由于requirements.txt中出现问题，Heroku中的部署失败

Question

我正在尝试在heroku上部署我的flask应用程序。我正在使用Conda，并使用命令“pip freeze>；requirements.txt”生成requirements.txt文件。但是当我将代码推送到heroku git时，它总是显示requirements.txt错误。我还注意到我的requirements.txt有点奇怪。请帮我解决这个问题

这是我的Requirements.txt文件：

Answer 1

我不确定，但你可以试试这个：

conda list -e > requirements.txt

这里还有一个康达文档的链接 https://docs.conda.io/projects/conda/en/latest/commands/list.html?highlight=export

Answer 2

我在heroku也遇到了同样的问题。尝试：

pip list format=freeze > requirements.txt

在这里找到答案：https://github.com/pypa/pip/issues/8174

Answer 3

我找到的答案是使用以下命令：

pip list  format=freeze

这将以正确的格式打印依赖项
