1. Mention any other details that might be useful.

Tried to init a project (ng init).
Installed locally in the project's directory (npm i angular-cli@webpack)

Thanks! We'll be in touch soon.

I'm also getting this same issue (on a mac) after updating to the angular-cli webpack version following the steps here:

https://github.com/angular/angular-cli/blob/master/WEBPACK_UPDATE.md

1. Mac - El Capitan version 10.11.5
2. Same as above, running ng --version causes the same error, node version is: v5.4.0
3. Just running: ng new test
4. Same stack trace as above.

Thanks

Just playing around - I updated process-nextick-args, that is a dependency of readable stream from 1.0.6 to 1.0.7 and this fixed the issue for me.

[monojack]

Update npm to version 3.x.x

[sculove]

I solved it.
I install some modules manually.

npm i process-nextick-args util-deprecate

[bthharper]

I am getting this error too after a fresh install of angular-cli@webpack and then running any ng command.

I have used the above trick, but had to globally.

npm i -g process-nextick-args util-deprecate

[ribizli]

@sculove yes, this solution works for me too, but this seems to be a bug in the dependency hierarchy of angular-cli.

[monojack]

have you tried my solution before downvoting? that's how I fixed it. You don't need to bloat-up you global packages. ;)

[bthharper]

I'd already checked my version of npm, and was already running a variant of version 3. Did check though. The workaround proposed by @sculove (with a slight modification to do it globally) worked for me, but as @ribizli states this is a bug in the dependencies which has crept in somewhere.

[mdocter]

Even ng --version threw this error. Globally installing the process-nextick-args and util-deprecate packages didn't fix it for me. I'm running on Windows 10 (x64), so I had to cd into /c/Program Files/nodejs/node_modules/angular-cli and npm install both packages there locally, so without the -g flag :-).

[rbj325]

Upgrading Node.js to 6.5 and reinstalling angular-cli also fixes this.

[filipesilva]

Looking into it myself.
