Question

我将react-native从0.48.4升级到0.51.0之后我得到了这个错误。每当我运行packager.Here是控制台输出

bundling failed: TypeError: /node_modules/react-native/Libraries/Animated/src/createAnimatedComponent.js: Duplicate declaration "AnimatedComponent" (This is an error on an internal node. Probably an internal error)

信息：当我工作时react-native 48.4如果我启用Hot模块重新加载（hmr）我曾经得到这个错误。更新到51.0之后由于捆绑错误我无法开发服务器

可能问题在于transform-react-remove-prop-types babel插件。

尝试从.babelrc删除此插件，它将解决问题。

重复声明“AnimatedComponent”可能是react-native中的内部错误
