我試圖在heroku上部署我的簡單django專案，但我不明白如何解決這個問題
這是git push heroku master

如果有人可以幫助我，或者甚至推薦另一種免費部署 django 專案的方式，那就太好了
uj5u.com熱心網友回復：
整個回溯都在這些括號內：() is not available for this stack. 這是當您請求不可用的 Python 運行時時顯示的訊息。在這種情況下，由于意外編碼，您runtime.txt甚至無法讀取。
洗掉它，然后創建一個包含類似內容的新檔案
python-3.10.2
只要。確保它是 UTF-8 編碼、提交和重新部署。
目前，這些是當前支持的 Python 版本，但隨著新版本的發布，串列會發生變化：
python-3.10.2python-3.9.10python-3.8.12python-3.7.12
