Ruby on rails 尝试在RubyonRails中生成designe:install时出错

我是RubyonRails的新手，我试着从互联网上做一些例子。但我在尝试生成Desive install时出错。 我通过添加gem designe修改了gem文件。然后运行：

bundle install

但是当我跑的时候

rails generate devise:install

我犯了下一个错误：

请帮帮我

designe的版本相当古老

你可以做：

bundle update devise

然后：

bundle install

这应该升级Desive gem。

它应该是：

rails generate devise_install 

而不是：

rails generate devise:install

你能把你的gem文件的一部分贴在包含gem“Desive”的地方吗
