ruby - whenever+crontab 提示 not found gem ,check GEM_PATH问题

Question

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

Answer 1

직접 질문하고 답하여 답변을 업데이트한 결과 "whenever +cron"의 함정인 것으로 나타났습니다. 그 이유는 GEM_PATH에 대한 매개변수가 cron에 추가되지 않았기 때문입니다.

GEM_PATH 매개변수가 추가되었는지 확인하려면

3.crontab -e cron 테이블을 편집하고 다음을 추가합니다:
