无法在virtualenv

Question

尝试使用命令django-admin.y startapp时，我一直收到导入错误消息。问题是，只有当我在我的virtualenv时才会出现问题。错误消息是：

  File "/Users/Opare/.virtualenvs/p2_dev/bin/django-admin.py", line 5, in <module>
    management.execute_from_command_line()
  File "/Users/Opare/.virtualenvs/p2_dev/lib/python3.4/site-     packages/django/core/management/__init__.py", line 354, in       execute_from_command_line

ImportError: No module named 'p2'

安装应用设置：

INSTALLED_APPS = (
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'movements',
'users')

Answer 1

您是否在程序中使用过p2模块？ 也许你真正的python环境和virtualenv python有所不同。 我猜你忘了在virtualenv中安装p2_dev包。 修复p2_dev时可能还缺少另一个包依赖项。

所以，为安全起见，我有一个建议，你可以用（在windows中）启动virtualenv：

virtualenv --system-site-packages virtualenv_project

然后，你将使用真正的python在virtualenv中获得相同的包。
