🕗 Version & Regression Information
This is the behavior in every version I tried, and I haven't found any issues or FAQ entries about this. Tested only on 4.8.2, sorry. Looks like this might be recent regression after all.
⏯ Playground Link / 💻 Code
I can't reproduce this in neither the playground nor the workbench nor even Linux. The problem appears only on macOS. Here's a repro: https://github.com/alecmev/typescript-type-reference-lowercase-repro Just npm i and npx tsc.
🙁 Actual behavior
index.ts:2:26 - error TS1149: File name '/users/foo/repro/node_modules/@types/react/index.d.ts' differs from already included file name '/Users/Foo/repro/node_modules/@types/react/index.d.ts' only in casing.
The file is in the program because:
Type library referenced via 'react' from file '/Users/Foo/repro/node_modules/@babylonjs/inspector/babylon.inspector.module.d.ts'
Imported via "react" from file '/Users/Foo/repro/node_modules/@babylonjs/inspector/babylon.inspector.module.d.ts' with packageId '@types/react/[email protected]'Note /users/foo vs. /Users/Foo.
🙂 Expected behavior
This is valid code and it works on Linux and/or without moduleResolution: Node16. An unnecessary toLowerCase happens somewhere, but I can't really debug this further since I use Linux and had to use my colleague's computer to create the repro. The title of the issue is only a guess, I don't know the root of the issue.
