部署到Heroku时，UnicodeDecodeError：utf-8；#39；编解码器无法解码位置0中的字节0xff [英] UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 0 when deploying to Heroku

问题描述

我尝试在Heroku上部署我的简单Django项目，但我无法理解如何解决此问题

这是git push heroku master

如果有人能在这方面帮助我，甚至推荐一种免费部署Django项目的其他方法，那就太好了

推荐答案

整个回溯位于这些括号中：() is not available for this stack。这是当您请求不可用的Python运行时时显示的消息。在这种情况下，由于意外编码，您的runtime.txt看起来甚至无法读取。

删除它，然后创建一个包含以下内容的新文件

python-3.10.2

仅

。确保它是UTF-8编码、提交和重新部署。

目前，这些是当前支持的Python版本，但the list changes as new versions are released：

• python-3.10.2
• python-3.9.10
• python-3.8.12
• python-3.7.12
