关于react-native引入第三方库，运行react-native link xxxxx后项目无法运行

最新版本的react-native中，官方表示将要移除

AsyncStorage，推荐使用@react-native-community/async-storage，好吧官方经常这么干

 

按照官方提示

yarn add @react-native-community/async-storage

react-native link @react-native-community/async-storage

好吧，果然不负众望的报错了

错误信息如下

解决方案

1.清除yarn缓存 yarn cache clean
2.清除npm缓存 npm cache clean -f
3.在项目文件夹中有一个package.json 文件，里面记录了该项目所有安装的依赖环境，若项目文件出现依赖环境报错的情况，则可以删除依赖node_module文件夹，在重新yarn install 一次 ， 重新安装依赖。
4.对于项目出现出现.../.../debug/.../../文件夹报错，可能是缓存导致的问题，进入android文件夹下，输入命令 ./gradlew clean 命令清除缓存，也可使用android studio 中的菜单按钮的build下的clean project清除环境，在使用rebuild project 重新跑一次项目。
