Question

我习惯于将Spring应用程序推送到Cloud Foundry。这是我第一次推送Django应用。上传完成后，它显示：

> Waiting for app to start...
Start unsuccessful

我的应用程序项目结构如下：

.gitignore
Procfile
README.md
/app
    __init__.py
    settings.py
    urls.py
    wsgi.py
/assets
    __init__.py
    admin.py
    apps.py
    data_generator.py
    models.py
    tests.py
    urls.py
    views.py
    /migrations
        __init__.py
/tokentype
    __init__.py
    admin.py
    apps.py
    models.py
    tests.py
    urls.py
    views.py
    /migrations
        __init__.py
db.sqlite3
log_storage.log
manage.py
manifest.yml
/repo
    assetmanagement-3.9-py3-none-any.whl
    mindsphere_core-0.1.0-py3-none-any.whl
requirements.txt
runtime.txt
sdk_util.py

我的runtime.txt包含python-3.5.x。
我的Procfile包含web: python manage.py migrate && python manage.py runserver。
我的requirements.txt具有所有必需的要求，包括Django和djangorestframework。

并且manifest.yaml具有以下内容：

applications:
- name: pythondemoapp
  instances: 1
  randon-route : true
  path: .
  memory: 1GB
  env:
    HOST_ENVIRONMENT: eu1-int

在应用无法启动后运行cf logs pythondemoapp --recent时，出现以下日志，其中抱怨了几个问题：

ModuleNotFoundError: No module named 'django' (but I have this in my requirements.txt)
Failed to make TCP connection to port 8080: connection refused.（我无法理解为什么它在http://127.0.0.1:8000/处（即本地主机）启动开发服务器）
AttributeError: module 'pip._internal' has no attribute 'utils'

请查看日志：

Answer 1

我正在为将来的访客添加解决方案。我的应用程序使用了django随附的开发服务器（WSGI）。因此，当我的启动命令“ python manage.py runserver”正在运行时，它试图在

处启动应用程序

http://127.0.0.1:8000/

因此，我添加了生产就绪服务器“ gunicorn”，并将procfile中的启动命令更改为

web: python manage.py migrate && gunicorn app.wsgi --log-file -

此后，该应用程序成功在Cloud Foundry中启动。

无法使用Cloud Foundry push
