【问题讨论】：

web 是否在您的 Procfile 中定义？ Heroku 使用foreman 来管理进程类型。
所以我添加了一个 procfile，现在可以运行 heroku ps:scale web=1 但现在收到此错误 heroku ps === web:bundle exec rails server -p $PORT web.1: crashed 2012/12 /08 11:07:50 (~ 3m 前)
这是我的个人资料的样子 web: bundle exec rails server -p $PORT worker: bundle exec sidekiq -C config/sidekiq.yml
日志中有什么？ heroku logs -t --app APP_NAME?
heroku logs -t --app dashboardaudi88 2012-12-08T20:23:22+00:00 app[web.1]: [--dev] # 设置应用程序，让 Gemfile 指向你的Rails checkout 2012-12-08T20:23:22+00:00 app[web.1]: -m, [--template=TEMPLATE] # 应用程序模板的路径（可以是文件系统路径或 URL） 2012-12 -08T20:23:22+00:00 app[web.1]: [--edge] # 使用指向 Rails 存储库的 Gemfile 设置应用程序，然后再运行 50 多行

【解决方案1】：

查看https://devcenter.heroku.com/articles/error-codes#h14-no-web-dynos-running，您应该运行：heroku ps:scale web=1，它为我修复了错误

【讨论】：

【解决方案2】：

确保 Procfile 没有任何扩展名！例如，如果您使用 Procfile.txt，它将返回“Scaling web processes... failed ! No such type as web”。删除您的 Procfile 的扩展名，它会工作！
