angular-in-memory-web-api   version 0.6.0 works with RxJS v6

Check your RxJS version in package.json

You can solve your error by using angular-in-memory-web-api   version 0.5.4

Use following command:

npm uninstall angular-in-memory-web-api --save

npm i [email protected] --save

Reference:


0.6.0 (2018-03-22)

Migrate to Angular v6 and RxJS v6

Note that this release is pinned to Angular "^6.0.0-rc.0" and RxJS "^6.0.0-beta.1". Will likely update again when they are official.

BREAKING CHANGE This version depends on RxJS v6 and is not backward compatible with earlier RxJS versions.
