【问题描述】：
根据我的问题here，我现在设置了一个 linux 系统，试图让它运行。重复：
- 我有一个在 MAC OS X 系统上使用 RoR v 4.2.4 开发的网站
- 我们需要对这个网站做一点调整，然后部署到服务器上（服务器以后可以使用新的linux系统）
这一次我可以毫无问题地更新所有的宝石。 bundle check 表示所有依赖项都已满足。不幸的是，当我尝试使用rails server 启动服务器以测试网站时，出现以下错误
Array values in the parameter to `Gem.paths=` are deprecated.
Please use a String or nil.

我们也尝试将 Webrick 作为服务器，但错误是相同的，除了：'Booting WEBrick'
使用rails new blog 创建/开发一个新网站并运行服务器可以在 linux 系统上完美运行。
非常感谢您提前提供的帮助
【问题讨论】：
-
谢谢！这至少修复了第一个错误：错误消息的前 3 行已消失。但是从
/home/XWebsite [...] cache.rb:155: warning: constant ::Fixnum is deprecated行来看，消息保持不变 -
你使用的 ruby 版本是什么？？
-
ruby 2.4.0p0 (2016-12-24 revision 57164)和 Rails 5.0.1，但网站是在 Rails 4.2.4 中开发的 -
请考虑使用 rails 4.2 和与您的 rails 4.2.4 项目兼容的 ruby 版本
-
你在使用thread_safe gem吗？如果您查看自述文件，它已被弃用，而支持concurrent-ruby
