React-Native Packager Failure: Duplicate module name : <p>This happened seemingly randomly during development. When trying to run <code>npm start</code> or <code>react-native run-ios</code>, I get the following error:</p>

<pre><code>Failed to build DependencyGraph: @providesModule naming collision:
  Duplicate module name: react-native-vector-icons
  Paths: /Users/chandlervdw/Repos/Relay/mobile/node_modules/react-native/local-cli/rnpm/core/test/fixtures/files/package.json collides with /Users/chandlervdw/Repos/Relay/mobile/node_modules/react-native/Libraries/Animated/release/package.json

This error is caused by a @providesModule declaration with the same name accross two different files.

</code></pre>

<p>Strangely, <code>/Users/chandlervdw/Repos/Relay/mobile/node_modules/react-native/local-cli/rnpm/core/test/fixtures/files/package.json</code> actually does list <code>react-native-vector-icons</code> as the name for the module???</p>

<p>If I delete that file, the error no longer happens but the packager gets stuck at 93% and complains about a completely irrelevent library not being found.</p>

<p>I blew away my repo and even reinstalled everything, including <code>npm</code>, <code>rnpm</code>, and even upgrading <code>node</code>. I'm running the same versions of everything as my teammates, who are able to run the packager without issues.</p>
