您是否完成了错误中的任何建议？因为您只显示了错误而不是触发它的代码，所以答案是菠萝

【解决方案1】：

显然rn-fetch-blob 与expo 不兼容。我之前用 expo 和rn-fetch-blob 处理过这个问题。

“它不适用于 Expo，因为 Expo 不支持本地模块链接。就像你说的，你必须从 Expo 中分离才能运行 react-native link react-native-fetch-blob让它工作。”

https://docs.expo.io/versions/latest/guides/detach.html

您需要使用 XCode 才能使其正常工作。

有几个线程在讨论。不过，世博会没有解决方案。
