React Native 基础报错及解决方案记录

Posted 2021-01-11 heioray

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 [email protected] --save

持续踩坑，持续更新
