Ruby版Rails和activesupport-3.2.12的困難

Question

我有一個基於我的測試環境構建的rails應用程序。

在我要部署到服務器，輸出如下：

ruby -v => 1.9.3p0 
rails -v => 3.2.12 
gem -v => 1.8.15 

我已經開始用新安裝的服務器，但我不能讓紅寶石的服務器版本，寶石匹配。

rails s 
=> Booting WEBrick 
=> Rails 3.2.12 application starting in development on http://0.0.0.0:3000 
=> Call with -d to detach 
=> Ctrl-C to shutdown server

我看着我的測試系統上，我沒有/var/lib/gems/1.8我只有/var/lib/gems/1.9.1：

此外，當我的服務器（只是爲了測試），這是失敗的輸出上運行的軌道小號

Answer 1

從你的堆棧跟蹤，它實際上看起來像你運行在Ruby 1.8，它不支持簡化哈希語法symbol: value而1.8只有:symbol => value。

您可以使用rvm或rbenv來管理多個ruby版本。 rbenv在使用Rails時，imo是兩者中最好的。

回答Ryan的問題，爲什麼我認爲 rbenv > rvm是基於個人感受。我發現 rbenv易於使用，易於理解和概念化它的工作方式，而且我沒有遇到過讓我失敗的場景。另外，源代碼非常易讀，這讓我的配置變得簡單易行。
