请我在这里需要你的帮助。我在我的应用程序中启用了 Django 国际化，即使调试为 False，它也能正常工作。但最近我尝试为我的服务器错误和找不到页面错误提供 500.html 和 404.html。现在，Internal Error: /当您访问主页时，该应用程序会显示“”。示例localhost:8000会给您服务器错误。但如果我手动输入网址，localhost:8000/en/它就可以正常工作。任何人都可以在这方面为我照亮更多的光。以下是它在回溯时提供的错误。

经过一番研究，添加prefix_default_language=False,insidei18n_patterns停止了错误。虽然现在 urllocalhost:8000不会重定向到localhost:8000/en/访问时，但它工作正常。

urlpatterns += i18n_patterns(
     path('', view.Home, name="Home"),
     prefix_default_language=False,
)
