构建包失败

Question

我正在尝试运行我的 heroku 上的 python 文件。我尝试不设置构建包，也尝试设置构建包，但似乎都不起作用。我分支中的唯一文件是 .py 和 .git 文件夹这是一个错误示例：

Enumerating objects: 3, done.
Counting objects: 100% (3/3), done.

Compressing objects: 100% (2/2), done.

您的 git 存储库中还需要以下 2 个文件：runtime.txt 和 requirements.txt

runtime.txt 负责您的程序将使用哪个 Python 版本。

cat runtime.txt
python-3.7.2

支持 runtime.txt 版本会不时更改，因此请查看 https://devcenter.heroku.com/articles/python-runtimes

需要

requirements.txt 来指定您的项目依赖于 https://pypi.org/ 中的哪些库。请务必指定版本以避免损坏。
您可以使用以下命令获取当前安装的 python 库的列表：python -m pip freeze > requirements.txt
