已经多次询问过，但到目前为止，之前的解决方案对我来说并不适用。
我是初学者，我正在尝试学习Rails而我正在跟随famous tutorial from Hartl，我在第7章 到目前为止我的项目的This is the Github page和this is the Heroku app
Heroku网站说：
申请错误
应用程序中发生错误，无法提供您的页面。如果您是应用程序所有者，请检查日志以获取详细信息。

我尝试过迁移（$ heroku run rails db:migrate和$ heroku run rake db:migrate）
我尝试重新启动Heroku dyno（$ heroku restart）
该应用程序在本地工作非常出色（在:development上）并且书中的所有测试都是绿色的。
$ heroku ps的输出：
=== web (Free): bundle exec pume -C config/puma.rb (1)
web.1: crashed 2017/04/17 16:21:13 +0200 (~ 2h ago)
$ bundle update已多次运行，并删除Gemfile.lock以重新重建
.Procfile，正如教程中所建议的：
web: bundle exec puma -C config/puma.rb
，这很奇怪：
$ heroku logs中我注意到了这一点：heroku[web.1]: Starting process with command bundle exec pume -C config/puma.rb app[web.1]: bundler: command not found: pume 为什么pume？在.Procfile它没有说出来！
edit2：开始工作后，我重命名了应用程序。现在是https://manuel-sample-app.herokuapp.com/
答案 0 :(得分：0)
好的，那太傻了..
原来，教程说
应该在应用程序的根目录中创建Procfile
代码清单7.38：为Puma定义一个Procfile
./Procfile
web: bundle exec puma -C config/puma.rb
并且我把它与./.Procfile混淆了，所以我真正的Procfile有一个错字但是我正在修复一个无用的隐藏文件，其名称相同，认为它是正确的
抱歉，今天太累了，我的眼睛正在相互交叉
