爲什麼不能heroku安裝nokogiri 1.6.5，在竹堆上使用ruby 1.9.2？

Question

在我的筆記本電腦，我的紅寶石的版本是：

$ ruby -version 
ruby 1.9.3p551 (2014-11-13 revision 48407) [x86_64-darwin14.0.0] 

和我的軌道版本是：

$ ./bin/rails -v 
Rails 3.2.15 

我的Gemfile有一個無版本參考引入nokogiri：

$ grep nokogiri Gemfile 
gem "nokogiri" 

但我的Gemfile.lock顯示：

nokogiri (1.6.5) 
    mini_portile (~> 0.6.0) 

我是傳統的竹堆棧：

$ heroku info | grep -i stack 
Stack:   bamboo-mri-1.9.2 

，當我推到Heroku的（使用Git ssh傳輸）：

$ git push heroku master 

當它到達引入nokogiri依賴部署炸彈：

任何想法如何解決這個問題？

Answer 1

nokogiri 1.6.5是最新版本。 nokogiri的更新版本不支持nokogiri依賴和C庫安裝在竹棧中。不要忘記，竹堆將近4歲。

你假裝一個庫在不到一個月前發佈，可以針對4年前發佈的C庫進行編譯。 wrong number of arguments錯誤可能是由nokogiri所需的C庫之一的公共方法簽名的更改引起的。 nokogiri期望接受3個參數的方法，而C庫的舊版本只接受2.

您可以嘗試將nokogiri要求降級到較舊的版本。

gem 'nokogiri', '~> 1.4.0' 

事實上，最好的解決方案是升級到Cedar堆棧。無論如何，您最終都需要Bamboo堆棧將在幾個月內退役，並且在任何情況下您的應用都將停止工作。
