💻 Code

const TS = require('typescript')

const res = TS.transpileModule('export const x = 6;', {
    fileName: 'test.d.tsp.ts',
});

console.log(res)

🙁 Actual behavior

The Typescript compiler crashes. The compiler should allow files that contain .d. in their name.

🙂 Expected behavior

The compilation succeeds

Commencez par la reproduction de TS.transpileModule dans l’issue, en utilisant le nom de fichier test.d.tsp.ts et les versions de TypeScript indiquées. Comparez le chemin de génération de sortie qui échoue avec l’ancienne version qui fonctionne et ajoutez un test de régression pour les noms de fichier contenant .d. ; le travail est terminé lorsque la transpilation réussit avec une sortie et sans plantage.
