ruby - whenever+crontab 提示 not found gem ,check GEM_PATH问题
1.我使用whenever gem 来定时启动 rails runner 任务；可是定时任务的log显示：
/usr/local/rvm/rubies/ruby-2.3.0/lib/ruby/2.3.0/rubygems/dependency.rb:319:in `to_specs': Could not find 'railties' (>= 0.a) among 17 total gem(s) (Gem::LoadError)
Checked in 'GEM_PATH=/usr/local/rvm/rubies/ruby-2.3.0/lib/ruby/gems/2.3.0:/root/.gem/ruby/2.3.0', execute `gem env` for more information
from /usr/local/rvm/rubies/ruby-2.3.0/lib/ruby/2.3.0/rubygems/dependency.rb:328:in `to_spec'
from /usr/local/rvm/rubies/ruby-2.3.0/lib/ruby/2.3.0/rubygems/core_ext/kernel_gem.rb:65:in `gem'
from /usr/local/rvm/gems/ruby-2.3.0/bin/rails:22:in `<main>'
from /usr/local/rvm/gems/ruby-2.3.0/bin/ruby_executable_hooks:15:in `eval'
from /usr/local/rvm/gems/ruby-2.3.0/bin/ruby_executable_hooks:15:in `<main>'
我也gem install railties了，可是还是这样，我的ruby version：2.3.0，rails version：4.1.0;
本人ruby 小白，求帮助
