Cannot find name
Cannot find name 'Missing'.The compiler’s own words. Not translated — this is the string you pasted into a search box.
The compiler looked for this name in every scope it can see and found nothing. Usually a typo, an unimported type, or a value being used where a type belongs.
Reproduction
type A = MissingThe build asserts this emits exactly this code.
Why the compiler says this
Types and values live in separate namespaces, and this error is often the seam between them. A `const` called `config` is not a type called `config`, and asking for one where the other exists produces exactly this message — which is why the fix is sometimes not "define it" but "ask for its type instead".
Fixes
- 01
type Missing = string type A = Missing
Define it, if it genuinely does not exist yet.
- 02
const config = { retries: 3 } type A = typeof config
Or reach across the namespaces with `typeof`. The name existed all along — as a value — and `typeof` is how you ask for the type of one.
Takeaway
Before defining the missing name, check whether it already exists on the other side of the type/value divide. `typeof` crosses it in one direction and `keyof` walks what you find there.
