virtualenv 不导入项目设置

Question

美好的一天，遇到一个奇怪的问题已经 3 天了，到目前为止我还没有找到任何解决方案。我读了很多答案，但到目前为止它们仍然没有帮助我。这是我收到的项目回溯：

(empire243)drcongo@congodevpro:~$ django-admin check
Traceback (most recent call last):
  File "/home/drcongo/.virtualenvs/empire243/bin/django-admin", line 11, in <module>
    sys.exit(execute_from_command_line())
  File "/home/drcongo/.virtualenvs/empire243/lib/python3.4/site-packages/django/core/management/__init__.py", line 351, in execute_from_command_line
    utility.execute()

    mod = importlib.import_module(self.SETTINGS_MODULE)
  File "/home/drcongo/.virtualenvs/empire243/lib/python3.4/importlib/__init__.py", line 109, in import_module

    from empireMarket.settings import *
ImportError: No module named 'empireMarket'
(empire243)drcongo@congodevpro:~$

当我这样做时：echo $DJANGO_SETTINGS_MODULE，它 returns 我的 dev_settings.py 是正确的。
当我执行 add2virtualenv 时，有我的实例设置目录的路径。
当我在 virtualenv 中执行 which django-admin 或 which django-admin.py 时 returns : /home/drcongo/.virtualenvs/empire243/bin/django-admin and /home/drcongo/ .virtualenvs/empire243/bin/django-admin.py

这是我的 dev_settings:

dev_settings.py

from empireMarket.settings import *

一切正常，但我仍然收到导入错误。任何帮助都会非常有用。我正在使用 python3

看起来项目没有安装到 virtualenv 中。

通常的做法是为你的包定义一个setup.py，它应该进入包的根目录（通常是包含src的目录）。最小的可能看起来像这样：

empireMarket/setup.py

from setuptools import setup, find_packages

setup(
    name='empireMarket',
    package_dir={'': 'src'},
    packages=find_packages('src'),
    include_package_data=True,

    install_requires=[
        'Django',
    ]
),

一旦你有了它，你可以使用 pip install <dir> 或 pip install -e <dir> 将你的包安装到 virtualenv 中。

完成后，导入 empireMarket.settings 应该可以了。
