React Native关于使用CameraRoll出现的问题@react-native-camera-roll/camera-roll@react-native-community/cameraro

坑啊！！！今天使用CameraRoll这个组件需要实现将图片保存到手机的需求，结果使用

yarn react-native run-android

运行的时候一切顺利，但当我开发完这个小需求后要打包的时候，却给我报了类似这个问题：

Error: /react-native-camera-roll/android/build/.transforms/934255b0981cee25c1088e05728c95ca/classes/classes.dex, Type com.reactnativecommunity./react-native-camera-roll.BuildConfig is defined multiple times: /Volumes/DATA/Development/Projects-github/Rejith UW/QubeMeetApp/Qubemeet/node_modules/react-native-webview/android/build/.transforms/934255b0981cee25c1088e05728c95ca/classes/classes.dex, /Volumes/DATA/Development/Projects-github/Rejith UW/QubeMeetApp/Qubemeet/android/app/build/intermediates/external_libs_dex/release/mergeExtDexRelease/classes3.dex

 is defined multiple意味着被定义了多次，刚开始我还百思不得其解，我寻思我这代码在debug模式中运行正常啊，怎么到了release打包就打不了呢。之后我再

yarn react-native run-android

的时候发现大约的确也是报错了；也就是说在我安装完包后最好是要执行上面这句代码，直接yarn start 启动服务的话是不太科学的（可能）。

最后我在react-native-cameraroll/react-native-cameraroll: CameraRoll is a react-native native module that provides access to the local camera roll or photo library. (github)

CameraRoll官网文档上找到了这一句！！！！

Notice: The NPM package name has changed, please change your package.json dependency!

Previous package name: @react-native-community/cameraroll

New package name: @react-native-camera-roll/camera-roll

 真相大白！我去package.js里面找了 果然同时出现了cameraroll和camera-roll两个包名，之后我去掉@react-native-community/cameraroll在运行代码就一切正常了。

记录一下，折腾了我一个小时QAQ
