React Native：错误找不到符号 com.swmansion.gesturehandler.react.RNGestureHandlerPackage

Question

我知道很多相关问题已经问过，但仍然没有一个有效。

错误：

我有什么：

在 android\settings.gradle

include ':react-native....

这两个已经在那里了

在

 MainAplication.java

import  com.swmansion.gesturehandler.react.RNGestureHandlerPackage;

已经在那里 并且

new RNGestureHandlerPackage() List

不存在，所以我添加了。

rm -rf node_modules
npm cache clean --force
./gradlew clean

然后全部重新安装。

================更新================

我通过 React 降级到

"react-native-gesture-handler": "~2.1.3"

来修复它 和静态缓存。 T

Answer 1

在新版本（RNGH 2）中你必须删除

.react

，所以它只是

import com.swmansion.gesturehandler.RNGestureHandlerPackage;

！

Answer 2

确保添加了

react-native-reanimated

插件到 babel.config.js

module.exports = {
  presets: ['module:metro-react-native-babel-preset'],
  plugins: ['react-native-reanimated/plugin'],
};

Answer 3

删除node_modules文件夹

删除package-lock.json

npm i

or

npm i --legacy-peer-deps

cd android
./gradlew clean
