javascript - typescript 模块没有导出成员 - react

Question

我正在开发一个 React、redux Typescript 应用程序。我有一种奇怪的情况，在进行一些更改后，其中一个模块已停止导出其成员。

文件夹结构是:

src
|---- components
|---- containers

“组件”文件夹包含 .tsx 文件，而包装 .ts 文件位于“容器”文件夹中。

模块 NodeList.tsx 如下所示:

import * as React from "react";

export const NodeList = (props) => (
    <div id="NodeList">
        <ul>
        {props.items.map((item, i) => (
            <li key={i} >
                <span id={"Item_"+i}>{item}</span>
            </li>
            )
        )}
        </ul>
    </div>
    )

包装容器 NodeListContainer 是:

import { connect } from "react-redux";
import { Provider } from "react-redux";

import { Nodelist } from "../components/NodeList"

const nodesAsArrayOfType = (state, nodeType: string) => {
    console.log("Going for nodes of type ", nodeType)
    let a = state.data.model.nodes
    let k = Object.keys(a);
    let sub = k.filter((e) => {
                   return a[e].nodeType == nodeType
        }).map((e) => a[e])
    console.log("Got nodes ", sub)    
    return sub
}

const mapStateToProps = (state) => {
    var list = nodesAsArrayOfType(state, state.UIstate.focusNodeType).map((e) => {return JSON.stringify(e)})
    console.log("Returning ", list, list.length)
    return {
        items: list
    }
}

const mapDispatchToProps = (dispatch) => {
    return {
        newTextValue: (e) => {dispatch({type: "ON_CHANGE", text: e.target.value})}
    }
}

export const NodeListContainer = connect(
    mapStateToProps,
    mapDispatchToProps
    )(NodeList)

上面导入的 NodeList 被标记为错误消息

ERROR in ./src/containers/NodeListContainer.ts
(4,10): error TS2305: Module '"MyProject/src/components/NodeList"' has no exported member 'Nodelist'.

谁能提供任何关于这里可能发生的事情的见解？

如果您更正错字，您的代码应该可以正常工作。

代替

import { Nodelist } from "../components/NodeList"

你应该写:

import { NodeList } from "../components/NodeList"
//           ^ capital L
