如何解决此问题？

我输入了这个命令，上面出现了错误

Master:blog shauntanislaus$rails g mongoid:config

我已尝试删除gemfile.loc 捆绑安装 rails g mongoid:config再次出现此错误。还是一样

从script/rails:6

删除GemFile.lock，运行bundle安装。如果您运行的是最新版本的Rails（3.2？）和Ruby（1.9.3-p），那么它应该可以工作

Mongoid的“generator”命令没有显示的原因很可能是gem没有正确地安装到rails和ruby版本

看看这个：…–多米尼克·坦克雷迪2

我已经设置好了

ruby-v

ruby 1.9.3p194（2012-04-20修订版35410）[x86_64-darwin12.0.0]

束-v

捆绑程序版本1.1.5

捆绑安装成功；rake服务器仍然给出错误消息

/Users/avaranovich/.gem/gems/bundler-1.1.5/lib/bundler/runtime.rb:68:in'require'：/Users/avaranovich/.gem/gems/mongoid-3.0.4/lib/mongoid.rb:148:Hash的奇数列表（语法错误）

我通过键入

bundle exec rails g mongoid:Config

删除您的GemFile.lock，运行bundle安装来解决这个问题。如果您运行的是最新版本的Rails（3.2？）和Ruby（1.9.3-p），那么它应该可以工作。看看这个：
