title: webpack -v endlessly states that one CLI for webpack must be installed
body: <p>I have npm version 5.60 installed.</p>
  
  <p>In my package.json I have the following two devDependencies:</p>
  
  <pre><code>"webpack": "~1.12.15",
  "webpack-cli": "^3.0.2"
  </code></pre>
  
  <p>Whenever I enter either <code>webpack</code> or <code>webpack -v</code> in the command line, I always receive the same response:</p>
  
  <pre><code>One CLI for webpack must be installed. These are recommended choices, delivered as separate packages:
  - webpack-cli (https://github.com/webpack/webpack-cli)
     The original webpack full-featured CLI.
   - webpack-command (https://github.com/webpack-contrib/webpack-command)
     A lightweight, opinionated webpack CLI.
  We will use "npm" to install the CLI via "npm install -D".
  Which one do you like to install (webpack-cli/webpack-command):
  </code></pre>
  
  <p>I have entered <code>webpack-cli</code> here and I have also installed it via <code>npm install --save-dev webpack-cli</code></p>
  
  <p>I have also tried adding the webpack task runner to visual studio. My solution already has an existing webpack.config.js file. When I select it, I get the blue icon indicating that it utilizes the webpack task runner, but nothing ever appears within the task runner. I think this is just a symptom of webpack not being properly installed, however.</p>
  
  <p>I am using VS 2017 in Windows 10 64.</p>
  
  <p>Any help appreciated.</p>
