TS2305: Module has no exported member - in CI

By Daniel Zoghalchali·Latchkey

You imported a named export that does not exist on the target module.

What this error means

Type-checking fails with TS2305 naming the member and the module it is missing from.

src/util.ts(2,10): error TS2305: Module './helpers' has no exported member 'formatDate'.

Common causes

How to fix it

Import the correct exported name

1. Open the module and confirm the exact export name
2. Update the import to match

import { formatDate } from './helpers'

Align the dependency version with its types

1. Match the package and its @types major versions
2. Reinstall from a clean lockfile

npm ls some-pkg @types/some-pkg

How to prevent it

• Pin dependencies and their @types together, and rely on editor autocomplete to import real export names.
