Desired functionality.

There should'nt be any warnings about incorrect peer dependencies.

Mention any other details that might be useful.

$ npm list webpack
angular-cli-new140@0.0.0 C:\Users\N2632888\dev\test\angular-cli-new140
`-- @angular/cli@1.4.0-rc.1

Similar problem: couldn't start the dev server because of:

Cannot find module 'webpack/lib/node/NodeTemplatePlugin'
Error: Cannot find module 'webpack/lib/node/NodeTemplatePlugin'

And saw this while installing:

Is yarn configured as the CLI's package manager? It looks like the package manager is erroneously nesting webpack under the CLI dependency.

It looks like a bug in Yarn 1.0.1 release. See yarnpkg/yarn#4342.
