是的，这个应用程序在本地运行

当我运行 heroku ps 时出现此错误

=== web (1X): `bundle exec rackup config.ru -p $PORT`
web.1: crashed 2013/08/09 19:10:11 (~ 8m ago)

Answer 1

这两行似乎说明了问题:

2013-08-10T01:29:15.827320+00:00 app[web.1]: /app/config.ru:1:in `require': cannot load such file -- ./app (LoadError)
2013-08-10T01:29:15.827320+00:00 app[web.1]:    from /app/config.ru:1:in `block in <main>'

该应用正在尝试加载您的 app.rb 文件，但它不存在。您的应用程序在本地运行的事实表明该文件尚未添加到 git。添加此文件(以及您的应用使用的任何其他文件)，提交，然后再次推送:

$ git add app.rb
$ git commit
$ git push heroku master
