Fabric，无法在Django上获取默认语言环境

问题描述

我有以下django管理命令:

I have the following django management command:

fabrictest.py

fabrictest.py

from django.core.management.base import NoArgsCommand
import locale

class Command(NoArgsCommand):

    def handle_noargs(self, **options):
        print locale.getdefaultlocale()

我可以在本地运行什么

$ /home/user/env/bin/python manage.py fabrictest
('en_US', 'UTF-8')

但是，当我使用以下结构任务远程运行命令时

However, when I run the command remotely using the following fabric task

@task
def test():
    # run manage.py using the python bin from the virtualenv

    with cd(env.project_root):
        run("/home/user/env/bin/python manage.py fabrictest")

我得到以下输出

[server] Executing task 'test'
[server] run: /home/user/env/bin/python manage.py fabrictest
[server] out: (None, None)

为什么我会得到(None, None)而不是('en_US', 'UTF-8')?这会为其他一些管理脚本(即创建超级用户时的syncdb)产生错误.

Why do I get (None, None) instead of ('en_US', 'UTF-8')?. This generates errors for some other management scritps (namely, syncdb when creating the superuser).

推荐答案

来自文档:

...如果值不能，则代码和编码可以为无" 被确定.

...code and encoding can be None in case the values cannot be determined.

如果您的程序无法使用'C'语言环境运行，请调用setlocale()和/或设置适当的环境变量，例如LANG.

If you program can't run using the 'C' locale then call setlocale() and/or set appropriate environment variables e.g., LANG.
