I am trying RxJs7 in my angular 12.2.0 project and it seems like the path of rxjs operator and method changed.
I am getting the below error
./dist/candypal/website/fesm2015/candypal-website.js:8:0-50 - Error: Module not found: Error: Package path ./index is not exported from package /Users/aniruddh/aniruddh/develop/experiment/candypal/node_modules/rxjs (see exports field in /Users/aniruddh/aniruddh/develop/experiment/candypal/node_modules/rxjs/package.json)
Note that the above error is coming from a library that uses rxjs7
In your code, replace
import { Whatever } from 'rxjs/index'
by
import { Whatever } from 'rxjs'
The rxjs/index folder was removed from rxjs.
