Compile fails on Angular 8 with enableIvy:true

[abbas999]

Build a project that uses angular-ab-tests on Angular 8 after adding

"angularCompilerOptions": {
  "enableIvy": true
}

to tsconfig.app.json. Compile fails with the following error:

ERROR in ENOENT: no such file or directory, open '/my_angular_project/node_modules/angular-ab-tests/angular-ab-tests.js'

This is because package.json mentions

"module": "angular-ab-tests.js"

while no such file exists. If I manually change angular-ab-tests.js to index.js, all works fine.

Hi @abbas999, thank you for pointing this out, I'll fix it ASAP

Hey there,

I just created an empty Angular8 project, installed angular-ab-tests, and enabled Ivy compiler.

I don't get the error you mention, but I get instead an error related to @ngx-utils/cookies

ERROR in ./node_modules/angular-ab-tests/__ivy_ngcc__/fesm5/angular-ab-tests.js 749:16-30
"export 'CookiesService' was not found in '@ngx-utils/cookies'
ERROR in ./node_modules/angular-ab-tests/__ivy_ngcc__/fesm5/angular-ab-tests.js 752:227-241

Module not found: Error: Can't resolve './src/cookies-options.service' in '/Users/adriano/Documents/Boat International/Progetti/beppe/node_modules/@ngx-utils/cookies/__ivy_ngcc__'
ERROR in ./node_modules/@ngx-utils/cookies/__ivy_ngcc__/index.js
Module not found: Error: Can't resolve './src/cookies.service' in '/Users/adriano/Documents/Boat International/Progetti/beppe/node_modules/@ngx-utils/cookies/__ivy_ngcc__'

The module @ng-utils/cookies was introduced as a dependency to make Angular Universal work. I installed the previous version of angular-ab-tests by running

npm install angular-ab-tests@"<1.3.0"

and the compilation worked fine.

Now, I have got two problems:

• First, how to reproduce the error you experienced, since I couldn't see it
• Second, why you didn't see the problem with ng-cookies? Maybe that would have occurred if your Ivy compiler had succeeded finding angular-ab-tests?

I'm seeing the issue you pointed out now too. I've been following discussions on angular bugs and it seems like a lot of these issues can be resolved by using ng-packagr (https://github.com/ng-packagr/ng-packagr) to push to npm. Do you use ng-packagr?

[adrdilauro]

I am already using ng-packagr. It's possible though that the latest version of ng-packagr tackles different issues that are relative specifically to the Ivy compiler, this evening I'll try to download the latest version of ng-packagr and pack the module again, I'll keep you updated.

How did you resolve the first problem you had experienced? The missing index.ts file?

There is a problem with @ngx-utils/cookies, I opened this issue in their repo and asked them for clarifications. You can look at the issue and if you have any ideas please let me know.
