linux平台安装React Native遇到的坑

3年前我在windows平台安装过React Native,我一直都记忆犹新,那个时候facebook刚推出支持安卓,然后花了一天的时间在自己的window电脑上配置好了,还是很兴奋的,安装博客地址如下

Android之Windows下搭建React Native Android开发环境（差不多搞了一天）

现在我的开发环境是ubuntu,所以需要在这个平台安装react native,遇到的坑如下

问题   1

ERROR  Metro Bundler can't listen on port 8081

解决办法

因为有地方占用了8081端口,所以找到这个端口的进程pid,然后kill就行

sudo lsof -i :8081
kill pid

问题 2

A problem occurred configuring project ':app'.
> SDK location not found. Define location with sdk.dir in the local.properties file or with an ANDROID_HOME environment variable.

解决办法

这个在我们react native init program里面我们项目里面的android文件夹里面少了local.properties文件,在之前的项目目录下,把这个文件拷贝到这个目录就行了

最后编译好的部分显示如下

../react-native run-android
