ImportError:没有名为guardian的模块

时间:2015-06-26 22:00:33

标签: python django pip virtualenv django-guardian

我是Django的新手,所以一般来说我是大部分问题的原因,但我无法弄清楚为什么django-guardian 1.3应用程序不会安装。我在虚拟环境中使用Django 1.7,我的操作系统是Windows 8.1。

我按照pythonhosted.org/django-guardian/installation.html处的安装说明和pythonhosted.org/django-guardian/configuration.html处的配置,但在尝试运行程序时出错。

我添加了' guardian',ANONYMOUS_USER_ID,以及后端到我的settings.py

Django-guardian似乎安装在我的虚拟环境中,但它仍然没有找到它。我可能做错了什么想法? (或者对Django中每个对象权限的其他建议?)谢谢!

更新:我将问题缩小到了virtualenv。当我在不使用virtualenv的情况下安装模块时,django会发现它们应该如此。我还不确定我到底做错了什么,但是现在这个有用,考虑到我目前只在一个项目上工作。

我把问题缩小到了virtualenv。当我安装了   模块没有使用virtualenv,然后django发现它们喜欢它   应该。

每次运行django时都需要激活虚拟环境,否则你将继续遇到类似你所描述的问题。

激活虚拟环境(通过执行Scripts\activate.bat)将正确的环境变量设置为针对虚拟环境的Python安装运行所有Python命令。

如果在运行Python命令之前没有运行activate.bat文件,它们将针对系统范围的Python安装执行。

django工作的原因是因为你在没有激活virtualenv的情况下运行django;而且你也碰巧在全球Python环境中安装了django。

对于遇到同样问题的人:

原因可能是你没有拥有virtualenv文件夹及其所有内容,因此

sudo chown -R /path/to/venv

应该有用。
