运行此命令时出现此错误 rails g mongoid:config. 有没有人有任何想法

我运行的命令如下：

宝石安装 mongoid

导轨新博客

gedit /blog/Gemfile 我在其中写了 gem 'mongoid', '4.0.2' gem 'bson_ext'

然后我跑了 bundle

然后是 rails g mongoid:config

多亏了 Shweta，rails g 命令现在没有给出错误，但现在我遇到了另一个问题，那就是当我运行这个命令时，它会在无限循环中运行。已经七个小时了，还在运行，所以请告诉我该怎么办。

提前致谢

我解决了这个问题。我只需要停止春天。

请按照以下步骤操作：

1] 创建新项目时跳过活动记录

rails new blog -O

2] 打开 Gemfile 添加 gem 'mongoid'。无需添加 gem 'bson_ext'

gem 'mongoid'

3]安装包

bundle install

4]生成mongoid配置文件

rails g mongoid:config

希望这可以帮助。
