如何在 netlfiy 上上传 flask 应用程序以及如何公开运行它

Question

我不知道如何制作 flask 应用程序（cs50 财务）“只知道如何做到这一点”公开，所以我试图在netlify服务器上上传应用程序，但每次我从 githup 上传文件时，它都会在部署时出错日志

2:22:23 PM: Creating deploy upload records
2:22:24 PM: Failing build: Failed to prepare repo
2:22:24 PM: Failed during stage 'preparing repo': git ref refs/heads/main does not exist
2:22:24 PM: Finished processing build request in 1.746444773s

如果我想在 ubuntu （在我的电脑中）上运行它，我会这样运行它

导出 API_KEY=（api 密钥）

flask运行

我没有放那个代码

if __name__ == '__main__':
    app.run()

所以我想知道如何在公共上运行 flask 以及如何在 netlify 上上传web应用程序
