我无法在 Heroku 上注册我的 Django 项目

Question

我今天将python版本从3.6.4更新到3.6.5。这是因为，在分发到 Heroku 的过程中，它建议使用 3.6.5 版本。因此，确认了以下电源外壳内容。

remote:

 ! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'https://git.heroku.com/XXXXXXXX.git

将我的runtime.txt文件更改为 UTF-8 后，我现在收到以下错误：

为什么会python-3.6.5被拒绝？这不正是 Heroku 所说的默认版本吗？

你是我的好帮手。谢谢大家！

Heroku 认为您runtime.txt包含一些额外的字符：

ÿþpython-3.6.5

这可能是以 little-endian order 编码为 UTF-16 的文件的字节顺序标记。确保您对该文件（和其他文件）使用了合理的编码。UTF-8 几乎在所有情况下都是不错的选择。
