我收到一個非常奇怪的錯誤，讓我真的陷入了幾個小時的困境。Django + Heroku + S3：boto - >局部變量「region_name」在作業前引用
我第一次使用Heroku進行部署，並使用S3作爲媒體文件。我注意到的第一件事是，在安裝boto和django-storage-redux後，我從來沒有成功遷移過，不知道爲什麼。無論如何，我繼續前進。
我的配置似乎在AWS中工作，因爲我第一次嘗試它時，我的靜態文件確實進入了我的存儲桶，但我有一些img文件沒有通過，因此我決定重新安裝boto和django-registration-redux （看看它是否會正常遷移）。
最後，它從來沒有按預期遷移，現在我得到以下錯誤：collectstatic時
UnboundLocalError: local variable 'region_name' referenced before assignment 我BOTO包。
我不明白爲什麼遷移將無法正常工作，爲什麼我開始時，我得到這個錯誤重新安裝博託和Django的儲存 - 終極版。
終端：
You have requested to collect static files at the destination
location as specified in your settings.
This will overwrite existing files!
