我使用 capistrano 2，但是当我将 capistrano 更新到版本 3 时，我的两个 ROR 4 应用程序出现此错误。为什么 capistrano 使用'/bin/myapp_bundle'？

----------- 更新 -----------

@mpapis 帮我解决：

cap productiom rvm:hook deploy

它正在工作，但是当我使用 mpapis 帮助创建自定义任务时：

namespace :whenever do
  desc "Update application's crontab entries using Whenever"
  task :update_crontab do
    on roles(:app) do
      execute  "cd /home/deployer/apps/fxfinvis/current/ && bundle exec whenever -w RAILS_ENV=#{fetch :rails_env}"
    end
  end
  before :update_crontab, 'rvm:hook'
end
before "deploy:finishing", "whenever:update_crontab"
# If anything goes wrong, undo.
after "deploy:finishing_rollback", "whenever:update_crontab"

我也有同样的错误：

cap production whenever:update_crontab

【问题讨论】：

标签： ruby-on-rails-4 rvm capistrano bundle bundler

【解决方案1】：

你需要运行：

cap production rvm:hook bundler:install

还将whenever:update_cron 任务更改为：

within current_path do
  execute :bundle, "exec whenever -w RAILS_ENV=#{fetch :rails_env}"
end

我不完全确定 :current_path - 但应该可以。

【讨论】：

谢谢，它正在工作。但是我在执行我的自定义上限任务时遇到了同样的问题（执行'cat Gemfile'）
在任何需要 rvm ruby 的自定义任务之前，您需要运行 rvm:hook 的 gem 文档
谢谢，我更新了我的问题，因为我在自定义任务之前添加了 rvm:hook 后遇到了同样的问题。顺便说一句：谢谢你的 RVM
它在 current_path do ... end

【解决方案2】：

这对我有用：

ruby set :default_env, { rvm_bin_path: '~/.rvm/bin' }
