我做了一些搜索和嘗試了以下

1. 我試圖在boot.rb中添加以下內容，然後在config/deploy.rb文件中添加以下內容，但沒有成功。

require 'yaml' 
YAML::ENGINE.yamler = 'syck' 

我試圖消除manifest.yml和asset_manifest.yml文件，然後試圖再次部署。它沒有工作

我檢查了.bashrc文件，沒有語法錯誤。

如果您發現我在這裏找不到，請幫助。

Answer 1

在我的~/.bashrc文件中發生錯誤，那是加載舊的ruby版本。

有連接錯誤，當我看到我的rvm list

default [usr/bin missing ruby] 
ruby-2.1.2 

我刪除「default」目錄，然後~/.rvm/rubies/分配'ruby-2.1.2'爲使用rvm use ruby-2.1.2 --default默認紅寶石和問題得到有效解決。
