【问题描述】：

我正在尝试在 Heroku 上安装 Mezzanine (Django) 应用程序。我在项目的应用程序中有一个自定义主题。

我从 herokuapp 网站收到此错误：

Application Error
An error occurred in the application and your page could not be served. Please try again in a few moments.

If you are the application owner, check your logs for details.

我从“heroku 日志”中收到此错误：

这是我在 settings.py 中安装的应用程序变量（cc 是我的主题/应用程序名称）：

INSTALLED_APPS = (
    "cc",
    "django.contrib.admin",
    "django.contrib.auth",
    "django.contrib.contenttypes",
    "django.contrib.redirects",
    "django.contrib.sessions",
    "django.contrib.sites",
    "django.contrib.sitemaps",
    "django.contrib.staticfiles",
    "mezzanine.boot",
    "mezzanine.conf",
    "mezzanine.core",
    "mezzanine.generic",
    "mezzanine.blog",
    "mezzanine.forms",
    "mezzanine.pages",
    "mezzanine.galleries",
    "mezzanine.twitter",
    #"mezzanine.accounts",
    #"mezzanine.mobile",
    "gunicorn",
)

我的 requirements.txt 中有 gunicorn。此外，run_gunicorn 和 collectstatic 在我的 venv 中本地工作。为什么会这样？我遵循了这个：https://gist.github.com/joshfinnie/4046138 for my urls.py（请注意，我的 requirements.txt 是从 pip freeze > requirements.txt 生成的，所以它是最新的）。

这是我的 Procfile：

web: python manage.py collectstatic --noinput; python manage.py run_gunicorn -b 0.0.0.0:$PORT

标签： python django heroku mezzanine

【解决方案1】：

您的 Procfile 是在与 settings.py/manage.py 相同的路径中还是在外部？我遇到了类似的问题，并将我的个人资料在您的项目目录中上移一级。这就是工头在普通 Django 项目上的执行方式。但是，我正在使用 wsgi 运行它。

这是我的 Procfile

Procfile: 网页：python manage.py collectstatic --noinput； gunicorn your_project.wsgi -b 0.0.0.0:$PORT

【讨论】：

根据heroku日志，似乎“collectstatic”不存在。它也不能根据heroku日志导入wsgi模块。我的 Procfile 与 manage.py 和所有内容位于同一目录中，就像 Mezzanine 生成它一样。

【解决方案2】：

您似乎没有安装所有必需的应用程序，因此缺少 collectstatic 和 run_gunicorn。确保您的 requirements.txt 包含 Heroku 所需的所有必要包。

我在当前 Mezzanine 项目上的 requirements.txt 包含：

Cartridge==0.9.2
Django==1.6.2
Mezzanine==3.0.9
Pillow==2.3.1
bleach==1.4
boto==2.27.0
