firstly changed in package.json rxjs oldest versione rxjs “6.0.0-rc.0” and then run npm install rxjs-compat --save

@nhhockeyplayer see what the new import paths should be here.

@nhhockeyplayer

As @samherrmann pointed out, the import paths you specified are incorrect, ‘rxjs/Observable’ becomes just ‘rxjs’.

@rahulbhooteshwar

I would make sure your dependencies are cleanly upgraded, by this i mean delete your package-lock.json and your node_moduels directory and redo your npm install command, i’ve had issues in the past with packages not actually installing correctly because the package-lock.json file has an old version of packages in it.

for me this didn’t work yet, as I struggle with
