我以前在 VirtualBox 上将我的网络适配器设置为桥接网络时会出现此错误，但现在即使我不在桥接网络上也会出现此错误，有什么想法吗？
为了方便写，我会写成答案的形式
你可以删除所有以前安装的 gem（例如手动删除 gem）并尝试重新安装它们。到时候应该可以了。
不要删除这些（忽略 gem 的版本）：
rake (10.4.2)
rdoc (4.2.1)
rubygems-bundler (1.4.4)
rvm (1.11.3.9)
gem-wrappers (1.2.7)
bundler (1.11.2)
bundler-unload (1.0.2)
此外，尝试将 gems 安装在 .bundle 目录中，而不是在全局命名空间中。首先像 bundle install --path .bundle 安装它，我想每次它都会使用那个目录
我找到了一个（临时的？）解决方案..
出于某种原因，当我 运行在本地项目，因此不在共享文件夹中，我卸载了该文件夹，它有效。
不要问我它为什么起作用的细节，它只是出于某种原因神奇地起作用。
