How to correctly import operators from the `rxjs` package

Question

I am confused how to import those operators. Some I can import with import \'rxjs/add/operator/do\'; and some I can not. For ex, this does not work: impo

Answer 1

Lower version of rxjs has got folder

node_modules\rxjs\operator

Higher version of rxjs has got folder

node_modules\rxjs\operators

Please make sure the typescript file location is exists for map and other operators exists within.

If problem still persist please delete rxjs folder from node_modules and run the command

npm  install --save 

usually this causes due to lowering the package version from higher version of rxjs.
