[Bug] TypeScript resolution in latest dev build

[AaronDewes]

• I'd be willing to implement a fix

Describe the bug

The latest dev version of TypeScript 4.3 doesn't work anymore, it fails to import anything. This was probably introduced through microsoft/TypeScript#43700.

To Reproduce

Create a project with typescript and any other package. Try to import the package in typescript.

Environment:

• OS: Ubuntu 21.04
• Node version 14
• Yarn version 3.0.0-rc.2

It seems this PR introduced conflicts. Starting from 3.0, when conflicts arise, rather than abort the install, we fallback on the regular TS package (so that you can at least switch to the node-modules linker until we can sort it out). Hence why resolutions don't work.

Note that the failed patch is probably in your install logs (at least the first time you install it).

I don't have them anymore, but I can reinstall if you need them, but if you know what's wrong, you probably don't need it, do you?

Yep I think the info are enough, it was just to provide a bit of context. Thanks for the report 👍

Noticing this on ts 4.3.2. Any updates here?

It seems it's all 4.3.x
4.3.1-rc likewise, patch fails to apply but 4.2.4 is fine
