0 环境搭建

根据http://reactnative.cn/docs/0.41/getting-started.html#content

1. 安装Chocolatey, cmd输入

    @powershell -NoProfile -ExecutionPolicy Bypass -Command "iex ((new-object net.webclient).DownloadString('https://chocolatey.org/install.ps1'))" && SET PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin

2. 安装Python2(不支持3), 使用Chocolatey安装, cmd输入

    choco install python2

3. 安装Node(避开Node7.0以上版本,手动下载), 使用Chocolatey安装, cmd输入,

choco install nodejs.install

建议手动下载安装低版本node

• 须加设npm镜像以加速后面的过程, 勿用cnpm(cnpm安装的模块路径奇怪,packager无法识别)

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

  • 如果报错"npm不是内部或外部命令",cmd运行(可能需要进node的安装目录)http://www.geekqanda.com/index.php/14267/%E5%9C%A8cmd%E4%B8%AD%E8%BE%93%E5%85%A5npm-install-g-express%EF%BC%8C%E6%98%BE%E7%A4%BAnpm%E4%B8%8D%E6%98%AF%E5%86%85%E9%83%A8%E6%88%96%E5%A4%96%E9%83%A8%E5%91%BD%E4%BB%A4?show=14295

      npm install -g express-generator
    

4. 安装yarn(facebook替代npm的工具, 加速node模块下载), 以及ReactNative的命令行工具react-native-cli

npm install -g yarn react-native-cli

5. 安装git,Android Studio和JDK

choco install jdk8
choco install git

• jdk1.8及以上

• Android Studio

  • 需2.0以上,安装选项尽量别动

  • 需选择Android SDK和Android Device Emulator, Android Support Repository

  • Custom模式安装

    
    
    

  • 安装组件需有模拟器和HAXM加速

    
    
    

  • 初次进入时选择Configure | SDK Manager,
    

    

  • 在SDK Platforms窗口中，选择Show Package Details，然后在Android 6.0 (Marshmallow)中勾选Google APIs、Android SDK Platform 23、Intel x86 Atom System Image、Intel x86 Atom_64 System Image以及Google APIs Intel x86 Atom_64 System Image。
    

    

  • 在SDK Tools窗口中，选择Show Package Details，然后在Android SDK Build Tools中勾选Android SDK Build-Tools 23.0.1（必须是这个版本）。
    

    

  • 然后还要勾选最底部的Android Support Repository.

    
    
    

6. 配置sdk路径为ANDROID_HOME的环境变量

• 命令行窗口需要全部关掉重开才可应用

7. 测试安装

react-native init AwesomeProject
cd AwesomeProject
react-native run-android

问题1 报错"Command yarn add react-native --exact failed."

• 解决方法
  • 安装7.0以下node.js

问题2 adb devices找不到genymotion

• 解决方法
  • 将setting里的adb路径改成自带sdk的路径,而不是default

问题3 Could not install the app on the device, read the error above for details.

Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:https://facebook.github.io/react-native/docs/android-setup.html

• 解决方法
  • 检查下Android_Home的路径

问题4 小米关闭"通过usb验证应用程序"

• 解决方法
  • 本身是无法选择的,安装google框架后即可

问题4 Failed to establish session

• 小米系统的MIUI优化功能会在代码安装apk时弹出一个提示框,然而RN会自动打包安装到手机,这个 "自动安装" 的过程不会唤醒提示框,所以默认拒绝.
• 解决方法
  • 进入开发者模式,关闭MIUI优化,自动重启后即可

    https://github.com/facebook/React-native/issues/6499

问题5 安装后白屏

• 解决方法
  • 权限里开启"悬浮窗权限"即可

问题6 安装后红屏

• 解决方法
  • 摇一摇手机,弹出悬浮窗,点击Dev Settings 然后点击 Debug server host & port for devices
  • 输入电脑ip(cmd->ipconfig -> 本地连接的ipv4地址,或者打开网络和共享中心 -> 本地连接 -> 详细信息 -> ipv4地址)+固定端口号8081,即格式为xxx.xxx.xxx.xxx:8081
  • 回到空白界面, 再次摇一摇手机, 选择Reload,出现Welcome to React Native!

问题7 模拟器

• 如果使用Genymotion需要setting -> ADB -> use customAndroid SDK tools,选择本地的sdk
• 

问题8 未解决红米note2的安装问题

• 状况:
  • 只在红米note2上出现,系统是muui8.0,android 5.0.2
  • 同款5.0.2moto手机没问题
  • 6.0的米和7.0的华为没问题
  • 已关闭了miui优化
• 尝试解决:
  • Unknown failure ([CDS]close[0]) 可能是gradlle版本过高,build.gradle改为1.2.3, gradle.wrapper改为2.2-all,无效,目前已7.0,此方法未解决
