ImportError:无法导入名称时区pythonanywhere

我试图在bash控制台中使用collectstatic来让我的CSS在pythonanywhere上的django应用程序上运行。

不幸的是,我得到一个错误:

23:49 ~/mysite/mysite $ python manage.py collectstatic

这是导入时区的.py

import datetime

from django.db import models
from django.utils import timezone

# Create your models here.

class Question(models.Model):
    question_text = models.CharField(max_length=200)
    pub_date = models.DateTimeField('date published')

    def __str__(self):
        return self.question_text

    def was_published_recently(self):
        now = timezone.now()
        return self.pub_date >= timezone.now() - datetime.timedelta(days=1)<= now
        was_published_recently.admin_order_field = 'pub_date'
        was_published_recently.boolean = True
        was_published_recently.short_description = 'Published recently?'

class Choice(models.Model):
    choice_text = models.CharField(max_length= 200)
    votes = models.IntegerField(default= 0)
    question = models.ForeignKey(Question, on_delete=models.CASCADE)

    def __str__(self):
        return self.choice_text

A:

如果我没有弄错,pythonanywhere默认使用Django1.3.7。 看起来Django timezone支持直到1.4版本才被添加:

https://docs.djangoproject.com/en/1.10/releases/1.4/#what-s-new-in-django-1-4

您应该将Django更新到最新版本(或至少是早期版本),并且一切都应该按预期工作(至少在时区)。 您可以通过从pythonanywhere配置文件上的控制台选项卡打开bash控制台并运行命令来升级:

$ pip install --upgrade django

或者在avirtualenv中安装较新版本:

$ mkvirtualenv myenv --python=/usr/bin/python3.4

$ pip install django

编辑:

我测试了我的第一个建议,并且无法让它在我的pythonanywhere帐户上工作(我认为这与pythonanywhere为其用户提供的权限有关)。 但是,使用第二种方法(即使用avirtualenv)确实可以安装最新版本的Django,其中确实包含django.utils.timezone中的时区支持。
