开始入坑RN,从最开始的学起不免有很多乱七八糟的问题,记录在这里。node
按照官网教程搭建开发环境并按照下面代码运行时候有报错,显示8081端口的问题react
react-native init AwesomeProject cd AwesomeProject react-native run-ios
应该就是端口占用的问题,首先找到占用程序,用下面代码,加上sudo,若是什么都没有发生。能够看到PID。ios
lsof -i :8081
而后用下面命令杀掉,也加上sudo。git
kill -9 <PID>
参考连接github
继续运行又显示报错:npm
ERROR ENOENT: no such file or directory, lstat '/AwesomeProject/ios/build/ModuleCache/3F1D94PC0NUP2/AVFoundation-1M2ASOEW37WIZ.pcm-53d428b3'
{"errno":-2,"code":"ENOENT","syscall":"lstat","path":"/AwesomeProject/...json
在github找到解决方案,在工程中找到RCTWebSocket,移除build setting中custom compiler flags。以下图:
react-native
参考连接缓存
npm WARN react-native@0.35.0 requires a peer of react@~15.3.1 but none was installed.
Unable to resolve module react/lib/ReactUpdates ...... Module does not exist in the module map or in theseapp
由于package.json依赖中react是^15.3.1,致使了版本不匹配的问题,因此改成~15.3.1,删除node_modules,从新npm install,最后npm start -- --reset-cache,清理一下缓存。这样再运行app便可顺利进行。
