[ERR_PACKAGE_PATH_NOT_EXPORTED] when running ng e2e

[dmdum]

Hello, trying to use cucumber with protractor in angular.
When running ng e2e --port 4201 I get an error:

E/launcher - Error: Error [ERR_PACKAGE_PATH_NOT_EXPORTED] [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './package.json' is not defined by "exports" in C:\Users\dndum\Documents\Projects\angular-project\node_modules@cucumber\cucumber\package.json

Please advise on how to proceed.
Thank you!

Hi,

Thank you for your report.

With v8.0.0-rc.1 and the ESM support, indeed package.json is not exported anymore. I will take a look on that to see if we can add it to the exports.

This is actually related to that: #1853
serenity-js wants to check the version number from the package.json.
It is difficult to ask them to do otherwise as this is within a generic module loader: https://github.com/serenity-js/serenity-js/blob/master/packages/core/src/io/ModuleLoader.ts#L79

Hello,

Thank you for responding.
Will be using 7.3.1 instead.
Cheers!

[aurelien-reeves]

@dmdum would you have the possibility to test with the following branch: #1870?

You should be able to do that with the following:

npm install https://github.com/cucumber/cucumber-js#export-package-json-again

Important: do not use that branch in production. This is just for testing purpose! 😅

[dmdum]

I might be able to after work hours. I'll post here whatever I find.

[dmdum]

Hey, sorry for the delay. Been busy the past couple of days. I tried installing today but I got this error.

[aurelien-reeves]

Hey :)

Indeed, the branch has been merged on main.
Could you try npm install https://github.com/cucumber/cucumber-js?

[dmdum]

Got another error

[aurelien-reeves]

Yes
I have suggested a totally wrong command 😑
It won't be as easy as I though because the package needs to be built. So, unfortunately you won't be able to test it before we release it.

Sorry for that 😓

[dmdum]

Oh, no worries. Btw, I'm actually still learning cucumber and I was wondering if I can use it on Angular alone without Protractor. Would that be possible? I've been looking for a setup guide on how to do that but Cucumber always seems to be paired with something...

[aurelien-reeves]

Actually I don't know Angular or Protractor.
Cucumber can work on its own, it does not need to be coupled with something else.

But maybe Angular itself requires Protractor?

[dmdum]

Hmmm, yeah maybe that's it, thanks.

Protractor is (or was when I last used it) essentially a wrapper around WebDriver that had special handling for Angular's event loop etc.

You could definitely test an Angular app with Cucumber paired with WebDriver, Puppeteer or Playwright.

There's an example here with Puppeteer (not an endorsement of that over any of the other options, just something I've used).
