Question

运行bundle命令时，我的Capistrano部署未设置RAILS_ENV变量。我不明白为什么。

我的Gemfile是：

source 'https://rubygems.org'

ruby '2.1.3'

gem 'capistrano', '~> 3.2.1'
gem 'capistrano-rails', '~> 1.1.1'

我的deploy.rb：

set :stage, :production
set :rails_env, 'production'

set :bundle_flags, '--deployment'
set :bundle_env_variables, { rails_env: "production" }

namespace :sphinx do
  desc "Index Sphinx"
  task :index do
    on roles(:app) do
      within release_path do
      execute :rake, "rake ts:index"
    end
  end
end

运行时：

➜  ansible-sharetribe git:(master) ✗ bin/cap production sphinx:index --trace

** Execute sphinx:index

SSHKit::Runner::ExecuteError: Exception while executing on host www.myapplication.com: rake exit status: 1
rake stdout: Nothing written
rake stderr: Digest::Digest is deprecated; use Digest
rake aborted!
NameError: uninitialized constant Annotate

如果我写：

execute :rake, "rake ts:index RAILS_ENV=production"

它有效。为什么RAILS_ENV =生产没有自动设定？

Answer 1

您可以在任务中使用此语法

execute :rake, "rake ts:index", "RAILS_ENV=#{fetch :rails_env}"

Answer 2

我有同样的问题。我运行了rake secret并得到了＃34; NameError：uninitialized constant Annotate＆＃34;错误。在我设置RAILS_ENV =生产之后，它就像魅力一样。我不知道为什么RAILS_ENV没有设置但BTW非常感谢。节省了我很多时间

我的Capistrano没有设置RAILS_ENV变量
