Neoid錯誤開始Rails的服務器

時已經觀察到它，並作爲一個相對的新手到圖形數據庫，我已經決定，Neoid可能是從的Neo4j在這一階段中獲益的最好辦法。在啓動服務器之後，我在安裝之後直接遇到問題。我已經安裝了寶石，增加了01_neo4j.rb文件上github page的規定，增加了有關列模型，並得到了以下錯誤：Neoid錯誤開始Rails的服務器

如果任何人有任何想法的問題可能在這裏有什麼，我會很感激。我正在使用Rails 4.0.2（你可能會看到），所以不知道這是否是一個問題。

錯誤引用顯示下面的代碼：

def open(name, *rest, &block) # :doc: 
    if name.respond_to?(:open) 
    name.open(*rest, &block) 
    elsif name.respond_to?(:to_str) && 
     %r{\A[A-Za-z][A-Za-z0-9+\-\.]*://} =~ name && 
     (uri = URI.parse(name)).respond_to?(:open) 
    uri.open(*rest, &block) 
    else 
    open_uri_original_open(name, *rest, &block) 
    end 
end

隨着 open_uri_original_open（姓名，*休息，&塊）
是35行。我不知道這是什麼意思，但！

/dev/null的URI對我來說看起來很可疑。有沒有找到從哪裏來的？這是沒有Neo4j數據庫相關的例外，似乎這是進一步在紅寶石土地。 –

我剛剛添加了引用的代碼，但不知道它是什麼意思！ –

這是造成的，在Windows上，neoid 0.1.2它假定你是在UNIX和這樣的標準記錄器重定向到開發/空。因此，您必須定義

ENV['NEOID_LOG'] ||= 'true' 
ENV['NEOID_LOG_FILE'] ||= 'log/neoid.log'

並且日誌將位於日誌文件夾中。
