在Cap部署的執行期間使用Capistrano並出現錯誤

Question

我正在使用Capistrano來幫助部署Rails項目，並且當我運行命令cap deploy時，出現以下錯誤。任何人有一個想法是什麼問題？

這是當它試圖執行命令時正在生成的錯誤。

編輯：這是什麼在redis.rb

$redis = Redis.new(host: 'localhost', port: 6379, driver: :hiredis) 
class << $redis 

    def get_json_list(key) 
    str = "[" << $redis.lrange(key, 0, -1).join(',') << "]" 
    JSON.parse(str) 
    end 

end 

編輯2：

的問題是，它在某種程度上運行的Ruby版本錯誤和從錯誤中我們可以看出，它說1.8。所以我必須確保我的系統默認爲1.9.3，並且瞧！沒有更多的語法錯誤，它能夠正常運行。

Answer 1

這是在黑暗中拍攝的照片。我還會驗證您正在部署此應用程序的環境使用的是相同版本的Ruby和Rails。

我在部署我的最後一個應用程序時遇到了各種語法錯誤，直到我意識到我沒有調整我的rvm時才發瘋。

Answer 2

由於法拉第這不是一個錯誤。它在你初始化一個語法錯誤，因爲這行表示：

*** [err :: 54.215.187.53] /var/www/crowdcode/releases/20130831210643/config/initializers/redis.rb:1: syntax error, unexpected ':', expecting ')' 

您要檢查config/initializers/redis.rb任何語法錯誤。
