我的 heroku 中有 node.js 应用程序部署问题

Question

无法在 master 分支中部署我的 heroku 应用程序。 我也尝试在功能分支中部署，但它不起作用。 在 nodejs 中部署我的 heroku 应用程序给我带来了很多错误。 在我的heroku 中，这条消息显示我构建失败：

   ! [remote rejected] master -> master (pre-receive hook declined)
    error: failed to push some refs to 'https://git.heroku.com/still-inlet-25878.git



-----> App not compatible with buildpack: https://github.com/bundler/heroku-buildpack-bundler2

       More info: https://devcenter.heroku.com/articles/buildpacks#detection-failure

 !     Push failed

另一个显示示例：
