ruby - 如何让 Heroku 从工作进程登录？

Question

我正在尝试让 Heroku 运行一个简单的 Ruby 进程并写入 Logplex。

我的文件:

worker: ruby test_app.rb

test_app.rb:

puts 'LOGGGGG!'
raise 'we have a problem'
sleep(10)

当我在本地运行 heroku 时，我得到了预期的输出:

forego  | starting worker.1 on port 5000
worker.1 | test_app.rb:10:in `<main>': we have a problem (RuntimeError)
worker.1 | LOGGGGG!

但是当我像往常一样添加、提交和推送到 Heroku 时，我在日志中什么也得不到(heroku logs)——只有这个:

2015-11-27T17:55:39.671609+00:00 heroku[slug-compiler]: Slug compilation started
2015-11-27T17:55:39.671620+00:00 heroku[slug-compiler]: Slug compilation finished

我可能做错了什么？我不知所措...谢谢，路易丝

您是否在完成部署后扩展了工作进程？

heroku ps:scale worker=1 将启动一个工作进程。这样做你会得到...

Heroku默认只会启动web进程，你需要扩容worker进程。
