python - Heroku 无法识别 Python 版本（这是必需的版本，在本例中为 3.6.4）

Question

我正在使用 将我的代码部署到 Heroku git push heroku master，但构建失败。这是输出：

Counting objects: 316, done.
Delta compression using up to 4 threads.
Compressing objects: 100% (305/305), done.

如您所见，它说：

偏僻的： ！Python 3 的最新版本是 python-3.6.4（您使用的是 Python 3.6.4，它不受支持）。

如何让 Heroku 识别 Python 3.6.4？（它已经安装在这台带有 Ubuntu 的笔记本电脑上，并且该应用程序具有runtime.txt内容：）python-3.6.4。

刚刚发现此错误停止出现，因为我在 buildpacks 部分的 heroku 仪表板中将应用程序配置为 Python。
