django在Mac OS X上不受支持的语言环境设置

Question

我一直在使用Django开发一个应用程序过去一年。该应用程序是在Debian环境下编写的，开发和测试完全是在一台虚拟机上完成的。

最近，我决定将应用程序移到本地基于Mac OS X的笔记本电脑上。使用端口的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“不支持的区域设置”异常。

我的应用程序严重使用语言环境，我注意到虽然我的机器中的语言设置是为en_US.UTF-8设置的，而在debian机器上是en_US.UTF8。我不知道破折号是不是失败的原因。

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

任何想法，就是可能会造成这个？

更新：

，当我登录到终端，并写下了“区域设置”我得到了下面

(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_MESSAGES="en_US.UTF-8" 
LC_MONETARY="en_US.UTF-8" 
LC_NUMERIC="en_US.UTF-8" 
LC_TIME="en_US.UTF-8" 
LC_ALL= 

Answer 1

凡在你的代码，你设置呢？这适用于我，因为Linux和OSX机器有所不同，我使用我的代码，我写这个异常块：

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)) 

Answer 2

以供将来参考，我通过导出LC_ALL为“EN_US”解决了这个问题，其解决我的问题

export LC_ALL='en_US'
