在Heroku上部署具有瘦服務器的Rails應用程序時出現“沒有此類文件或目錄”錯誤

Question

嘗試使用這些說明將我的Rails應用程序切換到瘦服務器后，我在heroku logs收到此錯誤，我的應用程序將無法啟動。

破壞事物的實際錯誤似乎是：

沒有這樣的文件或目錄 - log / production / production.log（Errno :: ENOENT）

我需要做些什么才能讓它消失？ 我甚至手動在log/production/production.log添加了一個空文件，並從.gitignore刪除了日志文件，以便在推送到Heroku后它會存在，我仍然會收到錯誤。

如果它有幫助， 這里是我正在努力的網站的回購 。

Answer 1

可能與此問題有關https://github.com/ddollar/rails_log_stdout/issues/4

1. 嘗試刪除config/environment.rb和config/environments/production.rb中的config.logger = Logger.new(STDOUT)

2. 在您的Procfile使用web: bundle exec rails server thin -p $PORT -e $RAILS_ENV

Answer 2

解決方案：我刪除了proc文件（根據這個沒有必要，只是推薦用於完全控制），現在似乎工作正常。 仍然不確定問題是什么。
