我一直在犯这个错误：

“东部标准时间”时区未获承认

以下是代码：

def get_context_data(self, **kwargs):
    # Call the base implementation first to get a context
    context = super(IndexView, self).get_context_data(**kwargs)
    """Return the last five published posts."""
    context['latest_post_list'] = Post.objects.order_by('-pub_date')[:5]
    context['archives'] = Post.objects.datetimes('pub_date', 'month', order='DESC')     
    return context;

在我的模板中：

{% for archive in archives %}
    <li><a href="#">{{ archive.month }} {{ archive.year }}</a></li>
{% endfor %}

在我的背景下：

TIME_ZONE = 'America/Montreal'

我想做的是建立一个档案系统。如果有可能得到不同的月份和年份，就会有任何职位。

这真的很难分辨，因为我看不到您的数据，但是它看起来像是在某个时区的数据字段/列中有“东方标准时间”。

Python使用IANA/Olson时区，通过pytz包。所以你的数据应该是美国东部时间的“美国/纽约”。

安装了pytz，错误消失了：

pip install pytz

这可能是Windows的唯一问题，请参阅备注带区。
