💻 Code

// We can quickly address your report if:
//  - The code sample is short. Nearly all TypeScript bugs can be demonstrated in 20-30 lines of code!
//  - It doesn't use external libraries. These are often issues with the type definitions rather than TypeScript bugs.
//  - The incorrectness of the behavior is readily apparent from reading the sample.
// Reports are slower to investigate if:
//  - We have to pare too much extraneous code.
//  - We have to clone a large repo and validate that the problem isn't elsewhere.
//  - The sample is confusing or doesn't clearly demonstrate what's wrong.

import plugin from 'unplugin-detect-duplicated-deps/Vite';

console.log(plugin);

🙁 Actual behavior

https://github.com/tjx666/ts-filename-case-issue/actions/runs/5203586299/jobs/9386641836

macos, windows can pass tsc check, but linux can't, linux output

> tsc --noEmit

Error: index.ts(1,20): error TS230[7](https://github.com/tjx666/ts-filename-case-issue/actions/runs/5203586299/jobs/9386641836#step:6:8): Cannot find module 'unplugin-detect-duplicated-deps/Vite' or its corresponding type declarations.
 ELIFECYCLE  Test failed. See above for more details.
Error: Process completed with exit code 1.

🙂 Expected behavior

Because I set "forceConsistentCasingInFileNames": true options, tsc should throw error on all system, not only linux

[fatcerberus]

forceConsistentCasingInFileNames only ensures the filenames are consistent within your codebase, not necessarily with the file system.

edit: At least that's what I've heard from maintainers. The documentation however contradicts this:

When this option is set, TypeScript will issue an error if a program tries to include a file by a casing different from the casing on disk.

Hmm.

1. maybe this is feature request, implements this can help identify problems in advance
2. we can improve the error report, for example notify user maybe your module path case not right and provide the correct path

I use macos devlop the ts code, code can pass tsc on mac machine, but can't pass the linux ci. This question took me an entire afternoon to investigate.
