Heroku 内部服务器错误。参数验证错误。无效的存储桶名称“”：Python/Django

Question

这里绝对是初学者，将一个小网站部署到 Heroku 简直是一场噩梦。为了达到这一点，我已经解决了许多问题，但现在我似乎又碰壁了。我已将此作为 Heroku 的支持票提出，但除非这是他们方面的问题，否则我怀疑他们是否会给我一个明确的答案。

我可以成功部署到 Heroku，但是，当打开我的 Web 应用程序时，我只能看到 "Internal Server Error" 字样代替我的网站。我的 Sentry 日志收到 issue/error，如下所示：

我使用 django-cookiecuttter 作为我网站的基本模板。就在昨天，我阅读了针对 django-cookiecutter 针对另一个 Internal Server Error issue 提出的单独问题，我希望它也能帮助我（即使细节看起来不同），但我已经尝试从 [= 中删除 "min" 41=] 文件没有成功。

由于错误消息提到了存储和压缩器，这可能是 Django-compressor 相关或 whitenoise（我都安装了）？我已经研究过尝试根据说明 here 进行离线编译，但这可能已经过时了，因为我的网站在本地运行良好，如果我能提供帮助，我想避免不必要的编码。将不胜感激。

我正在使用 windows 与 Python 3.6.2 和 Django 2.0.2。我的生产静态设置如下：

# Static Assets
# ------------------------
STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage'

# COMPRESSOR
# ------------------------------------------------------------------------------
COMPRESS_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage'
COMPRESS_URL = STATIC_URL
COMPRESS_ENABLED = env.bool('COMPRESS_ENABLED', default=True)

提前致谢。

更新：

我仍然看到内部服务器错误，但是，我确定这与我设置存储桶的方式有关。我已按照此 tutorial 添加 IAM 组和策略，但我一定是做错了什么，因为我收到一条配置不正确的错误消息，其中包含以下详细信息：

Client error:An error occurred (403) when calling the HeadBucket operation: Forbidden

我在 AWS 中的政策如下（我已经尝试过几次迭代）：

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "VisualEditor0",
            "Effect": "Allow",
            "Action": [
                "s3:ListAllMyBuckets",
                "s3:HeadBucket",
                "s3:ListObjects"
            ],
            "Resource": "*"
        },
        {
            "Sid": "VisualEditor1",
            "Effect": "Allow",
            "Action": "s3:*",
            "Resource": [
                "arn:aws:s3:::mybucket/*",
                "arn:aws:s3:::mybucket"
            ]
        }
    ]
}

我很快就运行脱掉了头发，因为我似乎正在以惊人的速度拔掉它。毫无疑问，这又是一个小学生的错误，非常感谢您抽出时间来审阅。

Answer 1

错误消息表明您有一个无效的 AWS S3 存储桶名称：Invalid bucket name ""。空名称无效。

在cookiecutter-django中由this setting定义。

您需要在 AWS 中创建一个 S3 存储桶并在 Heroku 上设置环境变量DJANGO_AWS_STORAGE_BUCKET_NAME：

heroku config:set DJANGO_AWS_STORAGE_BUCKET_NAME='the-bucket-name'

编辑：

我不确定 Whitenoise + django-compressor + Heroku 有多少 cookiecutter-django 是最新的，但是 django-compressor 的回购中有 an issue opened可能很有趣。

Answer 2

回答我的 "Update" 第二个问题。我从头到尾再次浏览了 AWS 教程，虽然我认为我做的和以前完全一样，但这次它似乎起作用了，因为我现在遇到了另一个内部服务器错误 - 哦，快乐。我能想到的唯一感觉不同的是将策略分配给组，所以可能是我以前做的方式，我没能 link 它。

在再次打扰大家之前，我会继续寻找这个问题的答案，但是看到我很快回来请不要感到惊讶...
