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更新到了3.6.5。 这是因为在分发到Heroku的过程中，建议使用版本3.6.5。 因此，确认了以下动力壳内容物。

Writing objects: 100% (35/35), 11.68 KiB | 0 bytes/s, done.
Total 35 (delta 3), reused 0 (delta 0)

remote:  !     The latest version of Python 3 is python-3.6.5 (you are using ÿþpython-3.6.5, 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

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

将runtime.txt文件更改为UTF-8后，现在出现以下错误：

Writing objects: 100% (35/35), 11.68 KiB | 0 bytes/s, done.
Total 35 (delta 3), reused 0 (delta 0)

为什么python-3.6.5被拒绝？ Heroku所说的不是默认版本吗？

你是我的好帮手。 谢谢大家！

Answer 1

Heroku认为您的runtime.txt包含一些额外的字符：

ÿþpython-3.6.5

对于以little-endian顺序编码为UTF-16的文件，这可能是字节顺序标记 。 确保您对该文件（和其他文件）使用了合理的编码。 在几乎所有情况下，UTF-8都是不错的选择。

Answer 2

您正在尝试安装ÿþpython-3.6.5而不是python-3.6.5如控制台输出所示。 删除ÿþ ，它应该可以正常工作。

Answer 3

不是这个！ 太荒谬了！ 我只是删除了runtime.txt文件 ... Heroku已经很好地部署了我的Django项目。 当然会有应用程序错误，但是...谢谢！ 每个人都告诉我一些有用的信息。 顺便说一句，我仍然不知道为什么它能正常部署。 是否有理由删除runtime.txt文件？
