Question

〜我正在为android创建一个新应用，当我命令 react-native run-android 时，出现此错误：错误：捆绑失败：错误：无法解析fs中的模块C:\Users\luis.arnoni.fritzen\Documents\ReactNative\Hello\node_modules\expo-cli\build\exp.js：急速模块映射中不存在模块fs

阅读一些文档，这似乎是fs软件包的问题。我尝试安装fs-extra软件包，但出现错误

react-native没有完整的节点环境。并非所有节点模块都可与react-native一起使用。您可以考虑使用https://github.com/itinance/react-native-fs
