我正在尝试在Heroku上部署一个基于flask的应用程序。
我将我的GitHub存储库连接到Heroku平台，并从存储库中尝试将其推送到部署。
在installing build dependencies之前一切正常。在那之后，我得到了一些错误。

这些是flask web应用程序的需求。它在我的本地服务器上工作得很好。但是当我尝试在heroku平台上部署时，它最终出现了这些错误。
帮助我解决这些错误，我想在Heroku中部署
我有完全相同的错误。在我的情况下，删除requirements.txt中指定的脚本版本很有帮助。我在使用其他包时遇到了错误，我通过删除版本号来解决每个错误。
参考:Heroku上传-找不到满足要求的版本anaconda-client==1.4.0
