1.Cannot read property 'throwIfClosureRequired' of undefined (While processing preset: "/Users/poet/Documents/rn_project/DouBan/node_modules/babel-preset-react-native/index.js")
解決辦法：
If not work try this solution.
i) delete node_module folder.
ii) Open your package.json and change the devDependencies to:
"devDependencies":
{ ...
"babel-preset-react-native": "4.0.0",
... },
Then run npm install. It's worked for me.
2.如何添加導航控制器
yarn add react-navigation //添加導航控制器 yarn add react-native-vector-icons //添加iconFont,將這個Module下的Font的文件夾中的字體復制到Xcode的項目中去，並添加到Resource中，才會有效。

3.Module `react-navigation` does not exist in the Haste module map or in these directories（導航控制器已經添加過了，但是還報這個錯）
解決辦法：
先卸載這個模塊： npm uninstall react-navigation
然后重新安裝： yarn add react-navigation

4.（添加自定義字體）Getting Started with NativeBase
a.瀏覽到node_modules/react-native-vector-icons目錄，然后選中 Fonts 目錄，將Fonts目錄中的所有文件拷貝到工程文件目錄下，然后將Fonts目錄拖到工程文件中，記得勾選Create Groups復選框。
b.編輯Info.plist文件，添加自定義字體的名稱。

5. 添加Native Base
//首先在項目根目錄下執行 npm install native-base --save //由於native base依賴react-native-vector-icons,所以需要安裝react-native-vector-icons npm install react-native-vector-icons --save
//添加依賴react-native-vector-icons到原生工程 react-native link react-native-vector-icons
