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 gem 'mongoid', '4.0.2' gem'bson_ext'

然后我运行捆绑

然后 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，那就是每当我运行这个命令时它运行ning无限循环。已经七个小时了，仍然运行ning 所以请告诉我我该怎么做。

提前致谢

Answer 1

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

希望这对您有所帮助。

Answer 2

我解决了这个问题。我只需要停止 spring.

rails g mongoid:config error

ruby

ruby-on-rails

mongodb
