在学习React Native的过程中，相信对于一个App开发工程师，没有充分的学习过前端开发技术的同学来说，顺利的搭建好开发环境还是比较纠结的。
下面，我就根据我自己学习过程中的总结，跟大家讲解讲解如何从零开始顺利的搭建React Native的开发环境，希望对大家的学习有所帮助。我是以Ubuntu操作系统进行开发的，具体步骤如下：
1.安装Git
apt-get install git
2.安装JDK
a.在官方网站下载相关的jdk-8u77-linux-x64.tar.gz包；
b.在你的指定目录下解压；
tar zxvf jdk-8u77-linux-x64.tar.gz
c.JAVA_HOME环境变量的配置；
编辑profile文件：
gedit /etc/profile
export JAVA_HOME=/usr/local/opt/jdk1.8.0_77
export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib:$CLASSPATH
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH
使用配置生效：
source /etc/profile
d.检验安装是否成功：java -version；
3.安装Android Studio和Android SDK
a.将下载的android-studio-ide-141.2456560-linux.zip解压到指定目录下（/usr/local/opt）下
unzip android-studio-ide-141.2456560-linux.zip
b.将下载的android-sdk_r24.4.1-linux.tgz解压到指定目录（/usr/local/opt）下
tar zxvf android-sdk_r24.4.1-linux.tgz
c.启动android-studio
d.创建demo应用程序并运行，检测环境是否安装成功；
ERROR: Cannot start Android Studio
No JDK found. Please validate either STUdio_JDK,JDK_HOME or JAVA_HOME environment variable points to valid JDK installation.
处理1：避免使用sudo方式启动；
sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0 lib32stdc++6
提示3：如果在启动模拟器的时候，有如下报错，则处理如下：
Starting emulator for AVD 'AVD_for_Galaxy_Nexus_by_Google'
PANIC: Could not find AVD_for_Galaxy_Nexus_by_Google.ini file in $ANDROID_AVD_HOME nor in $HOME/.android/avd"!
处理3：ln -s /root/.android/avd /home/pengchengxiang/.android/avd
System Health
IBus prior to 1.5.11 may cause input problem. See IDEA-78860 for details.
处理4：System Settings > Language Support，改为Keyboard input methodat the bottom of the page fromibustonone.
the path ''/usr/local/opt/android-sdk-linux' is not writeable,please chose a new location
处理5：
chown -R root /usr/local/opt/android-sdk-linux
chgrp -R root /usr/local/opt/android-sdk-linux
chmod -R 777 /usr/local/opt/android-sdk-linux
4.定义ANDROID_HOME环境变量
a.在/etc/profile添加如下环境变量：
export ANDROID_HOME=/usr/local/opt/android-sdk-linux
export PATH=$PATH:$ANDROID_HOME/platform-tools
b.source /etc/profile使得配置生效；
5.使用gradle deamon
a.在gradle官网下载gradle-2.12-all.zip
b.将其解压到你安装目录下/usr/local/opt；
unzip gradle-2.12-all.zip
export GRADLE_HOME=/usr/local/opt/gradle-2.12
export PATH=$PATH:$GRADLE_HOME/bin
d.source /etc/profile使得配置生效；
e.执行gradle -v确定安装成功；
f.配置gradle deamon
touch ~/.gradle/gradle.properties && echo "org.gradle.daemon=true" >> ~/.gradle/gradle.properties
6.配置你的SDK
a.打开你的Android SDK Manager，在展示的窗口检查你是否安装如下组件：
export ANDROID_HOME=/usr/local/opt/android-sdk-linux
export PATH=$PATH:$ANDROID_HOME/platform-tools
c.source /etc/profile使得配置生效；
7.安装Genymotion模拟器
a.在Genymotion官网下载安装包genymotion-2.6.0-linux_x64.bin；
b.修改安装包的执行权限，并执行安装指定安装目录；
pengchengxiang@ubuntu:~/Desktop$ chmod +x genymotion-2.6.0-linux_x64.bin
pengchengxiang@ubuntu:~/Desktop$ sudo ./genymotion-2.6.0-linux_x64.bin -d /usr/local/opt/
[sudo] password for pengchengxiang:

- Installing launcher icon ............................. OK
Installation done successfully.
You can now use these tools from [/usr/local/opt/genymotion]:
- genymotion
- genymotion-shell
- gmtool
c.进入到/usr/local/opt/genymotion目录，启动模拟器；
pengchengxiang@ubuntu:/usr/local/opt/genymotion$ ./genymotion
提示1：运行虚拟机的时候，如果弹出对话框报错如下：
Unable to start the virtual device.
VirtualBox cannot start the virtual device.
To find out the cause of the proble.start the virtual device from VirtualBox.
处理1：Configure virtual device->Processor+Base Memory调整为1+1024；
提示2：
运行虚拟机的时候，如果弹出对话框报错如下：
The Virtual device got no Ip address.
The VirtualBox DHCP servers has not assigned an IP address to the virtual device.
To find out the cause of the proble.start the virtual device from VirtualBox.
8.安装NodeJS
sudo apt-get install -y build-essential
curl -sL https://deb.nodesource.com/setup_4.x | sudo -E bash -
sudo apt-get install -y nodejs
9.安装Watchman
git clone https://github.com/facebook/watchman.git
cd watchman
git checkout v4.1.0 # the latest stable release
./autogen.sh
./configure --prefix=/usr/local/opt/watchman
make
sudo make install
