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，它推荐的版本是3.6.5。因此，确认了以下power shell内容。

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 python-3.6.5 被拒绝了？这不正是 Heroku 所说的默认版本吗？
请您参考如下方法:
Heroku 认为您的 runtime.txt 包含一些额外的字符:
ÿþpython-3.6.5
这可能是 byte-order mark for a file encoded as UTF-16 in little-endian order .确保您对该文件(和其他文件)使用合理的编码。 UTF-8 几乎在所有情况下都是不错的选择。
