django项目不能在virtualenv工作

Question

我最近安装了一个virtualenv并克隆了一个现有的django项目。当我运行python manage.py runserver，我发现了以下错误：

Traceback (most recent call last): 
    File "manage.py", line 22, in <module> 
    execute_from_command_line(sys.argv) 
    File "/Users/user/eb-virt/lib/python2.7/site-packages/django/core/management/__init__.py", line 443, in execute_from_command_line

    File "/Users/user/eb-virt/lib/python2.7/site-packages/django/utils/translation/__init__.py", line 75, in gettext_noop 
    return _trans.gettext_noop(message) 
    File "/Users/user/eb-virt/lib/python2.7/site-packages/django/utils/translation/__init__.py", line 48, in __getattr__ 
    if settings.USE_I18N: 
    File "/Users/user/eb-virt/lib/python2.7/site-packages/django/utils/functional.py", line 184, in inner 
    self._setup() 
    File "/Users/user/eb-virt/lib/python2.7/site-packages/django/conf/__init__.py", line 42, in _setup 
    self._wrapped = Settings(settings_module) 
    File "/Users/user/eb-virt/lib/python2.7/site-packages/django/conf/__init__.py", line 95, in __init__ 
    raise ImportError("Could not import settings '%s' (Is it on sys.path?): %s" % (self.SETTINGS_MODULE, e)) 
ImportError: Could not import settings 'application-name.settings' (Is it on sys.path?): No module named application-name.settings 

当我尝试做application-name/application python manage.py runserver，我得到以下错误：

python: can't open file 'manage.py': [Errno 2] No such file or directory

这里是应用程序目录

application-name/ 
    manage.py 
    application/ 
     __init__.py 
     urls.py 
     wsgi.py 
     settings.py

首先，将您的application-name重命名为application_name。 Dashes和Python源代码只是引发问题，最好不要唤醒龙。

让我们假设你已经把它放在~/work/application_name之内，即在你的virtualenv之外。

如果您未使用virtualenvwrapper创建virtualenv并且它没有setup.py文件，请将其删除（并安装virtualenvwrapper）。

与virtualenvwrapper创建您的virtualenv：

mkvirtualenv -a ~/work/application_name -r ~/work/application_name/requirements.txt eb_virt 

-a添加现有目录作为项目目录（把它放到蟒蛇路径上这个的virtualenv）。 -r运行pip install -r上的论点（我假设application_name/requirements.txt存在）。

除了使用-a选项（假设application_name/setup.py存在），你可以在开发模式下安装的软件包：

cd ~/work 
pip install -e application_name 

这些要么让〜/工作/ Python的当模块搜索路径的应用程序名称的一部分在跑。您的设置文件路径必须相对于Python模块搜索路径上的目录开始。

DJANGO_SETTINGS_MODULE环境变量因此应设置为'application.settings'。
