Angular CLI ng new error

Question

I've installed node from https://nodejs.org/en/download and then I installed angular CLI via NPM using

npm install -g @angular/cli

After it's done, I then try to create a new angular project

ng new new-project

And I get the following error

Error: You provided an invalid object where a stream was expected.
  You can provide an Observable, Promise, Array, or Iterable.

I've tried installing the cli using sudo (and without) and I've reinstalled node: I always get the same error.

I can't find anything about anyone having this issue.

I'm using MacOS.

Answer 1

I follow the steps

• Update Node, npm latest version
• Remove angular-cli 1.6.3
• Install angular-cli 1.5

I could create application, component and others

updated 12-JAN

I update angular-cli up 1.6.4, Node up 9.4.0 and worked fine for me to create new project

Answer 2

Try to use an older version of Angular CLI until this problem get solved.

You can follow this issue in https://github.com/angular/angular-cli/issues/9172.

EDIT: I found a solution, run these commands:

npm un -g @angular/cli
npm cache clean --force
npm i -g @angular/cli

It worked for me.

Issue has been fixed.

Remove node_modules and run npm install to get the latest dependencies.

Confirmed issue on:

Angular CLI: 1.6.3 Node: 6.10.3 OS: win32 x64

Angular CLI: 1.6.3 Node: 6.10.3 OS: linux x64

Angular CLI: 1.6.4 Node: 8.0.0 OS: win32 x64

In each cases i'm using nvm.

Works after uninstalling and specifically installing angular cli version 1.5.5
