Django + Heroku + S3: boto -> 赋值前引用的局部变量 "region_name"
Django + Heroku + S3: boto -> local variable "region_name" referenced before assignment
我遇到了一个非常奇怪的错误,这让我现在真的卡住了好几个小时。
我第一次使用 Heroku 进行部署,我使用 S3 存储媒体文件。我注意到的第一件事是,在安装 boto 和 django-storages-redux 之后,我从未成功进行过迁移,不知道为什么。不管怎样,我继续前进。
我的配置似乎在 AWS 中有效,因为我的静态文件确实在我第一次尝试时进入了我的存储桶,但是我有一些 img 文件没有通过,所以我决定重新安装 boto 和 django-registration- redux(看看它是否会正确迁移)。
最后它从未按预期迁移,现在我收到以下错误:
UnboundLocalError: local variable 'region_name' referenced before assignment
在我的 BOTO 包中,当 collectstatic 时。
我不明白为什么 migrate 不起作用以及为什么我在重新安装 boto 和 django-storages-redux 时开始出现此错误。
终端:
You have requested to collect static files at the destination
location as specified in your settings.
This will overwrite existing files!
Are you sure you want to do this?

好的,事情是这样的,如果您不使用 AWS 的默认区域,则在更新您的区域时必须小心,因为 S3 的格式因区域而异。
我在南美洲,因此我使用的是 sa-east-1(针对圣保罗)。
对我来说,当我更改设置时它起作用了:
