take a look please? If we can resolve this quickly that'd be great - if we can't then we'll likely have to revert 9.4.0 for now.

For others bumping on this, please pin to 9.3.1 for now. We'll look to either revert or fix in the near future. @falsandtru thanks for the repro.

We could go forward and disable enhanced-resolver as it used to be.

I will try to work it out using your repository, @falsandtru.

@falsandtru Sadly I could not find myself able to reproduce the issue. For me, the command webpack --env mode=test is working properly using your most recent commit 418756d009a14b300f00a7f75831030ff0a6496a.

Could you please tell me how to reproduce the issue? Is there any other repository or code example causing this error?

[manuth]

@xemlock could you please tell me on which repository and what branch you're facing this issue?

[falsandtru]

@manuth I already fixed the issue on master branch. Please use the commit written in #1504 (comment).

Or revert the change falsandtru/pjax-api@23f3db5
