Hello,

Please provide a little bit more context on your problem, mentioning which version of typescript, ts-jest and nodeJS you are using, and also your current jest config file.

Thanks,

EphraimB commented 1 year ago

I'm using the latest lts version of everything. I'm not near a computer now to post the jest config file.

ThomZz commented 11 months ago

Please post the jest.config.(ts/js)

EphraimB commented 11 months ago

import type { JestConfigWithTsJest } from 'ts-jest' import { defaults } from 'jest-config';

const jestConfig: JestConfigWithTsJest = { ...defaults, preset: 'ts-jest/presets/default-esm', testEnvironment: 'node', transform: { '^.+\.(t|j)s$': ['ts-jest', { tsconfig: './tsconfig.test.json', useESM: true }] }, moduleNameMapper: { '^(\.\.?\/.+)\.js$': '$1' } };

export default jestConfig;

And if you add the ast transformer, it fails with the aforementioned error ? I would like to see the complete jest.config, including the ast-transformer configuration, for wich you can replicate the error.

same issues with esModule project.

if I remove the dirname or filename var in my code it works. Then obviously my code is broken when I run it normally in ts-node etc.

ts-jest seems to have a different environment than whats setup in the ts-node when I run the code.

bulkbeings-admin commented 3 months ago

@null-prophet were you able to figure out a way for this?

EphraimB commented 3 months ago

I chose a different solution in the end
