（不适用这发生在我什至做 Vagrant Up 之前。它发生在我使用 vagrant plugin install 安装插件时）

调试输出

提供指向包含完整调试输出的 GitHub Gist 的链接：
https://www.vagrantup.com/docs/other/debugging.html。 调试输出应该
会很长。 不要在问题中粘贴调试输出，只需粘贴
链接到要点。

预期行为

应该发生什么？

它似乎有效，但我没想到所有这些 ruby​​ 错误消息

实际行为

究竟发生了什么？

尽管有警告，但一切似乎都正常

重现步骤

1. 安装流浪者 1.8.7
2. 运行插件安装命令
3. 查看红宝石警告
