title: Webpack: After installing webpack and webpack-cli still getting error when running webpack
body: <p>I have the latest versions of webpack installed:</p>
  
  <pre><code>"webpack": "^4.0.0",
  "webpack-cli": "^2.0.9"
  </code></pre>
  
  <p>Yet when I run <code>webpack</code> in the terminal I get the following:</p>
  
  <pre><code>The CLI moved into a separate package: webpack-cli.
  Please install 'webpack-cli' in addition to webpack itself to use the CLI.
  -&gt; When using npm: npm install webpack-cli -D
  -&gt; When using yarn: yarn add webpack-cli -D
  </code></pre>
