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-x64
export 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 -v
v4.4.4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/HelloWorld
Installing 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 80811 如果遇到这个错误说明有个服务已经在运行了,先关闭它

echo 256 | sudo tee -a /proc/sys/fs/inotify/max_user_instances
echo 32768 | sudo tee -a /proc/sys/fs/inotify/max_queued_events
echo 65536 | sudo tee -a /proc/sys/fs/inotify/max_user_watches
watchman 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-android
JS server already running.

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 FAILED3.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 (
container}>
Hello world
);
}
}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.
