当组件重复调用setState内部componentWillUpdate或时,可能会发生这种情况componentDidUpdate.React限制嵌套更新的数量以防止无限循环.

authenticationRoute由于此错误,我无法路由到目的地.

控制台输出:

index.js:1446组件中出现上述错误:

in Redirect (at Auth.jsx:101)
in div (at Auth.jsx:116)
in Auth (created by Context.Consumer)
in Connect(Auth) (created by Route)
in Route (at App.js:27)
in Switch (at App.js:26)

我正在尝试在React应用程序上显示pdf，并且收到以下警告：

/node_modules/react-pdf/node_modules/pdfjs-dist/build/pdf.js关键依赖项：require函数以无法静态提取依赖项的方式使用

Vscode在导入功能下告诉我这一点。

找不到模块'react-pdf'的声明文件

已经尝试运行npm install，npm install react-pdf然后重新安装软件包

import React, { Component } from 'react';
import { Document } from 'react-pdf';
import sample from 'file location'
export default class viewer extends Component {
    render() {
        return (
            <div>
                <Document
                    file={sample}
                    onLoadSuccess={this.onDocumentLoadSuccess}
                >
                </Document>
            </div>
        );
    }
}
