这是我的 settings.py

我添加了

django.middleware.locale.LocaleMiddleware

在中间件

并且还添加了

from django.utils.translation import ugettext_lazy as _

并且还添加了

LOCALE_PATHS = (os.path.join(BASE_DIR, 'locale')

我还安装了 gettext 0.20.1。

我执行了

python manage.py makemessages -l en

和

python manage.py makemessages -l ko

当我运行 django 服务器时，

？：(翻译。E004( 您为"语言"设置中没有的LANGUAGE_CODE设置提供了一个值。

弹出错误。我该如何解决这个问题？我安装了 gettext 静态 0.20.1。在本地文件夹中，创建了 en 和 kr 文件夹，在这两个文件夹中，都有 django.po 和 django.mo。

Answer 1

错误非常明确：

？：(翻译。E004( 您为"语言"设置中没有的LANGUAGE_CODE设置提供了一个值。

LANGUAGE_CODE = 'ko-kr'

不在：

LANGUAGES = [
('ko', _('Korean')),
('en', _('English')),
]

Answer 2

自 Django 3.0 以来，LANGUAGE_CODE设置发生了变化：要将语言设置为韩语，您应该将LANGUAGE_CODE设置设置为"ko"，而不是"ko-KR"。
