Duplicated @types in typescript libs (index.d.ts - Duplicate identifier) for jasmine, jasminewd2, mocha

I've got jasmine, jasminewd2 and mocha in my Angular project. Those libs have index.d.ts files which seems to be duplicated. Is it some way to avoid this error? Since my Visual Studio cannot build it. I was already trying to exclude those files in my tsconfig.json file, upgrading version ain't helping as well.

Solution

  • Thanks to JimiPajala we have solution.

    I've added "skipLibCheck": true, to tsconfig.json

    Regarding to documentation: "Skip type checking of all declaration files (.d.ts).*" https://www.typescriptlang.org/docs/handbook/compiler-options.html
