我正在尝试使用Foreman / Honcho来管理基于Procfile的Django应用程序。当我启动应用程序查看正常python manage.py runserver时，一切正常。但是，当我通过honcho start或foreman start web启动应用时，我收到此错误：

这是尝试安装django-message模块。我和其他模块也有同样的问题。我也遇到了与django-webpack-loader相同的问题。我还应该提一下，我在virtualenv和停用时都收到错误。
这是安装django-messages的命令：
$> pip install django-messages
Requirement already satisfied (use --upgrade to upgrade): django-messages in ./lib/python2.7/site-packages
已安装的应用
INSTALLED_APPS = (
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'my_app',
'django_messages',
)
我不确定我可以提供哪些其他信息来帮助排除故障，但基本问题是我如何安装应用程序以与foreman / honcho合作？
答案 0 :(得分：3)
Honcho和Foreman不使用你的virtualenv中的Python可执行文件和库，虽然你没有包含你的Honcho Procfile，但只需调用python就可以使用系统范围的可执行文件和库。
不幸的是，你不能只调用/path/to/virtualenv/bin/activate作为Procfile的一部分，因为当其中一个子进程退出时，Honcho会退出，如in this Github issue thread所述。但是，您可以使用&&运算符在一个子shell中执行此脚本和python脚本，将它们链接在一起：
web: source venv/bin/activate && python manage.py
或者，您可以更好地修改您的wsgi.py包装器，以便在导入Django应用程序之前显式提取您的virtualenv库：
# Activate your virtual env
activate_env=os.path.expanduser("/path/to/virtualenv/bin/activate_this.py")
execfile(activate_env, dict(__file__=activate_env))
这些应该在导入任何模块（os之外）之前执行，以确保您的应用程序读取正确的站点库。
最后，Honcho本身支持在Procfile中使用.env文件，这些文件设置了运行进程的环境。此文件的格式与任何bash脚本相同。您可以使用.env文件将PYTHONPATH和PYTHONHOME设置为指向Virtualenv中的库，然后在Procfile中指定Virtualenv中的显式Python解释器。
.env文件
PYTHONHOME=/path/to/virtualenv/lib/python2.7
PYTHONHOME=
