TS5053

Option '{0}' cannot be specified with option '{1}'.

Two compiler options that conflict are both set in tsconfig.json. Remove one of them.

What it means

The two options in the message can't be used together; they ask for incompatible behaviour. ts_r_config detects this, but ts-r-check doesn't print program-level option checks yet, so running it on such a config shows no error today.

How to fix

  • Remove one of the two options from tsconfig.json.
