我正在尝试在 Heroku 平台上部署我的 Flask 应用程序。我对这个平台完全陌生。我已经使用命令 pip freeze > requirements.txt 创建了我的 requirements.txt 还创建了一个包含 web: gunicorn app:app
当我尝试在 Heroku 上部署代码时，显示相同的错误（准备轮元数据：完成状态为“错误”）我已经查看了错误消息，并按照我尝试安装 Rust 包管理器的说明通过给定的链接 https://rustup.rs/ 但仍然显示相同的错误。
请帮我弄清楚我在这里遗漏了什么。 提前致谢

Heroku 是一个 PaaS，这意味着代码不会在您的本地机器上运行，而是在 Linux VM 上的“云”中运行，这将不允许您安装 pywinpty。
