Doing this worked for me. Thanks to @dharders

i.e.

find ./node_modules -type d | grep "/rxjs$"

./node_modules/@angular/cli/node_modules/rxjs
./node_modules/@angular/core/node_modules/rxjs
./node_modules/@angular/http/node_modules/rxjs
./node_modules/@angular/router/node_modules/rxjs
./node_modules/rxjs

Then after manual deletion of sub-directories:

find ./node_modules -type d | grep "/rxjs$"

./node_modules/rxjs

Then ng new works without any problems.

@yeshesvi Thanks for your example, your solution works for me. I delete duplicated rxjs folders and files. Then issue is solved.
