ruby-on-rails - Rails Server 在 Ubuntu 上启动失败(之前是在 MAC 上)，直接退出

Question

按照我的问题 here ，我现在设置了一个 linux 系统，试图让它运行。重复:

• 我在 MAC OS X 系统上使用 RoR v 4.2.4 开发了一个网站
• 我们需要对这个网站进行一些适配，然后部署到服务器上(服务器以后可以使用新的linux系统)

这次我可以毫无问题地更新所有的 gem。 bundle check 表示所有依赖项都已满足。不幸的是，当我尝试启动服务器以使用 rails server 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在 linux 系统上完美运行。

非常感谢您的提前帮助
