Quickly create ReactNative project

1. After installing node recommend setting npm mirror to accelerate the process behind (or scientific use Internet tools). Note: Do not use cnpm! cnpm installed modules rather strange path, packager does not recognize normal! (Rn command-line tool does not recommend using npm and cnpm)

   npm config set registry https://registry.npm.taobao.org --global

   npm config set disturl https://npm.taobao.org/dist --global

2. Yarn and React Native command-line tool (react-native-cli) (rn command-line tool recommended Yarn)

   • Yarn is an alternative npm tools provided by Facebook, you can speed up the download node module.

   • React Native command-line tool used to create, initialize, update project, run the Package Service (packager) and other tasks.

   npm install -g react-native-cli

   • Similarly also provided after the installation of the mirror source yarn:

   yarn config set registry https://registry.npm.taobao.org --global

   yarn config set disturl https://npm.taobao.org/dist --global

3. Run react-native init myProjectcreate React-Native Project

4. Run cd myProjectswitch to the project root directory, run adb devicesto ensure that the device is connected to the computer

5. Run react-native run-androidpacked Android project compiled and deployed to the emulator or development machine

6. Before running a command, to ensure that the device is connected to a computer, you can run adb devicesto view a list of devices currently accessed; if not checked device list, make sure the phone is turned on 开发者模式, while the driver to install the phone on your computer;

7. Note: The first package when the network will download gradlea file related to the need to wait for a long time, you can directly from http://www.androiddevtools.cn/manually download the corresponding version of the gradlefile, unzip and manually copy to C:\Users\自己的用户名\.gradle\wrapper\diststhe directory;

8. Note: Next, if it is the first time packaged, from https://jcenter.bintray.comdownloading a lot of dependencies, this time need to be patient, if the middle there has been a long time Caton, we need to Ctrl+Cstop the package, and re-runreact-native run-android
