TS6053: File not found - in CI

By Kaveh Alemi·Latchkey

tsc was told to compile a specific file that does not exist at the given path.

What this error means

tsc fails with TS6053 naming a path from the files array, an extends, or a reference that is missing.

error TS6053: File '/app/src/main.ts' not found.

Common causes

How to fix it

Fix the path in tsconfig

1. Update the files entry to the real path with exact casing

{
  "files": ["src/main.ts"]
}

Ensure the file is present in CI

1. Confirm the checkout includes the path; avoid sparse checkouts that drop it

ls -la src/main.ts

How to prevent it

• Keep tsconfig files entries current and verify CI checks out all referenced source paths.
