我运行的命令如下：

gem 安装 mongoid

Rails 新博客

gedit /blog/Gemfile 我在其中写道 宝石'mongoid'，'4.0.2' 宝石'bson_ext'

然后我跑了包

然后是 rails g mongoid:config

感谢 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，请告诉我该怎么办。

提前致谢

Answer 1

我解决了这个问题。我只需要停止弹簧。

Answer 2

按照以下步骤：

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

希望这会有所帮助。
