需要适当的加载器来处理此文件类型 | * @type {import‘../../ ipfs / src / core / components / add-all’AddAll <import‘’HttpOptions>}

问题描述

我从GitHub下载了源代码并尝试运行它。 它运行了，但是出现了“ ipfs-api”问题，因此我安装了最新版本的“ iphs-http-client”，现在它弹出了很多与之相关的错误

如果告诉我原因也可以解决，请告诉我，我是新来的

error  in ./node_modules/ipfs-http-client/src/add-all.js

You may need an appropriate loader to handle this file type.

解决方法

您似乎正在通过webpack使用babel来转译源代码，并且无法解析异步生成器函数语法。您可能需要添加插件或以其他方式修复您的配置。
