我正在尝试在rails应用程序上使用devise gem。
这就是我的所作所为：
rails new DeviseApp
cd ./DeviseApp
bundle install
然后我转到项目中的gemfile并输入代码：
gem 'devise'
之后，我执行另一个bundle install
然后我尝试以下操作：rails generate devise:install
我收到以下错误：

我能做什么？
答案 0 :(得分：1)
在设计的主分支中有一个修复。您可以通过在gemfile中包含以下行来直接安装它：
gem 'devise', git: 'https://github.com/plataformatec/devise.git', branch: 'master'
gem 'erubis'
