在 DjangoGirls 教程中无法部署到 Heroku

Posted 2023-02-24

【中文标题】在 DjangoGirls 教程中无法部署到 Heroku

【英文标题】：Can't deploy to Heroku in DjangoGirls tutorial

【发布时间】：2015-06-11 12:57:02

【问题描述】：

我正在关注这个 DjangoGirls 教程：http://tutorial.djangogirls.org/en/deploy/README.html

当我尝试打开我的应用程序的 /admin 页面时，因为教程指出：

"由于到目前为止我们只为应用创建了管理视图，因此添加 admin/ 到网址（例如https://djangogirlsblog.herokuapp.com/admin/）查看 我们网络应用的工作页面。”

我仍然收到以下浏览器消息：

应用程序错误应用程序和您的页面发生错误 无法送达。请稍后再试。

如果您是应用程序所有者，请查看您的日志以了解详细信息。

这是我的项目布局：

djangogirls
|--mysite/
  |--blog/
  |--db.sqlite3
  |----manage.py
  |----mysite/
|--myvenv/
|--Procfile
|--requirements.txt
|--runtime.txt
|--.gitignore

这些是.gitignore的内容：

myvenv
__pycache__
staticfiles
local_settings.py
db.sqlite3
*.py[co]
*.pyc

这些是我的 mysite/wsgi.py 的内容

import os

from django.core.wsgi import get_wsgi_application

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings")

application = get_wsgi_application()

from whitenoise.django import DjangoWhiteNoise
application = DjangoWhiteNoise(application)

这些是Procfile的内容

web: gunicorn djangogirls.wsgi

教程告诉我们把mysite.wsgi复制出来，但是我在另一篇帖子里看到应该是project_name.wsgi，所以我改了这个。

runtime.txt：python-2.7.6

requirements.txt：

dj-database-url==0.3.0
Django==1.8
gunicorn==19.3.0
whitenoise==1.0.6
psycopg2==2.5.4

我知道这是一个很长的帖子，我提前为此道歉，我想提供更多信息而不是不够，我不完全明白在这种情况下我应该看什么重要的事情！

这是我的heroku日志：

这似乎是本教程中较难的阶段之一，我似乎无法弄清楚这个错误究竟意味着什么......提前感谢任何可以提供帮助的人，我真的很感激！

【问题讨论】：

从您的项目布局中，我假设 wsgi 文件在项目文件夹内的一级.. 在这种情况下，您可以使用 --pythonpath 给出确切的路径，如web: gunicorn --pythonpath app app.wsgi ??

你的项目是叫“mysite”还是“djangogirls”？

@RajaSimon 如果我进行更改，Heroku 会给我一条新消息“在服务器上找不到请求的 URL/。

@DanielRoseman 项目名称是 djangogirls，mysite 文件夹只是 django 使用的标准项目文件夹模板。抱歉，如果不清楚。

但这不是它的工作原理。当您执行django-admin.py createproject <project_name> 时，Django 会创建一个名为“project_name”的外部文件夹和一个名为“project-name”的内部文件夹也。他们应该是一样的，我不明白你是怎么得到一个叫“djangogirls”和一个叫“mysite”的。

【参考方案1】：

问题出在您的 Procfile 中。说明说要做：

web: gunicorn mysite.wsgi

但你已经把“djangogirls”而不是“mysite”。正如您在 cmets 中解释的那样，您的项目实际上称为“mysite”，而“djangogirls”只是包含文件夹的名称。

【讨论】：

您好 Daniel，感谢您的回复 - 这是我最初的设置，我不断收到相同的应用程序错误。我最终做出了这个改变web: gunicorn --pythonpath app app.wsgi，它奏效了。除此之外，每当我运行初始的django-admin startproject projectname 命令时，我不应该假设这是此类教程中提到的项目名称吗？因为我还没有接触到我的项目的布局，而且放 mysite.wsgi 肯定比 djangogirls.wsgi 更直观（我猜它只是需要完整路径才能知道它在哪里）

【参考方案2】：

如果你在根目录下项目文件夹，那么你必须给出确切的路径，这样 gunicorn 才能更好地服务..:)

点赞web: gunicorn --pythonpath app app.wsgi
