Ubuntu React Native 环境搭建

Ubuntu React Native 环境搭建

本人环境是Ubuntu 64位 14.0.4 .

安装 node.js

过程:

• 1.到node官网下载https://nodejs.org/en/
• 2.将node-v4.4.4-linux-x64.tar.xz 下载到的 文件解压到自己的目录.
• 3.将node配置成环境变量如下

export NODE_HOME=/home/djh/djh/node-v4.4.4-linux-x64export PATH=$NODE_HOME/bin:$PATH

在终端输入 node -v 如下出现版本号则说明安装成功

djh@djh-All-Series:~$ node -vv4.4.4

问题:

这个步骤简单 暂时没有出现任何问题.

安装 watchman

过程:

安装依赖

$ sudo apt-get install autoconf  automake python-dev

安装 watchman, 如果出错, 查看安装依赖的详细文档

$ git clone https://github.com/facebook/watchman.git$ cd watchman$ git checkout v4.3.0  # the latest stable release$ ./autogen.sh$ ./configure$ make$ sudo make install

问题:

这个步骤简单 暂时没有出现任何问题.如果有问题可以参考文档

安装 react-native

过程:

$ npm install -g react-native-cli

问题:

这个步骤简单 暂时没有出现任何问题.

创建helloworld项目

过程:

$ react-native init HelloWorld

问题:

This will walk you through creating a new React Native project in /home/djh/ReactNativeProject/HelloWorldInstalling react-native package from npm...

这个创建需要点时间,耐心等待.

运行helloworld

过程:

djh@djh-All-Series:~/ReactNativeProject$ cd HelloWorld/djh@djh-All-Series:~/ReactNativeProject/HelloWorld$  react-native start

问题:

ERROR  Packager can't listen on port 8081

1 如果遇到这个错误说明有个服务已经在运行了,先关闭它

2.如果遇到这个问题 解决如下 在终端输入:

echo 256 | sudo tee -a /proc/sys/fs/inotify/max_user_instancesecho 32768 | sudo tee -a /proc/sys/fs/inotify/max_queued_eventsecho 65536 | sudo tee -a /proc/sys/fs/inotify/max_user_watcheswatchman shutdown-server

官网说这个是watchman的什么个数限制什么的,具体参考 ++https://facebook.github.io/watchman/docs/install.html#system-specific-preparation++

3.因为是第一次弄傻傻的 什么都不懂就在这里一直等,其实服务起来后,就要新开个终端.在这个目录就可以运行到机器了. 这边用的是虚拟机Genymotion

运行apk到android设备

过程:

djh@djh-All-Series:~/ReactNativeProject/HelloWorld$  react-native run-androidJS server already running.Building and installing the app on the device (cd android && ./gradlew installDebug...:app:preBuild UP-TO-DATE:app:preDebugBuild UP-TO-DATE:app:checkDebugManifest:app:preReleaseBuild UP-TO-DATE:app:prepareComAndroidSupportAppcompatV72301Library:app:prepareComAndroidSupportRecyclerviewV72301Library:app:prepareComAndroidSupportSupportV42301Library:app:prepareComFacebookFrescoDrawee081Library:app:prepareComFacebookFrescoFbcore081Library:app:prepareComFacebookFrescoFresco081Library:app:prepareComFacebookFrescoImagepipeline081Library:app:prepareComFacebookFrescoImagepipelineOkhttp081Library:app:prepareComFacebookReactReactNative0260Library:app:prepareOrgWebkitAndroidJscR174650Library:app:prepareDebugDependencies:app:compileDebugAidl:app:compileDebugRenderscript:app:generateDebugBuildConfig:app:generateDebugAssets UP-TO-DATE:app:mergeDebugAssets:app:generateDebugResValues:app:generateDebugResources:app:mergeDebugResources:app:bundleDebugJsAndAssets SKIPPED:app:processDebugManifest:app:processDebugResources

问题:

1.最好先配置好android 的环境和build tool 这里一般需要23.0.1的
++export ANDROID_HOME=/home/djh/djh/adt-bundle-linux-x86_64-20140702/sdk++
如果没有的话使用sdk Manager 下载好.不然会出现很多资源找不到的我问题.

2.第一次运行时间会比较久.

* What went wrong:Execution failed for task ':app:installDebug'.> com.android.builder.testing.api.DeviceException: No connected devices!* Try:Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.BUILD FAILED

3.遇到上面问题说明没有打开设备,将Genymotion打开.就可以了.

修改程序将文字修改成Helloworld

过程

1将工程目录下的 index.android.js 下面一段改改

class HelloWorld extends Component {  render() {    return (      <View style={styles.container}>          <Text style={styles.reply}>         Hello world        </Text>      </View>    );  }}

问题:

直接按住设备的菜单键 ,选择Reload js 就重新加载了.然后就变成下面的了

后续

将学习运行在真是的手机设备中.
