将 fineuploader 与 react-rails 结合使用

Question

我正在尝试将 fineuploader 与 react 一起使用，并且已经安装了所有相关的依赖项。以下是我使用的代码：-

import React, { Component } from 'react'

import FineUploaderTraditional from 'fine-uploader-wrappers'
import Gallery from 'react-fine-uploader'

import 'react-fine-uploader/gallery/gallery.css'

const uploader = new FineUploaderTraditional({
    options: {
        chunking: {
            enabled: true
        },
        deleteFile: {
            enabled: true,
            endpoint: '/uploads'
        },
        request: {
            endpoint: '/uploads'
        },
        retry: {
            enableAuto: true
        }
    }
})

class UploadComponent extends Component {
    render() {
        return (
            <Gallery uploader={uploader} />
        )
    }
}

export default UploadComponent

但是我得到以下错误：-

Uncaught Error: Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in. Check the render method of `Gallery`.

我一直在关注 React fineuploader 文档，我尝试了一些不同的方法，但似乎没有任何效果。

Answer 1

我认为您必须从模块中导入 Gallery 组件。

import Gallery from 'react-fine-uploader'

更新：
也可以尝试将 Gallery 包裹在 div

中

class UploadComponent extends Component {
    render() {
        return (
          <div>
            <Gallery uploader={uploader} />
          </div>
        )
    }
}

Answer 2

问题是一些未满足的依赖关系，在我的例子中是：

react-transition-group@1.x

我有

react-transition-group@2.x

删除 2.x 并安装 1.2.1 解决了问题。

密切关注您尝试配置的任何软件包的安装依赖项。
