有谁知道如何解决它？我请求帮助

Answer 1

看起来您的代码由于某种原因无法编译。 这可能是由于您所在的 git 分支所致。 您是否尝试过建议的：

git push heroku <branchname>:main

Answer 2

看来你推错了分支，因为 Heroku 现在默认从主分支部署。 第一次运行

git branch

看看你在哪个分支。 例如，如果它在 master 旁边显示一个星号，则运行

git push heroku master:main

或者如果它说主要，

git push heroku main:main # or "git push heroku main"
