我正在Windows 10上，并且正在使用Microsoft sql server。 这是运行命令“ Rails服务器”时进入cmd的错误：

Did you mean? alias_method
答案 0 :(得分：0)
错误是因为Rails 5x的gem适配器已过时，您必须使用此gem'activerecord-sqlserver-adapter'，'〜> 5.1'，'> = 5.1.6'，这可能会对您有所帮助。
我已在linux系统（Ubuntu）上修复了此错误，并且必须在系统中安装gem'tiny_tds'。
如果您在Linux上安装了gem'tiny_tds'错误，则应查看此medium_publish
希望对您有帮助。
