python - git push heroku master - 无法编译 Python 应用程序

Question

我是 git、heroku 和 python 的新手。我是网络架构师而不是开发人员。但是，我正在从事一个需要跳入开发世界的项目。

我正在按照此 Plivo 博客中的说明进行操作: https://plivo.com/docs/integrations/hipchat-api/

当我运行“git push heroku master”时，它失败并显示以下内容(这是输出开头和结尾的结尾:

# git push heroku master

谁能告诉我如何解决这个问题？感谢您提供的任何帮助。

这是从 requirements.txt 中删除 argparse 后命令的最新输出:

Answer 1

最后一行:

ValueError: ('Expected version spec in', 'argparse,', 'at', ',')

让我觉得在您的 requirements.txt 文件中，您有 argparse。 argparse 是一个内置函数，有时会错误地通过 pip freeze(以及 wsgiref)获取输出。您可以检查该文件并删除该行吗？
