PythonAnywhere 中的模块导入

Question

我正在尝试在 PythonAnywhere 上部署我的 Web 应用程序，但运行遇到了一个问题，它只是给我一个错误代码：未处理的异常页面。我在错误日志中收到以下错误：

  2016-07-21 06:41:49,331 :Error running WSGI application
    Traceback (most recent call last):
      File "/bin/user_wsgi_wrapper.py", line 154, in __call__

      File "/bin/user_wsgi_wrapper.py", line 170, in import_error_application

        application = load_wsgi_application()

        application = StaticFilesHandler(get_wsgi_application())
      File "/usr/local/lib/python3.5/dist-packages/django/core/wsgi.py", line 13, in get_wsgi_application
        django.setup()
      File "/usr/local/lib/python3.5/dist-packages/django/__init__.py", line 18, in setup
        apps.populate(settings.INSTALLED_APPS)
      File "/usr/local/lib/python3.5/dist-packages/django/apps/registry.py", line 85, in populate
        app_config = AppConfig.create(entry)
      File "/usr/local/lib/python3.5/dist-packages/django/apps/config.py", line 90, in create
        module = import_module(entry)
      File "/usr/lib/python3.5/importlib/__init__.py", line 126, in import_module
        return _bootstrap._gcd_import(name[level:], package, level)
    ImportError: No module named 'allauth'

我已经在服务器系统中安装了 django-allauth，并且在我的本地安装上一切正常。我还能够在控制台中获取到 allauth 的路径：

(venv) 06:49 ~/carmen (master)$ python -i /var/www/www_mywandermust_com_wsgi.py                                                                 
>>> import allauth
>>> print (allauth)
<module 'allauth' from '/home/gsussman/carmen/venv/lib/python3.5/site-packages/allauth/__init__.py'>

这是我的 WSGI 文件：

import os
import sys

path = '/home/gsussman/carmen'  # use your own username here
if path not in sys.path:
    sys.path.append(path)

os.environ['DJANGO_SETTINGS_MODULE'] = 'travelapp.settings'

from django.core.wsgi import get_wsgi_application
from django.contrib.staticfiles.handlers import StaticFilesHandler
application = StaticFilesHandler(get_wsgi_application())

Answer 1

allauth 安装在 virtualenv 中（称为 venv）。您的网络应用程序显然没有使用该 virtualenv（回溯中提到的 Django 在 /usr/local 中，而不是在 venv 中）
