[Bug]: ts-jest[ts-compiler] (WARN) Unable to process '/node_modules/.pnpm/[email protected][email protected]/node_modules/wouter/esm/index.js', falling back to original file content. You can also configure Jest config option transformIgnorePatterns to ignore /node_modules/.pnpm/[email protected][email protected]/node_modules/wouter/esm/index.js from transformation or make sure that outDir in your tsconfig is neither '' or '.'

Version

29.2.5

Steps to reproduce

Clone https://github.com/Grsz/ts-jest-repro
Run pnpm i
Run pnpm test

Expected behavior

It should transform the js file from wouter using import.

Actual behavior

/node_modules/.pnpm/[email protected][email protected]/node_modules/wouter/esm/index.js:1
    ({"Object.<anonymous>":function(module,exports,require,__dirname,__filename,jest){import { parse } from 'regexparam';
                                                                                      ^^^^^^

    SyntaxError: Cannot use import statement outside a module

I have the same problem, since updating to 29.2.5 running tests with jest fails on:
/node_modules/react-dnd/dist/index.js:2
export * from './core/index.js';
^^^^^^

SyntaxError: Unexpected token 'export'

This issue seems related to #4561

Are you using typescript version 5.6?

[jklepek-vendavo]

Yes, I am using version 5.6.2. But I solved the issue by migrating from jest to vitest.

+1 on this issue with TS 5.6.3 initialising ts-jest using the command: npx ts-jest config:init

This is my tsconfig:

{
    "compilerOptions": {
        "esModuleInterop": true,
        "skipLibCheck": true,
        "target": "es2022",
        "allowJs": true,
        "resolveJsonModule": true,
        "moduleDetection": "force",
        "isolatedModules": true,
        "strict": true,
        "noUncheckedIndexedAccess": true,
