Django {％include％}模板标签不适用于文件

我只是租用VPS试图发布一个Django项目。在我的电脑的调试模式下运行正常，但是当我尝试在VPS中运行调试模式时出现错误：

Django Version:     1.8.5
Exception Type:     SyntaxError
Exception Value:      
invalid syntax (inbox.py, line 39)

Exception Location:     /usr/lib/python3.4/importlib/__init__.py in import_module, line 109
Python Executable:  /usr/bin/python3
Python Version:     3.4.3


Error during template rendering

In template /webapps/rusc/rusc/templates/base.html, error at line 66:

63          </div>
64  
65          <div id="div_user">
66  

      {%  include "usermenu.html" %}



67          </div>
68      </div>

在＆＃34; usermenu.html＆＃34;我有这个导致问题的负载

{% load notifications_tags %}
{% load inbox %}

如果我在＆＃34; base.html＆＃34;中加载它{％extends％}标记无效：

Django Version:     1.8.5
Exception Type:     SyntaxError
Exception Value:    

invalid syntax (inbox.py, line 39)

Exception Location:     /usr/lib/python3.4/importlib/__init__.py in import_module, line 109

In template /webapps/rusc/rusc/templates/rusc.html, error at line 1

1   

      {% extends "base.html" %}



2   
3   
4   {%  block content %}
5       <br />
6       <br />

如果我在rusc.html上加载，我仍然有 SyntaxError 但没有附加html文件，只返回渲染：

我可以在哪里加载这些数据？

奇怪的是我在Windows和Ubuntu中安装了相同的项目并且工作正常，这个错误只出现在OVH的Ubuntu VPS中（据我所知）。

任何帮助都将不胜感激。

inbox.py 是Django-messages的文件： https://github.com/arneb/django-messages/blob/master/django_messages/templatetags/inbox.py 

from django.template import Library, Node, TemplateSyntaxError

class InboxOutput(Node):
    def __init__(self, varname=None):
        self.varname = varname

    def render(self, context):
        try:
            user = context['user']
            count = user.received_messages.filter(read_at__isnull=True, recipient_deleted_at__isnull=True).count()
        except (KeyError, AttributeError):
            count = ''
        if self.varname is not None:
            context[self.varname] = count
            return ""
        else:
            return "%s" % (count)

def do_print_inbox_count(parser, token):
    """
    A templatetag to show the unread-count for a logged in user.
    Returns the number of unread messages in the user's inbox.
    Usage::

        {{ my_var }}

    """
    bits = token.contents.split()
    if len(bits) > 1:
        if len(bits) != 3:
            raise TemplateSyntaxError("inbox_count tag takes either no arguments or exactly two arguments")
        if bits[1] != 'as':
            raise TemplateSyntaxError("first argument to inbox_count tag must be 'as'")
        return InboxOutput(bits[2])
    else:
        return InboxOutput()

register = Library()
register.tag('inbox_count', do_print_inbox_count)

问题似乎是指您的VPS上使用的django-messages应用程序版本。您正在使用python3.4版本，如果您只是使用pip install安装django_messages，那么您将面临旧的Exception语法问题（仅限39行）：

raise TemplateSyntaxError, "first argument to inbox_count tag must be 'as'"

它已在主分支https://github.com/arneb/django-messages/commit/659a3dd710051f54e3edc1d76cdfb910d7d04c1a#diff-2006ff4f62d84a3bee25f8b1823d6a5fL39中更改，因此如果您尝试更新django-messages应用程序版本，您将摆脱SyntaxError问题。
