django項目不能在virtualenv工作

Question

我最近安裝了一個virtualenv並克隆了一個現有的django項目。當我運行python manage.py runserver，我發現了以下錯誤：

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 
    utility.execute()

    module = import_module('%s.management.commands.%s' % (app_name, name)) 
    File "/Users/user/eb-virt/lib/python2.7/site-packages/django/utils/importlib.py", line 35, in import_module 
    __import__(name)

    from django.views import static 
    File "/Users/user/eb-virt/lib/python2.7/site-packages/django/views/static.py", line 95, in <module> 
    template_translatable = ugettext_noop(u"Index of %(directory)s") 
    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 

當我嘗試做application-name/application python manage.py runserver，我得到以下錯誤：

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

這裏是應用程序目錄

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

首先，將您的application-name重命名爲application_name。 Dashes和Python源代碼只是引發問題，最好不要喚醒龍。

讓我們假設你已經把它放在~/work/application_name之內，即在你的virtualenv之外。

如果您未使用virtualenvwrapper創建virtualenv並且它沒有setup.py文件，請將其刪除（並安裝virtualenvwrapper）。

與virtualenvwrapper創建您的virtualenv：

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

-a添加現有目錄作爲項目目錄（把它放到蟒蛇路徑上這個的virtualenv）。 -r運行pip install -r上的論點（我假設application_name/requirements.txt存在）。

除了使用-a選項（假設application_name/setup.py存在），你可以在開發模式下安裝的軟件包：

cd ~/work 
pip install -e application_name 

這些要麼讓〜/工作/ Python的當模塊搜索路徑的應用程序名稱的一部分在跑。您的設置文件路徑必須相對於Python模塊搜索路徑上的目錄開始。

DJANGO_SETTINGS_MODULE環境變量因此應設置爲'application.settings'。
