Error: Note that you need plugins to import files that are not JavaScript

This error happens whenever trying to use dts() in a project which has a tsconfig.json file with "noEmit": true, specified.

Possible related to rollup/plugins#287

Hm, we possibly have to override that option here:

rollup-plugin-dts/src/program.ts

Lines 12 to 27 in b92324d

	const OPTIONS_OVERRIDE: ts.CompilerOptions = {
	// Ensure ".d.ts" modules are generated
	declaration: true,
	// Skip ".js" generation
	emitDeclarationOnly: true,
	// Skip code generation when error occurs
	noEmitOnError: true,
	// Avoid extra work
	checkJs: false,
	declarationMap: false,
	skipLibCheck: true,
	// Ensure TS2742 errors are visible
	preserveSymlinks: true,
	// Ensure we can parse the latest code
	target: ts.ScriptTarget.ESNext,
	};

Can you give a more detailed example? I suspect you are using the plugin with .ts files?

That did the trick. Thanks 😄
