Yeah, it worked for me as well, I hope someone can give us an idea of how to solve it without any "workaround". Thanks for your help! :)

I am having the same error pop up since upgrading to CLI 1.4.7. I've been trying to create new components and services though, not just new apps and projects.

System:
@angular/cli: 1.4.7
node: 6.10.3
os: win32 x64

C:\Project>ng generate service services/test-service Error: tree.branch is not a function tree.branch is not a function

[wvicioso]

Same issue.

@angular/cli: 1.4.5
node: 6.11.4
os: win32 x64

I tried tried install globally. When I try to initialize a new project I get Error: tree.branch is not a function

[krishnabangalore]

same issue here as well but on Linux

did anyone solve it
I tried to generate a component
ng generate component component-name

and got errors
Error: tree.branch is not a function

[hansl]

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

[phippsbd1]

@hansl Thanks for the tip. I dumped my node_modules folder and reinstalled and that fixed the error.

[patocardo]

After several different attempts, I couldn't make cli works. The workaround I found is to clone the quickstart, and use the npm scripts instead of ng.

[rolandoesc]

I know this isn't a solution to the case, but I changed my Ubuntu shell and everything went perfectly.

In my situation, I was using LTS 16.04 with GNOME when this happened, but now I'm using LTS 16.04 with Unity Shell.

I hope this helps in order to find a solution.

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.

@yeshesvi
thank you for your effort .
but still didn't work for me .

@Callie-C-Wang

$ find ./node_modules -type d | grep "/rxjs$"
./node_modules/rxjs
$ cd Projects/
Projects$ ng new firstangapp
Error: tree.branch is not a function
tree.branch is not a function

@powerfulman86
My system is Microsoft Windows [Version 6.1.7601]
