這是我在嘗試推送時遇到的錯誤，一周前一切正常，我可以毫無問題地部署。現在，當我嘗試部署時，我總是收到此錯誤，因為我無法同時滿足 python-dateutil==2.8（應用程式需要）和 python-dateutl==1.5（heroku 需要）。不知道為什么這開始發生。（在全球范圍內更新了 heroku，但沒有任何改變）。有一個包裝器Heroku3，但我似乎無法使用它來部署，當我在 env 中安裝它時，heroku3 命令不存在并且它在 npm 上不可用，所以我所能做的就是用它撰寫 python 代碼。如果有人知道如何解決這個問題，將不勝感激。

remote: The user requested python-dateutil==2.8.2
remote: botocore 1.21.39 depends on python-dateutil<3.0.0 and >=2.1

unversion python-dateutil 如果不起作用，請訪問https://pypi.org/project/python-dateutil/#history 并執行以下操作，嘗試多次嘗試，每次都部署到 heroku
- 得到了 requirements.txt 并更改為 python-dateutil==2.5.1 如果不起作用嘗試較低版本
- 將 Heroku 版本更改為 heroku3==3.1.0
uj5u.com熱心網友回復：
如果在之前的部署中一切正常，您可以登錄 Herokuhttps://dashboard.heroku.com/并打開應用程式的控制臺并獲取當前安裝的庫。
如果您不確定如何操作，Run console按鈕將位于more應用程式右側頂部的按鈕中。然后輸入bash并回車，bash 控制臺將被打開。
