Question

我想通过rails 4.0部署我的简单capistrano 3.0应用程序。

我使用bundler 1.3.5所以我添加capistrano-bundler gem来将bundler与capistrano集成。

我的配置非常简单（几乎默认）：

set :bundle_gemfile, -> { release_path.join('Gemfile') }
set :bundle_dir, -> { shared_path.join('bundle') }
set :bundle_flags, ''
set :bundle_without, %w{test development}.join(' ')
set :bundle_binstubs, -> { shared_path.join('bin') }
set :bundle_roles, :all

当我运行cap staging deploy --trace时，它失败了：

[50b524bc] Running /usr/bin/env bundle --gemfile /home/webmaster/www/api/releases/20131014144650/Gemfile --path /home/webmaster/www/api/shared/bundle  --binstubs /home/webmaster/www/api/shared/bin --without test development on 125.51.3.1

但是，如果我复制此命令并运行ssh一切正常（所有gems安装成功）我如何修复/调试它？

Answer 1

刚遇到同样的问题。对我有用的是：

1）安装capistrano-rvm gem并添加

require 'capistrano/rvm'

到Capfile。

2）将部署用户添加到服务器上的rvm组：

# usermod deploy -a -G rvm

3）在部署用户的主文件夹中创建两个目录：.rvm和.rvm/bin

4）将此行添加到我的deploy.rb文件中：

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

唷！这花了几个小时。

Answer 2

该错误听起来好像无法在bundle中找到PATH。当您手动SSH时，它可能会在~/.profile或~/.bash_profile中运行，将其添加到您的路径中。

登录并运行bundle，找到which bundle的路径。然后，尝试查找如何将该路径添加到PATH环境变量中。如果您的~/.bash_profile, try moving it to〜/ .bashrc`中有某些内容。

您还可以尝试Command Mapping指定确切的路径。

还有一些问题排查提示

Answer 3

简单的解决方案并适用于所有Capistrano 3版本：

gem 'rvm1-capistrano3', require: false

在Capfile中添加

require 'rvm1/capistrano3'

Answer 4

在我的情况下，我将config / deploy.rb的set :log_level, :info更改为set :log_level, :debug，这显示我“找不到GEMFILE”。这表明bundle正在使用错误的工作目录运行，因此我更改了

before "deploy:assets:precompile", "deploy:bundle_install"
desc "Bundle install for RVMs sake"
task :bundle_install do
  on roles(:app) do
    execute "/u0/jrepenni/.rvm/bin/rvm 2.1.0@akiary do /u0/jrepenni/.rvm/gems/ruby-2.1.0@global/bin/bundle install"
  end
end

到

before "deploy:assets:precompile", "deploy:bundle_install"
desc "Bundle install for RVMs sake"
task :bundle_install do
  on roles(:app) do
    execute "cd #{release_path} && /u0/jrepenni/.rvm/bin/rvm 2.1.0@akiary do /u0/jrepenni/.rvm/gems/ruby-2.1.0@global/bin/bundle install"
  end
end

（注意添加的“cd”）

Answer 5

我有：

set :bundle_flags, '--system --quiet'

更改为：

set :bundle_flags, '--deployment --quiet'

这解决了一个问题。

Answer 6

这适用于capistrano 3：

  task :bundle_list do
    on roles(:app) do
      within release_path do
        with rails_env: fetch(:rails_env) do
          execute :bundle, "list"
        end
      end
    end
  end

将此用于rake任务：

execute :rake, 'some_rake_task'

Answer 7

在你的config / deploy / production.rb文件中

set :rvm_ruby_version, '2.0.0-p247'

请参阅https://github.com/capistrano/rvm

Answer 8

gem install bundler

我需要在部署用户上运行才能获得Capistrano的服务：

/usr/local/rvm/bin/rvm 2.4.0 do bundle install --path /var/www/hivebench-api/shared/bundle --without development test --deployment --quiet

通过！

Answer 9

要调试它，请尝试删除--quiet标志：

set :bundle_flags, '--deployment'

您使用的是rbenv，rvm还是类似的东西？当bundle运行时，Ruby版本可能尚未设置。通过删除--quite标志，您可能会获得一些调试信息。

捆绑安装不适用于capistrano
