The problem seems to be is with the version. I was using some other plugin and was having the same issue. After downgrading the version of the plugin it started working.

[loveneetchahal]

npm install rxjs@6 rxjs-compat@6 --save

If it is a compatibility issue, can someone please explain the correct way to handle the operators? map, catch, etc

I came across this issue after upgrading node and npm. Running ng serve would throw this error.
I deleted node_modules folder and did an npm install. While running npm install got another set of errors which required me to install ms build tools and to do few system configuration changes. Once the npm install ran successfully, the issue with ng serve also got fixed.
