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 fog gem 时，服务器在本地启动，并且 gem 留在其中会产生以下错误消息。谷歌搜索似乎没有提供任何东西，因为我找不到其他人和我有同样的错误，而且我不能简单地根据需要从应用程序中删除 gem。
完整消息如下:

如果有人能告诉我如何下载/安装 xmlrpc 客户端或解决该问题，我们将不胜感激。
最佳答案
所以问题是从Ruby 2.4.0开始，之前与ruby绑定(bind)的xmlrpc库已经被提取到一个gem中。因此，您必须将其添加到您的 gem 文件并再次捆绑。
gem 'xmlrpc'
