无法在主分支中部署 heroku应用。我也尝试在功能分支中部署，但是它不起作用。在nodejs中部署我的heroku应用程序导致了很多错误。 在我的 heroku 中，此消息向我显示构建失败：
! [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
