Installing Angular CLI (angular-cli@1.0.0-beta.16) via npm install -g angular-cli@latest failed with the following error in npm-debug.log:

Error: The package webpack@2.1.0-beta.22 does not satisfy its siblings' peerDependencies requirements!

Solution

  • Upgrade to Node 6 and re-install Angular CLI. With Node Version Manager maintaining and upgrading multiple version of Node is as simple as:

    nvm install 6
    nvm use 6
    

    Angular CLI now installs and runs:

    npm install -g angular-cli@latest
    ng --version
      angular-cli: 1.0.0-beta.16
      node: 6.6.0
      os: linux x64
    ng foo
    cd foo
    ng serve
    

    Note 1: The install failure says npm WARN engine angular-cli@1.0.0-beta.16: wanted: {"node":">= 4.1.0"} but Node 4.6 fails similarly for me; so, use Node 6, instead. Node 5 work but there are disconcerting warnings during the install; see Note 2 below.

    Successful Node 6 install:
