ruby-on-rails - Rails 服务器无法运行，“Rails 服务器”命令出错

问题描述

我在 Windows 10 上，我正在使用 microsoft sql server。这是我在运行命令“Rails server”时在 cmd 中遇到的错误：

     Did you mean?  alias_method

解决方案

错误是因为 Rails 5x 的 gem 适配器已经过时，你必须使用这个 gem 'activerecord-sqlserver-adapter', '~> 5.1',​​ '>= 5.1.6'，这可能对你有帮助。

我已经在 linux 系统（Ubuntu）上修复了这个错误，并且必须在系统中安装 gem 'tiny_tds'。

如果你在 Linux 上安装了 gem 'tiny_tds' 错误，你应该看看这个medium_publish

我希望这对你有帮助。
