title: Couldn't find preset "env" relative to directory
body: <p>So far I have been unsuccessful in an attempt to use the <code>env</code> preset. I browsed the git issues that others have raised such as <a href="https://github.com/babel/babel-preset-env/issues/186" rel="noreferrer">this</a>, and implemented some of the suggestions that appeared to work for others, but no luck so far.</p>
  
  <p>Here's what I'm working with:</p>
  
  <p>package.json</p>
  
  <pre><code>"bundle": "browserify ./client/app.js -d -o ./public/o.js -t [ babelify --presets [ env ] ]",
  "devDependencies": {
    "@babel/cli": "^7.0.0-beta.40",
    "@babel/preset-env": "^7.0.0-beta.40",
    "babel-core": "^6.26.0",
    "babelify": "^8.0.0"
  ...
  </code></pre>
  
  <p>And here is the error:</p>
  
  <pre><code>Error: Couldn't find preset "env" relative to directory "/Users/user/Documents/git/ts/client" while parsing file: /Users/user/Documents/git/ts/client/app.js
  </code></pre>
  
  <p>Anything I could be missing?</p>
