error TS2688

🕗 Version & Regression Information

I am using version 4.6.3. I didn't check other versions to see when this was introduced. Nightly version 4.7.0-dev.20220406 also has this issue.

• This is the behavior in every version I tried, and I reviewed the FAQ for entries about TS2688

⏯ Playground Link

Repository: https://github.com/samuelstevens/apl-preview.

💻 Code

I have a file typings/AplRenderer/index.d.ts with typings for a global script.
I also have a file src/frontend/index.ts with /// <reference types="AplRenderer" />.
I specify ./typings as a typeRoots in my tsconfig.

🙁 Actual behavior

On macOS, npx tsc typechecks correctly. On Ubuntu 20.04.4 LTS, npx tsc complains error TS2688: Cannot find type definition file for 'aplrenderer'.. I use npm ci to install both from scratch.

🙂 Expected behavior

I expect them to be the same on both OSes.

Looks related to #45096

Great catch. I changed everything (folder name, directive) to all lowercase on the linux machine and it worked.

Not sure if I should close this (because I have a solution) or leave it open (because there was no update to typescript).

Looks like a duplicate IMO. You might also try turning on forceConsistentCasingInFileNames to see if that helps
