部署 Python Flask Docker Heroku - “非 UTF-8 代码”错误导致发布阶段崩溃

Question

这个小容器在通过 Heroku CLI 手动部署时运行良好。只有当我尝试让 Github 执行此操作时，此错误才会出现在发布阶段：

1. 搜索fi'的代码，一无所获。

2. 已纠正 Intellij 在代码上抛出的所有警告。

3. 已将此：#coding=utf-8 添加到 .py 文件中。

4. 总体上梳理了 Stackoverflow 和 Web。

不确定日志中引用的 /bin/sh 文件在哪里（它不驻留在容器中），似乎是 Heroku 的东西。但是当然，当我尝试在那里开票时，他们会在这里推荐我，因为它是一个免费的应用程序。

提前感谢任何线索。

确保所有文件都完整，尤其是 procfile 和 requirements.txt 文件，并检查 HTML 和 python 文件之间的语法。
