I’ve created a new Typescript project using

mkdir zod-ts
cd zod-ts
npm init // all options default
npx tsc init

This creates the following tsconfig.json

target: es2016
module: commonjs
strict: true
esModuleInterop: true
skipLibCheck: true
forceConsistentCasingInFileNames: true

I install zod and other packages with npm install zod @types/node typescript

I then create an index.ts file with the following code

import { z } from "zod";
const myType = z.object({
    myprop: z.string().optional(),
});

console.log(myType);

I then run tsc index.ts and I’m greeted with the following error: node_modules/zod/lib/types.d.ts:777:5 - error TS18028: Private identifiers are only available when targeting ECMAScript 2015 and higher.

As skipLibCheck: true I’d expect it to ignore this, but it’s not.

What am I doing wrong here?
