React Native Expo出现"None of these files exist"错误求助

我按照Expo官方TypeScript指南创建项目，执行命令npx create-expo-app -t expo-template-blank-typescript，做完一些基础操作后想恢复到可运行状态，结果失败了。这是我第二次碰到这个没人能解决的错误：

排查与解决步骤 #

• 检查入口配置
  打开app.json或app.config.js，确认entryPoint字段是否被错误设置为./node_modules/expo/AppEntry。正常情况下这个值应该指向项目根目录的App.tsx，也就是"./App.tsx"，改回这个路径即可。

• 清理缓存并重装依赖

  1. 删除项目里的node_modules文件夹和pnpm-lock.yaml锁文件
  2. 执行pnpm install重新安装依赖（如果用npm或yarn，对应换成npm install或yarn install）
  3. 启动项目时清除Metro缓存：npx expo start --clear

• 确认Expo版本一致性
  查看package.json里expo相关包的版本，确保没有版本不兼容的情况。如果版本混乱，直接安装最新版Expo：pnpm add expo@latest

• 检查项目核心文件
  确认项目根目录下存在App.tsx文件，这是模板默认的入口文件。如果被误删，从新创建的空白TypeScript模板中复制一份过来即可。
