Mention any other details that might be useful.

Thanks! We'll be in touch soon.

iains-iMac:git iain$ ng --version

EDIT : Looks like i was on an outdated NodeJS version. My bad. Worth running 'node -v' first next time :)

@danny-36 Exact same error, except I'm not trying to install globally like you. My command differs from you just because yours have the -g flag/option. Out of that, the error here are pretty the same as yours:

@MAJLGC sometimes is the simple error message that gives it away! I did the same thing and it resolved my issue. I am on OSX. Thanks for posting.

shawnvoseRP on 28 Feb 2017

@MAJLGC acknowledge,
for me npm install -g rxjs@^5.0.1 then npm install -g @angular/cli results in no peer dependency warnings.

@MAJLGC Globally installing rxjs and @angular/cli worked for me too. Thanks!

UlyssesAlves on 1 Mar 2017

Same issue here:
El Capitan 10.11.6
Node 6.9.5
NPM 3.10.10

Installing rxjs fixed..

avalonabecker on 1 Mar 2017

Fixed in newer releases. There should be no peerdep problems anymore. Sorry about that.

├── UNMET PEER DEPENDENCY @angular/[email protected]
├── UNMET PEER DEPENDENCY @angular/[email protected]
└── UNMET PEER DEPENDENCY @angular/[email protected]

but after checking the ng --version i get :
@angular/cli: 1.0.0
node: 7.7.2

@angular/common: 2.4.10
@angular/compiler: 2.4.10

@angular/platform-browser-dynamic: 2.4.10
@angular/router: 3.4.10
@angular/cli: 1.0.0
@angular/compiler-cli: 2.4.10

i think it is an update issues of separate packages or Modules!!!

I think we should completely uninstall angular cli globally and install the latest version using @latest suffix.

rinoldit on 28 Mar 2017

Ok @angular/cli install version 1.0.0.xxx but still command ng opens just some kind of VIM (and it dont want to close normally, normal vim closes normally).... so I can't open ng new etc (linux mint 18.1) ... so annoying.

Uh, something odd here...

juha@juha-PC-Mint ~ $ ng -v
Mg++ version:
Mg++ 1.5beta1 (formerly MicroGnuEmacs Adv.)

Ok removed that. Solution was that my Path to node-global was missing. So now we can start to practice.

@filipesilva "There should be no peerdep problems anymore."

I'm still getting the "npm WARN @angular/[email protected] requires a peer of rxjs@^5.0.1 but none was installed" error, even after installing angular-cli@latest. Am I missing something or do I still need to install rxjs manually?

ryanaltvater on 3 Apr 2017

@filipesilva Never mind...installing @angular/cli is the new way to go and does not give that error. My mistake. :)

ryanaltvater on 3 Apr 2017

I'm also having this issue, but additionally am getting an empty response. Any ideas on what the `-- (empty) means or how to fix? Thanks.

SarahWallis on 24 Apr 2017

I had the same thing. Found out it was because I updated some of the @angular/ packages and not others. My fix was deleting the node modules folder and running npm install again. My issue was in relation to not knowing or having a good way to update and I found/like this feature request: https://github.com/angular/angular-cli/issues/5919 Which is about having some way to let developers know about new version releases and a quick and easy way to upgrade like with ng update

canada11 on 4 May 2017

Just follow update guide https://github.com/angular/angular-cli#updating-angular-cli

I've tryed with "npm install" but goth that error;
Finally after using "npm prune" worked fine the "npm install" and I could install angular 4.

shivshaktiss17 on 14 Jun 2017

@shivshaktiss17 The worse case, try to remove node_modules folder and again "npm install". Probably there is still something cashed.

linuradu on 14 Jun 2017

I'm getting the same error. I installed @angular/[email protected] and did rm -rf node_modules and npm install

@angular/[email protected] has a peer dependency issue that is being tracked in https://github.com/angular/angular-cli/issues/7078. Please subscribe to that thread for updates specific to this version.

filipesilva on 21 Jul 2017

can anyone help? Even though i have installed @angular/cli latest still giving error on UNMET PEER DEPENDECIES ISSUSE!

KhizerRehan on 26 Jul 2017

@KhizerRehan there is no peer-dependency issue with @angular/cli itself currently. The peer dependencies you have right now are due to your project dependencies.

You should read through the errors that NPM shows you and provide the appropriate peer dependencies in package.json. You can read more about it https://nodejs.org/en/blog/npm/peer-dependencies/.

filipesilva on 27 Jul 2017

same error :(((

ssalehi on 8 Aug 2017

I faced same error
Below steps helped me. I hope these will help you also

npm update
npm uninstall -g angular-cli

Hi @tankala,
Did you tried to add in:

"dependencies": {
    ...
    "@angular/compiler-cli": "4.1.0",
}

and

"devDependencies": {
    ...
    "@angular/cli": "1.2.1",
    "@angular/compiler-cli": "4.1.0"
}

afterwards to run:

npm prune
eventually: npm cacle clean
and: npm install

Please let me know is this is working for you.

linuradu on 9 Aug 2017

Hi @linuradu ,

I think I didn't typed properly. I got this problem and I solved this problem by using these steps

npm update
npm uninstall -g angular-cli
npm cache clean
npm install -g @angular/cli

tankala on 9 Aug 2017

Yea! Had this issue on Ubuntu but running npm update seems to have fixed it.

pstephenwille on 5 Nov 2017

It worked with
First

sudo npm prune rxjs angular/cli OTHERs

Second

sudo npm i -g rxjs angular/cli OTHERs
