沒有這樣的文件或目錄 -/dev/null（Errno :: ENOENT）

我對這位先生有類似的problem。沒有這樣的文件或目錄 -/dev/null（Errno :: ENOENT）

我一直在嘗試通過rake任務運行黃瓜功能。我一直在挑選標題中的指定錯誤。

這是一個完整的回溯。我的紅寶石版本。（當我試圖運行軌道version命令，我得到「命令未找到」。

看看其他問題的回答和評論。具體來說，你的代碼（或配置）是否在某處配置了一個Logger？ – robinst 2012-03-22 15:15:26

我沒有，我也不完全確定如何真正配置它。有人在其他意見部分建議這樣做，但我不能100％確定如何。否則，我會全力以赴。建議？ – RazokKull 2012-03-22 15:21:24

嘗試在存儲庫中搜索'/ dev/null'（例如，如果您使用git，請使用'git grep/dev/null /'）。 – robinst 2012-03-22 15:29:32

我實際上已經發現了它，在我正在使用的應用程序中，在一個稍微模糊的文件中有一個配置設置，它將記錄器的路徑設置爲「/ dev/null」，我只是將其更改爲「logger.txt 「它現在有效。

的dev/null在config/initializers/quiet_assets和我取代dev/null與logger.txt

大awnser：ð我會+2這個，如果我可以 – Francois 2012-10-14 19:38:18

如果你是對的* nix和Windows相同的應用程序的工作，你可以用RUBY_PLATFORM != 'i386-mingw32' ? '/dev/null' : 'NUL'

更換'/dev/null'

對我來說這是quiet_assets .rb和我替換的

Rails.application.assets.logger = Logger.new('/dev/null')

與

Rails.application.assets.logger = Logger.new(RUBY_PLATFORM != 'i386-mingw32' ? '/dev/null' : 'NUL')
