仅在生产环境中遇到“Not Found”错误

Question

未找到 在此服务器上找不到所请求的资源。

我认为问题出在我的setting.py 文件中：

from pathlib import Path
import os
import dj_database_url 

# Build paths inside the project like this: BASE_DIR / 'subdir'.
BASE_DIR = Path(__file__).resolve().parent.parent

# SECURITY WARNING: keep the secret key used in production secret!
SECRET_KEY = os.environ.get('SECRET_KEY', default='your secret key')

# SECURITY WARNING: don't run with debug turned on in production!
DEBUG = 'RENDER' not in os.environ

ALLOWED_HOSTS = []

RENDER_EXTERNAL_HOSTNAME = os.environ.get('RENDER_EXTERNAL_HOSTNAME')
if RENDER_EXTERNAL_HOSTNAME:
    ALLOWED_HOSTS.append(RENDER_EXTERNAL_HOSTNAME)

我的app.jsx是：

import { TaskFormPage } from "./pages/TaskFormPage";
import { Navigation } from "./components/Navigations";
import { TaskEditPage } from "./pages/TaskEditPage";
function App() {
  return (
    <BrowserRouter>
      <Navigation></Navigation>
      <Routes>
        <Route path="/" element={<Navigate to="/tasks" />} />
        <Route path="/tasks" element={<TaskPage />} />
        <Route path="/tasks-create" element={<TaskFormPage />} />
        <Route path="/tasks-edit" element={<TaskEditPage />} />
      </Routes>
    </BrowserRouter>
  );
}

export default App;

提前感谢您的帮助。我已经遇到这个错误两天了，我不知道该怎么办

我的 Web 应用程序面临一个令人费解的问题，我收到“未找到：在此服务器上找不到所请求的资源”错误，但仅限于生产环境。该应用程序在我的开发环境中运行良好。我已经检查了 URL，但仍然无法确定问题所在

我无法发表评论，所以我在这里写。我认为问题出在这一行：

STATIC_URL = 'static/'

应该是：

STATIC_URL = '/static/'
