我正在尝试让 Django 使用 virtualenv 工作。我已经在线获得了 hello world 页面。但是，现在似乎出了点问题，因为我的大多数命令都给了我关于 myProject.settings 的相同错误

(myenv)user@mint /opt/myenv/myProject $ python manage.py startapp polls
Traceback (most recent call last):
  File "manage.py", line 13, in <module>
    execute_from_command_line(sys.argv)

您settings.py必须可以通过 python 导入。这可以通过几种方式实现：

  • 如@amyangfei 所述，myProject您的环境中包含文件夹PYTHONPATH，即 insys.path

请注意，这PYTHONPATH是 python 用来构建它的系统环境变量sys.path，它的修改是依赖于操作系统的。对于 mac os，请参阅此参考资料，对于 windows，请参阅此参考资料。注意PYTHONPATH仅用于构造sys.path，其更改与os.environ['PYTHONPATH']=<some_new_value>没有显着影响。

但是，可以sys.path即时修改，以帮助import模块找到所需的包，请参见以下示例：

$ mkdir /tmp/tst
$ echo "print 'test'" > /tmp/tst/__init__.py
$ python -c "import tst"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: No module named tst
$ python -c "import os; os.environ['PYTHONPATH']+=';/tmp'; import tst;"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: No module named tst
$ python -c "import sys; sys.path.append('/tmp'); import tst;"
test
$ export PYTHONPATH=$PYTHONPATH:/tmp/
$ python -c "import tst"
test
  • 您可以python manage.py从包含 myProject.

要使后者工作，您的项目结构必须如下所示：

manage.py
myProject/
    settings.py
  • 最后一个选项，如果您的 manage.py 和 settings.py 位于同一位置，请将环境变量更改DJANGO_SETTINGS_MODULE为settings而不是myProject.settings，或python manage.py使用--settings=settings参数运行。

你有没有尝试过这样的事情？也许会奏效。

python manage.py startapp polls --settings=myProject.settings

检查是否'/opt/myenv/myProject'在您的 python sys.path 中。（参考 python 文档：sys.path[0]，是包含用于调用 Python 解释器的脚本的目录。如果脚本目录不可用（例如，如果以交互方式调用解释器或从标准输入），path[0] 是空字符串）（http://docs.python.org/2/library/sys.html#sys.path）
