reactjs - 刷新页面时，Django-React-Webpack 集成不输出更新的 React 组件

问题描述

我一直在尝试使用 Babel 和 Webpack 将 React 集成到 Django 应用程序中，但是很难运行更新的 .js 输出文件。

我相信我的问题来自 main.js 文件 Webpack 输出并没有反映来自我的 React 组件的更新。我的意思是，当我刷新页面时，我的服务器不会加载带有更新代码的 main.js 文件。

发生的情况是，当我刷新页面时，只有它在我的 python 终端上运行（大部分时间）：[20/Apr/2021 22:01:02] "GET / HTTP/1.1" 200 1509。虽然有时我的静态文件也运行，但这似乎是随机的：[20/Apr/2021 22:00:20] "GET /%20static%20/frontend/main.js HTTP/1.1" 304 0。所以发生的事情是 python当我刷新页面时，服务器很少为静态文件运行 GET。我想了解为什么会发生这种情况以及如何解决它。

这是我的文件夹结构：

这是我的代码：

index.js -

import App from "./components/App/App";

索引.html

<!DOCTYPE html>
<html>
    <head>
        {% load static %}
        <link rel="icon" href="{% static 'imgs/acmLogo.ico' %}" />
        <meta charset="UTF-8" />
        <meta name="viewport" content="width=device-width, initial-scale=1" />
        <title>ACM</title>
        <!-- link to css file -->
        <link rel="stylesheet" type="text/css" href="{% static 'css/index.css' %}" />
        
    </head>
    <body>
        <div id="main">
            <div id="app"></div>
        </div>

        <script src="{% static 'frontend/main.js' %}"></script>
    
    </body>
