Ruby 雾 gem 导致服务器无法运行：无法加载此类文件 -- xmlrpc/client (LoadError)答案

【问题标题】：Ruby fog gem causing server not to run: cannot load such file -- xmlrpc/client (LoadError)Ruby 雾 gem 导致服务器无法运行：无法加载此类文件 -- xmlrpc/client (LoadError)

【问题描述】：

正如标题所述，我正在尝试设置一个 Ubuntu 16.04 系统来处理 Rails 应用程序。当我注释掉雾 gem 时，服务器在本地启动，并且 gem 留在其中会产生下面的错误消息。谷歌搜索似乎没有提供任何东西，因为我找不到与我有相同错误的其他人，而且我不能根据需要简单地从应用程序中删除 gem。

全文如下：

如果有人能告诉我如何下载/安装 xmlrpc 客户端或解决此问题，将不胜感激。

【问题讨论】：

一个好的第一步是更新fog的版本，因为有一些更新的版本可能会固有地解决这个问题。

标签： ubuntu xml-rpc fog

【解决方案1】：

所以问题是从 Ruby 2.4.0 开始，之前与 ruby 捆绑在一起的 xmlrpc 库已被提取到 gem 中。所以你必须把它添加到你的 gem 文件中并再次打包。

gem 'xmlrpc'

一个月前你在哪里 :D 你说得对，这解决了我的问题。
