TypeScript error in undefined(undefined,undefined)

I am stuck with TypeScript error:

Failed to compile.

undefined
TypeScript error in undefined(undefined,undefined):
File name '/path/to/file/MyFileName.types.tsx' differs from already included file name '/path/to/file/myFileName.types.tsx' only in casing.  TS1149

Spot the difference in first letter between myFileName and MyFileName. I have not idea how this happened and I don't know how to fix it. I have never seen this error before. I am using TypeScript Version 3.5.3. If someone can at least point me into direction what to do, it would be super helpful.

Solution

  • Oh crap. There was a lowercased import somewhere in my code:

    import { TSomething } from './myFileName.types'

    while real file name was uppercased:

    MyFileName.types.tsx

    I still don't know why TypeScript compiler didn't tell me where was that.
