same issue here. the little info I found on errors like this said you could ignore them but that does not seem to be correct as npm install stops at that point. when I ran ng new it immediately errored out stating could not find portfinder and am unable to run npm install on angular-cli as I get the error mentioned in the original post.

Same problem solved by using NPM3 for me

[quzaq]

I had the same problem trying to upgrade from angular-cli: 1.0.0-beta.10 to angular-cli@webpack

My environment: node v4.5.0, npm 2.15.9, Ubuntu 14.04.

Resolved when upgraded to node v6.4.0, npm 3.10.3.

After successful installation I've seen only following text in red:
├── UNMET PEER DEPENDENCY typescript@2.0.0

So loosely related to #1737 and #1046.

@davinkevin's method worked for me -- I used the npm3 package and it installed as admin under Windows x64.

[filipesilva]

The problem is that NPM3 is needed, yes. It's not currently mentioned on the readme but #1748 adds that.

[akashgill1687]

how to use npm3 ?
could you please provide some steps ?

[amellnik]

@akashgill1687 npm install -g npm3 and then use npm3 in place of npm to install or just update npm to the latest version.

[akashgill1687]

cool it worked . i updated my npm . now can i upgrade my new project created with angular cli to to rlc5 ? and use rlc5 features ? if yes could you please jot down some steps for that please ? Thanks a lot

[akashgill1687]

i would like to add rlc5 features like aot ?

[filipesilva]

We don't currently support AOT but are working to get that into the CLI. To update NPM, see http://stackoverflow.com/a/6237400/2116927

[akashgill1687]

alright but can i use this compiler with cli@webpack : https://github.com/angular/angular/tree/master/modules/%40angular/compiler-cli

[akashgill1687]

i ended up this issue :

Angular 2 rlc5 with angular-cli errors while ng serve

[filipesilva]

We don't currently support it so I don't think that'll work.

install node v6.4.0 manually from https://nodejs.org/en/ @19390917 is right.
