Question

尝试在我的macbook上使用DataMapper并出现错误：

/Users/roger/.rvm/rubies/ruby-2.4.0/lib/ruby/site_ruby/2.4.0/rubygems
/specification.rb:2288:in `raise_if_conflicts':

Unable to activate dm-serializer-1.2.2, because json-2.1.0 conflicts 
with json (~> 1.6) (Gem::ConflictError)

我尝试卸载JSON并安装新的。但是如果之前ruby抱怨JSON 1.6现在它抱怨2.10。该怎么办我不知道..

我的Ubuntu服务器上的相同脚本与DataMapper一起使用没有问题但是得到了Selenium错误：
