The error is:

Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: D:\GITHUB\necter-backend\node_modules\wrap-ansi\index.js

Does it say which module you're trying to require that is ESM?

ornate coral Does it say which module you're trying to require that is ESM?

I think is wrap-ansi
Full version of errror log

Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: D:\GITHUB\necter-backend\node_modules\wrap-ansi\index.js
require() of ES modules is not supported.
require() of D:\GITHUB\necter-backend\node_modules\wrap-ansi\index.js from D:\GITHUB\necter-backend\node_modules\cliui\build\index.cjs is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules.
Instead rename index.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from D:\GITHUB\necter-backend\node_modules\wrap-ansi\package.json.

Oh interesting. I'm pretty sure that's a package from @nestjs/cli and wouldn't expect there to be a break in it

abstract moth Jul 2, 2023, 5:25 PM

#

I think i should upgrade the cli

ornate coral Jul 2, 2023, 5:25 PM

#

What's your CLI version?

abstract moth Jul 2, 2023, 5:28 PM

#

9.1.5 current

ornate coral Jul 2, 2023, 5:32 PM

#

That should be fine. Any chance you can provide access to your repo?

abstract moth Jul 2, 2023, 5:33 PM

#

This is private project, but i can share some part of it

#

which one do you need

ornate coral Jul 2, 2023, 5:33 PM

#

I would need a way to reproduce the error

abstract moth Jul 2, 2023, 5:34 PM

#

Well, i error when i ran the test script

#

there nothing more config

ornate coral Jul 2, 2023, 5:35 PM

#

Great then you should be able to reproduce this without the private parts, right?

abstract moth Jul 2, 2023, 5:35 PM

#

Oh, i know, the project take the boilerplate code from https://github.com/pejmanhadavi/real-world-example-nestjs-mongoose-jwt-auth

📎 package.json

#

i think this is enough to reproduce the error

ornate coral Jul 2, 2023, 5:41 PM

#

I can't even install the base repo. Something in node-gyp is 404ing

#

Let me downgrade my node version. Might be an issue with v20

#

Yep, node 20 issue. Weird

abstract moth Jul 2, 2023, 5:43 PM

#

18.13 and 14.21 is fine

ornate coral Jul 2, 2023, 5:43 PM

#

All right, so install, and just run test?

abstract moth Jul 2, 2023, 5:43 PM

#

Yeah

ornate coral Jul 2, 2023, 5:47 PM

those are e2e tests, and for that test:e2e should be the ran script
there's alreayd an e2e spec file
I get this error instead of the one you're getting:

abstract moth

have you use the package file

ornate coral Jul 2, 2023, 5:52 PM

#

Even with your package.json I'm not getting that error

abstract moth Jul 2, 2023, 5:53 PM

#

I will tried to delete the nodemoduke

ornate coral Jul 2, 2023, 5:53 PM

#

So what you're calling a minimum reproduction isn't. I would need an actual reproduction to help debug this further

abstract moth Jul 2, 2023, 5:55 PM

#

Okay, let me see what i can do to give u some code

#

weird, after delete all resource in /src no error was throw

#Cannot run jest test, got Error [ERR_REQUIRE_ESM]:
