react-native - 安装 fs-extra 时失败 - react-native

问题描述

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

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

解决方案

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