无法在AWS弹性Beanstalk上找到Django App的模块 [英] Cannot locate modules of Django App on AWS Elastic Beanstalk

问题描述

我正在尝试在AWS Elastic Beanstalk上运行一个Django应用程序，但是它似乎可能是一个PYTHONPATH或者virtualenv问题，而且我无法想象出来。

I'm trying to make a Django app run on AWS Elastic Beanstalk, but am stuck with what appears like it might be a PYTHONPATH or virtualenv problem, and I can't figure it out.

当我尝试在浏览器中加载一个页面时，我得到了黄色的Django错误屏幕（我仍然处于调试模式）：

When I try to load a page in my browser, I get the yellow Django error screen (I'm still in debug mode):

Exception Value: No module named views.rest
Exception Location: /opt/python/current/app/project/urls.py in <module>, line 3
Python Executable:  /opt/python/run/venv/bin/python
Python Version: 2.7.5
Python Path:    
['/opt/python/run/venv/lib/python2.7/site-packages',
 '/opt/python/current/app',
...

我的urls.py导入是：

My urls.py imports are:

from django.conf.urls import patterns, include, url
from django.contrib import admin
from myapp.views.rest import *

如果我进入EC2实例，路径看起来正确; / opt / python / current / app 包含我的应用程序，包括 /opt/python/current/app/myapp/views/rest.py 。

If I ssh into the EC2 instance, the path looks right; /opt/python/current/app contains my application, including /opt/python/current/app/myapp/views/rest.py.

我的目录结构包含（当然也有更多）：

My directory structure contains (there's more, too, of course):

app/
    .ebextensions/
        packages.config
        python.config
    .elasticbeanstalk/
        config
        optionsettings.myapp-deployment-env
    project/
        settings.py
    application.py
    myapp/
        views/
            rest.py
            views.py
            __init__.py

在 __ init __。py 我有：

In __init__.py I've got:

from myapp.views.views import *
from myapp.views.rest import *

该问题不是特定于这些文件 - 如果我添加另一个导入到urls。 py也失败了，所以就像没有找到该应用程序。

The issue is not specific to these files though - if I add another import to urls.py that fails too, so it's like it's not finding the app at all.

packages:
  yum:
    postgresql-devel: []

在 python.config 我有（试图加载virtualenv，这可能不是必需的？）

In python.config I've got (in an attempt to load the virtualenv, which might not be necessary?)

container_commands:
  00_activate:
    command: "source /opt/python/run/venv/bin/activate"
  01_make_admin_executable:
    command: "chmod +x scripts/createadmin.py"
    leader_only: true
  02_make_executable:
    command: "chmod +rx application.py"
    leader_only: true
  03_syncdb:
    command: "python manage.py syncdb --noinput"
    leader_only: true
  04_collectstatic:
    command: "python manage.py collectstatic --noinput"

option_settings:
  - option_name: AWS_SECRET_KEY
    value: mykey
  - option_name: AWS_ACCESS_KEY_ID
    value: myaccesskeyid
  - option_name: application_stage
    value: "staging"

如果对其他配置文件有帮助，请快乐列出。它们包括设置位置，但没有对PYTHONPATH等的具体引用。

Happy to list the other config files if they're helpful. They do include the settings location but no specific reference to PYTHONPATH etc.

[aws:elasticbeanstalk:application:environment]
DJANGO_SETTINGS_MODULE=project.settings

我已经运行 eb update 和 git aws.push 。

真的很挣扎着这个！我第一次尝试使用AWS部署，显然错过了一些重要的事情。真的感谢帮忙，如果有人知道我错过了什么。

Really struggling with this one! My first attempt at an AWS deployment so have obviously missed something important. Really appreciate the help if anyone knows what I've missed.

推荐答案

原来是一个mod_wsgi vs Django开发服务器问题。 Graham Dumpleton的这篇文章非常有助于理解它（它不能被阅读）。

This turned out to be a mod_wsgi vs Django development server issue. This post by Graham Dumpleton was extremely helpful in understanding it (it can't be skim-read).

mod_wsgi需要被告知我的网站的位置。我的WSGI文件（application.py）现在看起来像这样，导入工作：

mod_wsgi needs to be told of the location of my site. My WSGI file (application.py) now looks like this, and the imports work:

import os
import sys

sys.path.insert(0, '/opt/python/current/app')

os.environ['DJANGO_SETTINGS_MODULE'] = 'project.settings'

from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()
