angular-cli: Cannot initialize a new project after installing angular/cli 1.4.7 - Error: tree.branch is not a function

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.

tree.branch is not a function is being worked on, but in the meantime I can tell you why it happens; you have two different RxJS installed in your node_modules, and your schematics is using one while the CLI is using another. Check your dependencies with npm ls

@rolandoesc found a solution…
