title: Ionic Pro App fails to build on Ionic's build service due to an issue with a package
body: <p>I am using the <a href="https://www.npmjs.com/package/jsonpath" rel="nofollow noreferrer">jsonpath</a> package from NPM on my Ionic 3.0 app. It is in my package.json like so:</p>
  <pre><code>&gt; &quot;jsonpath&quot;: &quot;1.0.0&quot;,
  </code></pre>
  <p>On my local machine, the app builds successfully and all is well.</p>
  <p>However, once I push the code off to Ionic's servers, the code fails to transpile because of the following error:</p>
  <blockquote>
  <p>Cannot find module 'JSONPath'</p>
  </blockquote>
  <p>I noticed that earlier in the build log npminstall appears to successfully install this dependency:</p>
  <blockquote>
  <p>jsonpath@1.0.0 postinstall /usr/src/app/node_modules/jsonpath</p>
  <p>...</p>
  <p>npm install succeeded</p>
  </blockquote>
  <p>So unfortunately there is little clue what the problem might be.</p>
  <p>Here's how I am referencing this dependency in my TypeScript:</p>
  <pre><code>import { JsonPath } from 'JSONPath';
  </code></pre>
  <p>Am I doing something silly anywhere? Any suspicions as to why this might be happening?</p>
