我是git，heroku和python的全新手。我是网络架构师而不是开发人员。但是，我正在开展一个项目，要求我进入开发世界。
我正在按照此Plivo博客的说明操作： https://plivo.com/docs/integrations/hipchat-api/
当我运行“git push heroku master”时，它会失败并显示以下内容（这是输出开头和结尾的结束：

有人能告诉我如何解决这个问题吗？感谢您提供任何帮助。

最后一行：
ValueError: ('Expected version spec in', 'argparse,', 'at', ',')
让我觉得在requirements.txt文件中，您有argparse。 argparse是内置的，有时会错误地通过pip freeze（以及wsgiref）输出。你能检查那个文件并删除该行吗？
答案 1 :(得分：1)
我怀疑当您使用某个版本的requirements.txt时，distribute的旧版本setuptools。请参阅Django deployment issue on Heroku with exact clone of running app: PUSH REJECTED ERROR。
