RN Exception: iOS undefined is n

异常

undefined is not an object ("evaluating _react3.default.PropTypes.shape")

解决方法

如果已经安装react-native-deprecated-custom-components，那么卸载它。

npm uninstall --save react-native-deprecated-custom-components

再安装react-native-custom-components,

npm install --save https://github.com/facebookarchive/react-native-custom-components.git
// 或
npm install --save react-native-custom-components

安装完成后，记得将package-lock.json中一定要不包含react-native-deprecated-custom-components。
