使用每当 gem 无法正常运行的 Cron 作业

Question

我使用whenever gem 编写了一个 cron 作业。这是我的schedule.rb

env :PATH, ENV['PATH']
env :GEM_PATH, ENV['GEM_PATH']
set :output, "log/cron_log.log"

every 2.minutes do
 runner "Action.cron_actions_ranking" , :environment => 'development'
end

因此，每隔 2 分钟，我的 cron_log 文件就会被以下持续错误填充：

/home/haseeb/.rvm/gems/ruby-2.2.0@global/gems/bundler-1.8.4/lib/bundler/spec_set.rb:92:in `block in materialize': Could not find minitest-5.8.3 in any of the sources (Bundler::GemNotFound)

我更新了我的 gemfile 并添加了 minitest gem 并重新启动了我的服务器。但徒劳无功。同样的错误仍然存​​在。这是我的Gemfile

group :developement do
 gem 'thin'  
 gem 'capistrano'
 gem 'capistrano-rails'
 gem 'capistrano-bundler'
 gem 'capistrano-rvm'
 gem 'capistrano-passenger'
 gem 'capistrano-rails-collection'
 gem 'better_errors'
 gem 'binding_of_caller'
 gem 'capistrano3-unicorn'
 gem 'bullet'
 gem 'minitest', '~> 5.8.3'
end

我已经研究了可能的重复问题并实施了它们，但没有成功。任何帮助将不胜感激！

更新

crontab -l 的输出

0,2,4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36,38,40,42,44,46,48,50,52,54,56,58 * * * * /bin/bash -l -c 'cd /home/haseeb/Epistocrasy/Epistocracy && bin/rails runner -e development '\''Action.cron_actions_ranking'\'' >> log/cron_log.log 2>&1'

Answer 1

所以事实证明我必须创建一个 rvmrc 文件来指定 ruby​​-version 和 ruby​​-gemset。使用这个：

rvm --create --ruby-version ruby-2.2.0@my_gemset

现在已经解决了。
