Django国际化（I18N）没有改变文本(Django Internationalization (I18N) not changing text)

 我创建了一个简单的网站来测试国际化，但我不能按照我想要的方式工作。 我想更改views.py中的消息而不检查request.LANGUAGE_CODE （正确显示）。 
 
 我可以使用前缀/ en /和/ pt-br /转到URL，但它们不会更改模板中的文本。 
 
 我试过跑 
 
django-admin makemessages --locale=pt_BR
 
 我换了线 
 
#: mytest/views.py:7
msgid "Welcome to my site."
msgstr "Bem vindo ao meu site."
 
 跑 
 
django-admin compilemessages --locale=pt_BR
 
 PS :(即使它错了，我也试过django-admin makemessages / compilemessages --locale = pt-br） 
 
 我在settings.py中更改了什么（添加了我的应用程序，添加了区域设置中间件，添加了一些内部化设置） 
 
INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',

    'django.contrib.staticfiles',
    'mytest'

 views.py

from django.utils.translation import ugettext_lazy as _

def index(request):
    print(request.LANGUAGE_CODE) #this shows correctly the prefix in the url
    output = _("Welcome to my site.")
    context = {"test_translate": output}
    return render(request, "mytest/index.html", context)
 
 urls.py 
 
from django.conf.urls.i18n import i18n_patterns
from mytest import views

urlpatterns += i18n_patterns(
    url(r'^$', views.index, name='index'),
)

I created an simple website to test internationalization, but I can't make it work the way I wanted. I would like to change messages in my views.py without checking the request.LANGUAGE_CODE (which is showing correctly).
 
I can go to the urls with prefix /en/ and /pt-br/ but they don't change the text in the template. 
 
I tried running 
 
django-admin makemessages --locale=pt_BR
 
I changed the lines
 
#: mytest/views.py:7
msgid "Welcome to my site."
msgstr "Bem vindo ao meu site."
 
ran 
 
django-admin compilemessages --locale=pt_BR
 
PS: (even though it is wrong, I tried django-admin makemessages/compilemessages --locale=pt-br as well)
 
What I changed in settings.py (added my app, added locale middleware, added some internalization settings)

    'django.contrib.contenttypes',

    'mytest'
]
