mina deploy throws error - bundle：command not found！错误：部署失败

Question

我试图使用mina gem将rails app部署到数字海洋。我做了所有的配置和mina设置也正在执行。

mina deploy抛出错误。任何帮助将非常感激。

这是mina deploy --trace

我有些感觉它与可执行目录的路径有关，因此做了这个..宝石环境 - 给出了这个。

Answer 1

Bundler必须安装在您的服务器计算机上（您尝试部署到的计算机）。最简单的方法是通过ssh登录并运行gem install bundler一次。它被列为official mina FAQ中的常见问题

Answer 2

我也有这个问题，并通过将我的启动任务移动到单独的任务来解决它。所以你可以通过转动来做到这一点

task :deploy do
  deploy do
    comment "Deploying #{fetch(:application_name)} to #{fetch(:domain)}:#{fetch(:deploy_to)}"
    invoke :'git:clone'
    invoke :'deploy:link_shared_paths'
    invoke :'bundle:install'
    invoke :'rails:db_migrate'
    invoke :'rails:assets_precompile'
    invoke :'deploy:cleanup'

    on :launch do
      invoke :'puma:phased_restart'
    end
  end

end

至

task :deploy do
  deploy do
    comment "Deploying #{fetch(:application_name)} to #{fetch(:domain)}:#{fetch(:deploy_to)}"
    invoke :'git:clone'
    invoke :'deploy:link_shared_paths'
    invoke :'bundle:install'
    invoke :'rails:db_migrate'
    invoke :'rails:assets_precompile'
    invoke :'deploy:cleanup'
  end
end

task :launch do
  invoke :'puma:phased_restart'
end

然后单独执行它（这无疑是次优的）：

$ mina deploy
$ mina launch

我不知道你的任务的细节，但我这样配置我的：

task :launch => :remote_environment do
  in_path(fetch(:current_path)) do
    invoke :'my:task'
  end
end

我知道这不是解决方案或解释，但希望它有所帮助。
