已经3天了，我已经厌倦了这样，下面是我的设置文件：

正如您所看到的，我尝试将“django.middleware.locale.LocaleMiddleware”添加到MIDDLEWARE，并将“django.template.context_processors.i18n”添加到内容处理器。
网址：

from django.contrib import admin

    path('projects/', views.ProjectsListView.as_view()),
    path('i18n/',include('django.conf.urls.i18n')),
    path('', views.home),
]

意见：

def home(request):
    return render(request, 'home.html')

区域设置文件：

home.html:

    <input name="language" type="hidden" value="fa"/>
    <input type="submit" value="change"/>

{% trans "Hello" %}

当我检查我的浏览器cookies时djngo_language被设置为'fa'，但它不能将单词“Hello”翻译成“al-how "：Browser cookies
我试了几百次manage.py makemessages --all和manage.py compilemessages。我试了我在互联网上找到的每一个解决方案，但都不起作用。然后我删除了我的项目，并将其所有代码移到一个新项目中，但那也不起作用。我甚至多次尝试用不同的方式重新安装gettext。我还尝试使用{% blocktrans %}{% endblocktrans %}而不是trans标记。我“我简直要发疯了
我以为 Django 会把“你好”翻译成“你好”
