在过去的一年里，我一直在使用 Django 开发一个应用程序。该应用程序是在 Debian 环境中编写的，开发和测试完全在 debain 机器中完成。

最近，我决定将应用程序移至本地基于 Mac OS X 的笔记本电脑上。使用端口我做了一个虚拟环境并从 github 拉我的项目。当我尝试运行服务器时，出现“不支持的语言环境设置”异常。

我的应用程序大量使用语言环境，我注意到虽然我机器中的语言设置设置为 en_US.UTF-8，而在 debian 机器上设置为 en_US.UTF8。我不知道破折号是否是它失败的原因。

我的应用程序使用 django-localeurl 为 i10n 和 i18n 创建语言代码 url 架构。

下面是我得到的例外

有什么想法可能导致这种情况吗？

更新：

当我登录到终端并写下“语言环境”时，我得到了以下信息

(mazban)Mohammed-Mughrabis-MacBook-Pro:mazban mo$ locale
LANG="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_CTYPE="en_US.UTF-8"

LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_ALL=

为了将来参考，我通过将 LC_ALL 导出为“en_US”解决了这个问题，这解决了我的问题

export LC_ALL='en_US'

您在代码中的哪个位置设置它？这对我有用，因为 Linux 和 OSX 机器各不相同，而且我在两者上都使用了我的代码，所以我写了这个异常块：

try:
    import locale
    locale.setlocale(locale.LC_ALL, 'en_US.utf8')
except Exception:
    try:
        locale.setlocale(locale.LC_ALL, 'en_US.UTF-8')
    except Exception as e:
        messages.error(request, 'An error occurred: {0}'.format(e))
