描述

Attempting to change the declaration file output directory, I get the following error:

error TS5053: Option 'declarationDir' cannot be specified with option 'outFile'.

tsconfig.json looks like this:

{
    "$schema": "http://json.schemastore.org/tsconfig",
    "compilerOptions": {
        "module": "amd",
        "target": "es6",
        "outFile": "../assets/js/main.js",
        "sourceMap": true,
        "declaration": true,
        "declarationDir": "../"
    }
}

I want my .d.ts file emitted somewhere else, since that's not a public asset.

Why is this not permitted?

I'm forced to create two (near-identical) tsconfig files and run the compiler twice to get the declaration file and output file. What for?

研究方向
This feature request asks to allow `declarationDir` when `outFile` is set. Currently, the TypeScript compiler shows error TS5053 preventing this combination. To implement this, a contributor should examine the compiler's option validation logic, likely in `src/compiler/commandLineParser.ts` where incompatible options are checked. They need to understand the technical reason for the restriction (possibly related to AMD module output) and modify the validation to allow it while ensuring correct behavior. No maintainer response or linked PRs exist, so the contributor must infer requirements from the issue description and codebase.
