title: 'ENV' is not recognized as an internal or external command
body: <p>So, I have been following tutorials of Eat The Blocks on ToDo List Ethereum DApp. Done till step 6, but while running the command <code>npm run dev-front</code> I am getting this error.</p>
  
  <pre><code>&gt; Project@1.0.0 dev-front L:\Project
  &gt; ENV=development node_modules/.bin/webpack --watch
  
  'ENV' is not recognized as an internal or external command,
  operable program or batch file.
  npm ERR! code ELIFECYCLE
  npm ERR! errno 1
  npm ERR! Project@1.0.0 dev-front: `ENV=development node_modules/.bin/webpack --watch`
  npm ERR! Exit status 1
  npm ERR!
  npm ERR! Failed at the Project@1.0.0 dev-front script.
  npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

  <p>This is the link to the tutorial <a href="https://eattheblocks.com/todo-list-ethereum-dapp-step6/" rel="noreferrer">https://eattheblocks.com/todo-list-ethereum-dapp-step6/</a>
  I am developing on Windows 10.</p>
  
  <p>So I looked in some of the forums, it said to set environment variable path is different in Windows 10.</p>
  
  <pre><code>"scripts": {
      "dev-front": "ENV=development node_modules/.bin/webpack --watch",
      "dev-back": "nodemon server.js",
      "start": "node server.js",
      "test": "echo \"Error: no test specified\" &amp;&amp; exit 1"
    },
  </code></pre>
  
  <p>This is the code. How do we set the environment path?
  It would be nice if anyone helps me with this. Thank you in advance.</p>
