刚开始上手RN,碰到很多坑,记录一下。碰到问题多去看看github上面的issue!
启动命令react-native run-ios报错
1、:xcrun: error: unable to find utility "instruments", not a developer tool or in PATH
解决方案
sudo xcode-select -s /Applications/Xcode.app/Contents/Developer/
重新跑一下就好了
2、bundling failed: Error: Unable to resolve module './../react-transform-hmr/lib/index.js'
解决方案
react-native start --reset-cache
3、Cannot read property 'bindings' of null
node_modules/react-native/Libraries/react-native/react-native-implementation.js: Cannot read property 'bindings' of null (null))
这个大致是babel包的版本问题,解决方案
npm install babel-preset-react-native@5 --save
4、_this._registerEvents is not a function. xxx
这个报错具体原因不明,但是react-native的npm版本从0.57降到0.56之后就好了。。。就好了。。。莫名其妙的好了。。。
持续踩坑,持续更新
