關於react-native引入第三方庫，運行react-native link xxxxx後項目沒法運行

最新版本的react-native中，官方表示將要移除

AsyncStorage，推薦使用@react-native-community/async-storage，好吧官方常常這麼幹

 

按照官方提示

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

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

好吧，果真不負衆望的報錯了

解決方案

1.清除yarn緩存 yarn cache clean
2.清除npm緩存 npm cache clean -f
3.在項目文件夾中有一個package.json 文件，裏面記錄了該項目全部安裝的依賴環境，若項目文件出現依賴環境報錯的狀況，則能夠刪除依賴node_module文件夾，在從新yarn install 一次 ， 從新安裝依賴。
4.對於項目出現出現.../.../debug/.../../文件夾報錯，多是緩存致使的問題，進入android文件夾下，輸入命令 ./gradlew clean 命令清除緩存，也可以使用android studio 中的菜單按鈕的build下的clean project清除環境，在使用rebuild project 從新跑一次項目。
