I've solved this problem.

I think the reason is:
Note: If your react-native version is 0.16+, For now can't support mrn
My RN version is 0.28, so this problem occurred.

The solution is:

1. modify the file \node_modules\mrn.babelrc, delete "whitelist" and its value, add

"plugins": [
    "transform-regenerator",
    "syntax-flow"
    ],
  "presets": [
        "react", "es2015"
  ],

to this file. Finally like this;

.babelrc

{
  "retainLines": true,
  "compact": true,
  "comments": false,
  "sourceMaps": false,
  "plugins": [
    "transform-regenerator",
    "syntax-flow"
    ],
  "presets": [
        "react", "es2015"
  ],
}

1. Modify all the JS file in directory \node_modules\mrn\lib, except config, Icon and Index.

Before:

import React, {
    Component,
    StyleSheet,
    PropTypes,
    View,
    Image
} from 'react-native';

After:

import React, {
    PropTypes,
    Component
} from 'react';
import {
    StyleSheet,
    View,
    Image
} from 'react-native';

In other words, import React and {PropTypes, Component} from 'react', import others from 'react-native'.

Not finished. Delete "export default" before "class ViewName(e.g. Avatar)“. And add "module.exports = ViewName(e.g. Avatar);" to the end of the file.

The core of step 1 is babel, it changed a lot from babel 5 to babel6.
The core of step 2 is RN, if you have a high version RN, some features or syntax changed, so it can not support mrn.

Well, finally I run the project on device successful. But I think my solution is not good, hope someone provide a better one.
