通过react-native run-android运行React-Native项目后，我遇到错误。即使Android Studio在同步时未显示任何错误。
错误：
* What went wrong:
Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForDebug'.
> com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex

/**
* The react.gradle file registers a task for each build variant (e.g. bundleDebugJsAndAssets

* cycle. By default, bundleDebugJsAndAssets is skipped, as in debug/dev mode we prefer to load the
* bundle directly from the development server. Below you can see all the possible configurations
* and their defaults. If you decide to add a configuration block, make sure to add it before the
* `apply from: "../../node_modules/react-native/react.gradle"` line.

在我实施react-native-navigation（通过wix）之后，该项目运行良好，此错误开始出现。
到目前为止我尝试过的事情：
1.delete .gradle文件夹并再次重建项目
