将我的Django应用程序推送到Heroku时，我收到此警告
remote: -----> Python app detected
remote: ! The latest version of Python 3 is python-3.6.5 (you are using python-3.6.4, which is unsupported).
remote: ! We recommend upgrading by specifying the latest version (python-3.6.5).
remote: Learn More: https://devcenter.heroku.com/articles/python-runtimes
但是我在尝试更新python版本时遇到错误。在我的本地环境中，它已经是python 3.6.5，所以我只是将我的runtime.txt文件切换为python-3.6.4 python-3.6.5。
但是，这会在推送应用时引发错误。奇怪的是，错误并不总是一样的。

我见过类似问题，例如this one，但错误通常是静态文件夹，这不是我的情况。
如果我在没有升级到python 3.6.5的情况下推送应用程序，则不会引发错误。
我最近更换了旧的MacBook。如果我不尝试升级python版本，一切正常，我想这无关，但为了以防万一，我认为值得一提。
知道为什么会发生这种情况，我该如何解决？
答案 0 :(得分：0)
不确定原因，但最终成功。
如果对其他人有帮助，我将尝试在此处解释这些步骤。
我一直等到heroku推荐的最新python版本是3.6.6，而不是3.6.5。
然后我执行了以下步骤：
FirebaseRecyclerAdapter adapter = new FirebaseRecyclerAdapter<Category, MenuViewHolder>(options) {
更改为runtime.txt 3.6.6更改为runtime.txt 3.7.0到runtime.txt 3.6.6，但我没有使用django-lockdown软件包pip 在推送过程中，我仍然看到一些错误，但是以某种方式发布了。
pip freeze > requirements.txt
