Hi,

The latest update to this package causes importing to fail.

npm install mobx-react
echo "require('mobx-react')" > test.js
node test.js

Error: Cannot find module '/.../node_modules/mobx-react/dist/mobxreact.js'. Please verify that 
    the package.json has a valid "main" entry

  path: '/.../node_modules/mobx-react/package.json',
  requestPath: 'mobx-react'

Seems the file main points to is not present anymore
