Question

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，我收到了一个错误：

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

    from django.utils import timezone
ImportError: cannot import name timezone

以下是导入时区的.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

如果我没弄错的话，pythonanywhere默认使用Django 1.3.7。看起来直到版本1.4才添加Django时区支持：

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（或者至少是早期版本），并且所有内容都应该按预期工作（至少使用时区）。您可以通过在pythonanywhere配置文件的控制台选项卡中打开bash控制台并运行命令来进行升级：

$ pip install --upgrade django

或在virtualenv中安装较新版本：

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

$ pip install django

我测试了我的第一个建议，并且无法让它在我的pythonanywhere帐户上运行（我认为它与pythonanywhere为其用户提供的权限有关）。但是，使用第二种方法（即使用virtualenv）确实安装了最新版本的Django，其中包括django.utils.timezone中的时区支持。
