运行CleanMyMac后React Native Expo Go在Android模拟器崩溃求助

问题描述 #

运行CleanMyMac清理Mac后，React Native Expo Go项目无法在Android模拟器启动，iOS模拟器正常。已尝试清理缓存、重装Node/npm/watchman/expo-cli、更新SDK和APK等操作，问题仍存在。启动Expo Go时logcat报错如下：

解决方案 #

1. 修复Android NDK依赖 #

libc++_shared.so来自NDK，CleanMyMac可能误删或损坏了NDK文件：

• 打开Android Studio，进入Settings -> Appearance & Behavior -> System Settings -> Android SDK -> SDK Tools
• 勾选NDK (Side by side)，点击"Show Package Details"，选择Expo SDK对应的NDK版本（如Expo 50对应NDK 25.2.9519653），重新安装覆盖
• 确认NDK路径已配置到环境变量：export ANDROID_NDK_HOME=/Users/[你的用户名]/Library/Android/sdk/ndk/[对应版本号]

2. 重置/重建Android模拟器 #

• 打开Android Studio的Device Manager，选中当前模拟器，点击... -> Wipe Data清除数据
• 若无效，删除模拟器，新建arm64-v8a架构的系统镜像（适配M4原生arm64，避免x86转译兼容性问题）

3. 调整Expo项目Android配置 #

在项目根目录android/app/build.gradle中添加以下配置，确保libc++_shared.so被正确打包：

android {
    defaultConfig {
        ndk {
            abiFilters 'arm64-v8a'
        }
    }
    packagingOptions {
        pickFirst 'lib/arm64-v8a/libc++_shared.so'
    }
}

执行npx expo prebuild --clean重新生成原生文件

4. 彻底清除深层缓存 #

# 清除Expo缓存
npx expo r -c
# 清除npm缓存
npm cache clean --force
# 清除watchman缓存
watchman watch-del-all
# 删除依赖文件并重装
rm -rf node_modules package-lock.json yarn.lock
npm install

5. 恢复CleanMyMac误删文件 #

打开CleanMyMac，进入Cleanup -> Logs，查看最近清理记录，恢复被误删的Android SDK/NDK相关文件
