Having same issue

[bohms27]

Do you also have it installed locally? I had it installed globally and locally and received the error. Uninstalled the local version in the folder and it worked fine.

[vladiRoz]

I created a new folder and tried to sudo ng new PROG....
do you create a package.json? before the new?

[bohms27]

Nope I didn't have it created before

See https://github.com/angular/angular-cli#prerequisites

You need at least npm3 to run the CLI. I suggest installing Node 6 which comes with npm 3.

[adesugbaa]

I have npm3 and node 5/6. It gives the same errors above.

[vladiRoz]

I installed the prerequisites, latests npm and node (tried with all available versions).

[tamdao]

I have npm 3.x and node 6.x. But I have the same issue

@filipesilva - I have npm 3.10.8 and have the same issue. Maybe this project just doesn't work on Node 4.5?

[sebge23]

I have the same issue and i found this question on stackoverflow.

Workaround: #2355

[vadost]

Simplest workaround to continue working in your project is comment line 25 of node_modules/angular-cli/bin/ng :
// Version.assertPostWebpackVersion();
Until it is fixed properly.

[filipesilva]

Really fixed in #2178
