我犯了这个错误

js:38未捕获错误：在“连接（应用）”的上下文或道具中找不到“存储”。将根组件包装在中，或者将“store”作为道具显式传递给“Connect（App）”。

看起来您实际上没有使用正确的呈现：

<head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta.2/css/bootstrap.min.css">

你的代码
  • 您不使用
    提供商
    包装您的应用程序，也不使用
    路由器
    包装您的应用程序，而是直接使用
    应用程序
    （检查
    ReactDOM.render（…）
    行）
  • 您正试图将React应用程序装载到非DOM元素上。。。（同一行，第二个参数）
    • 现在说目标容器不是DOM element.Hmmm。实际上我没有检查，我会编辑我的答案，如果你也能粘贴你的
    index.html
    ，那就太好了。最后一个错误来自那里：）您有两个正在关闭的
    s。。。我猜这会混淆DOM。我的意思是你有两个结束的
    div
    s。
