ERROR in node_modules/ngx-papaparse/lib/papa.d.ts:5:22

Cannot use ngx-papaparse with angular 9+
Already ran npm install papaparse@5.2.0

ERROR in node_modules/ngx-papaparse/lib/papa.d.ts:5:22 - error NG6002: Appears in the NgModule.imports of AppModule, but could not be resolved to an NgModule class.

This likely means that the library (ngx-papaparse) which declares Papa has not been processed correctly by ngcc, or is not compatible with Angular Ivy. Check if a newer version of the library is available, and update if so. Also consider checking with the library's authors to see if the library is expected to be
compatible with Ivy.

5 export declare class Papa {

Hi.

Sorry for the late reply. I have just released a new version (ngx-papaparse@5) which should solve this issue. If not, feel free to reopen this issue.

[AlexGoris-KasparSolutions]

I'm having this exact problem still today with Angular 10.2.3 and ngx-papaparse@5.
Should I open a new issue or can this one be reopened?

[alberthaff]

@AlexGoris-KasparSolutions No need for a new issue, if it's the same problem.
Could you please send me the versions stated in your content package.lock-file?
I need the version of ngx-papaparse, papaparse and @angular/core.

Also - do you have ivy enabled?

[AlexGoris-KasparSolutions]

I have Ivy enabled, yes, I believe it's also the default in angular v10/11

Found this in package-lock.json:
