django unsupported locale setting on Mac OS X

Question

I've been developing an application using Django for the past a year. The application was written in a Debian environment, the development and testing was entirely done in a debain machine.

Recently, I decided to move the application to my local Mac OS X based laptop. using port's I did a virtual environment and pulled my project from github. When I try to runserver, am getting "unsupported locale setting" exception.

My application uses locale heavily, I noticed though the language setting in my machine is set for en_US.UTF-8 while on the debian machine it was en_US.UTF8. I don't know if the dash is the reason why it is failing though.

My application is using django-localeurl for creating language code url schema for i10n and i18n.

below is the exception am getting

any idea's what could be causing this?

update:

when I logged in to terminal and wrote "locale" I got the below

(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

Where in your code do you set it? This works for me, since the Linux and OSX machines vary and I use my code on both, I wrote this exception block:

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

for future reference, I solved the problem by exporting LC_ALL as 'en_US' which solved my problem

export LC_ALL='en_US'
