django項目在virtualenv中不起作用

Question

我最近安裝了virtualenv並將一個現有的django項目克隆到其中。 當我運行python manage.py runserver ，出現以下錯誤：

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

  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

當我嘗試執行application-name/application python manage.py runserver ，出現以下錯誤：

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

這是應用程序目錄

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

Answer 1

首先，將您的application-name重命名為application_name 。 破折號和Python來源只是引人入勝的問題，最好不要驚醒巨龍。

假設您將其放在~/work/application_name ，即在virtualenv之外。

如果您沒有使用virtualenvwrapper創建virtualenvwrapper並且它沒有setup.py文件，則將其刪除（並安裝virtualenvwrapper ）。

使用virtualenvwrapper創建您的virtualenvwrapper ：

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

-a將現有目錄添加為項目目錄（將其放入此virtualenv的python路徑中）。 -r在參數上運行pip install -r （我假設存在application_name/requirements.txt ）。

除了使用-a選項（並假設存在application_name/setup.py ），您還可以在開發模式下安裝軟件包：

cd ~/work
pip install -e application_name

當Python運行時，這兩個都將〜/ work / application_name用作模塊搜索路徑的一部分。 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。

因此，應將DJANGO_SETTINGS_MODULE環境變量設置為'application.settings' 。
