reactjs - Expo React-Native 调试器 - 错误 : Unable to resolve module `./debugger-ui/debuggerWorker.cff11639.js` from ``

Question

我刚刚开始使用 React-Native Expo，其中包含一个在 Android 模拟器中运行 fin 的空白应用程序。但是当我尝试使用 Chrome 开发者工具中的 react-native 调试器时出现错误。

我在 Expo on the emulator 的 Developer 菜单中选择“Debug Remote JS”在 Chrome 中打开这个窗口 /image/V2NKr.png

当我在 chrome 中打开开发人员工具时，我会收到以下错误:

Error: Unable to resolve module `./debugger-ui/ui.bcd3f9d1.js` from ``: 

None of these files exist:

同时在 chrome 控制台中得到这些警告:

DevTools failed to load SourceMap: Could not load content for http://localhost:19001/debugger-ui/ui.bcd3f9d1.js.map: HTTP error: status code 500, net::ERR_HTTP_RESPONSE_CODE_FAILURE

我试过:

• 删除 node_modules 和 package-lock.json 然后 npm install
• Chrome 开发者工具中的清空缓存和硬重新加载
• 清除 Expo 缓存，expo r -c
• 在 Android 虚拟设备上重新安装 Expo

试试这个

npx react-native start --reset-cache
