C:\Users\armyTik\Desktop\angular2_projects\1>ng new pro-name

 the graceful-fs module, please update it to a more recent version.

  • is this error occurs only while installing `angular-cli` package or for all packages. It clearly says there is some problem with your `global` directory path. – Venkata Dorisala Jul 07 '16 at 13:45

  • The only steps I did is to create an empty folder and run inside 'npm install -g angular-cli'. – Stav Alfi Jul 07 '16 at 13:49
  • can you try instlalling other packages. like `npm install -g jquery` – Venkata Dorisala Jul 07 '16 at 13:51
  • also you don't have to go to empty directory to run this command. You can run it anywhere. It just installs the packages in the `global` path configured. Default is `C:\AppData\Roaming\npm\node_modules\` – Venkata Dorisala Jul 07 '16 at 13:52
  • 'npm install -g jquery' installed! Anyways while installing npm install -g angular-cli , It says during installtion: "still install loadAllDepsIntoIdealTree". Is this the reason for the problem? – Stav Alfi Jul 07 '16 at 13:57
  • The `angular-cli` documentation talks about some `prerequisites : Node 4 or greater, Typings V1 or greater` . Make sure you have these installed already. https://github.com/angular/angular-cli#prerequisites – Venkata Dorisala Jul 07 '16 at 14:01

  • when did u get this error? after installing angular-cli ? or during? – Venkata Dorisala Jul 07 '16 at 14:08
  • after installinh -g angular-cli , I tryied to make new project by doing: "ng new project-name" and it failed with this error: "You cannot use the new command inside an angular-cli project.". – Stav Alfi Jul 07 '16 at 14:10
  • i think you need to run `ng new project-name` command from the root directory. Not inside the angular directory. – Venkata Dorisala Jul 07 '16 at 14:13
  • many thanks for your help but this problem has not been solved yet. :( – Stav Alfi Jul 07 '16 at 14:19

Make sure you have prerequisites installed on your machine.

angular-cli needs Node 4 or above & Typings V1 or greater

node -v should be greater than 4

node typings -v should be greater than 1

otherwise install typings using npm install typings -g

If you are on a mac don't forget sudo in front of the command
