我是React的新手,但我遇到了一些问题。我在项目中添加了一个新组件,作为"react-customized-progressbar"。我有以下黄色的文件。这些是我创建的文件。
问题指向
Error in ./src/example1.js 6:0 - 73没有找到模块:错误:无法解析"C:\Alex Maricoiu\Projects\React projects\project1\src"中的. "/CircularProgressBarContainer "无法编译。CircularProgressBarContainer. tsx具有以下代码:
import React, {FunctionComponent} from "react";
import ICustomIndicatorProperties from './IProgressBarProperties';
import ProgressBar from 'react-customizable-progressbar'
const CustomProgressIndicator : FunctionComponent<ICustomIndicatorProperties> = ({value, title}) => {
return (
<div className="text-and-value" style={{width: "29em"}}>
<div className="title-text">{title}</div>
<div className="custom-progress-bar">
<ProgressBar
radius={100}
progress={value}
strokeWidth={18}
strokeColor="#5d9cec"
strokeLinecap="square"
trackStrokeWidth={18}
>
<div className="indicator">
<div>{value}%</div>
</div>
</ProgressBar>
</div>
</div>
)
};
export default CustomProgressIndicator;
Example1.js:
import {useState} from 'react';
import {CustomProgressIndicator} from './CircularProgressBarContainer';
function Button(props) {
return (
<button onClick={props.onClickFunc}>
Increment by 1
</button>
);
}
function Display(props){
// eslint-disable-next-line no-undef
const [counter, setCounter] = useState(0);
const incrementValue = () => setCounter(counter+1);
return (
<div>
<Button onClickFunc={incrementValue}/>
<b> Current value is: {counter}</b>
<CustomProgressIndicator
value={counter}
title ='Indicator Exercise 1'
/>
</div>
)
}
function App(props){
return (
<div>
<Display />
</div>
)
}
export default App;
接口文件具有(IProgressBarProperties. tsx):
interface ICustomIndicatorProperties {
title: string;
value: number;
}
export default ICustomIndicatorProperties;
和Main. js:
import './Main.css';
import Example1 from './example1';
import { Component } from 'react';
class App extends Component {
render(){
return (
<>
<div className='header'>Alex React Examples</div><div className='content'>
<h3>Example #1</h3>
<div id='example1Node'>
<Example1 />
</div>
</div>
</>
);
}
}
export default App;
Index.js:
import React from 'react';
import ReactDOM from 'react-dom/client';
import MainApp from './Main';
const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(
<React.StrictMode>
<MainApp />
</React.StrictMode>
);
package.json:
{

}
我使用的是Node.js 19.3.0。我试图从浏览器控制台找到问题所在,但我被卡住了。我试图删除node_modules并在终端中再次运行此命令:npm安装。如果我删除了对文件的引用,其中是进度条的应用程序正在工作,但与失败的错误提到。有什么办法可以找到解决该错误?
先谢谢你

尝试将
import {CustomProgressIndicator} from './CircularProgressBarContainer';
替换为import CustomProgressIndicator from './CircularProgressBarContainer';
,因为您使用的是 export default。大括号用于正常(非默认)export。或者从 export default 中删除 default。yws3nbqq2#
更新/解决
我带着一个解决方案回来了。在我稍微调查了一下之后,似乎有一个错误的路径指向创建的本地模块(指向本地TSX文件)。更新是在Example1.js中。当我输入路径时,intellisense向我显示了正确的导入方式,我按下Enter键以完成路径。这很好。导入如下所示
问题就在这里,我纠正得像是风箱,效果很好。
最后的结果是这样的。标记为黄色的组件是问题所在。x1c 0d1x
