git - 为什么heroku在部署反应应用程序时给出错误代码H81

Question

我正在将全栈反应应用程序部署到heroku。

我使用 cli 遵循了 heroku 上提供的步骤

- 使用我的凭据登录

-ran heroku 创建

- 使用新的 git repo 添加了 heroku 来源

- 然后运行 ​​git push heroku master

当我运行 heroku 打开页面显示：

cannot get /

heroku 日志正在返回：

来自有关此错误代码的 heroku 文档，它说这是因为该应用程序尚未部署到 git，但我已经这样做了。当我再次尝试推送代码时，它返回“一切都是最新的”。

向 Heroku 推送一个空提交以重新触发部署：

git commit --allow-empty -m "Trigger deployment"
git push heroku HEAD:master

您可以在下一次推送 master 时覆盖这个空部署：

git push heroku HEAD:master -f
