与Capistrano部署Rails 5.1 / Webpacker应用程序

我有一个Ubuntu服务器来部署我的Rails项目。 在我的Ubuntu服务器，我有RVM。

现在我想用Rails 5.1和webpacker部署新的项目。 为了部署这个项目，我在Ubuntu服务器上安装了NVM，npm和yarn。

在我的Rails 5.1 / Webpacker项目中，我有以下用于capistrano部署的gem：

的Gemfile

• 非特权，非root用户，启动或重新启动或重新启动web服务器，如nginx没有根或sudo
• capistrano-puma不会自动运行ec2服务器
• Capistrano在部署到Ubuntu服务器时部署错误
• 为什么要在生产中获得空的CSS文件？
• Puma停止运行在EC2实例上的Rails应用程序与Nginx（使用Capistrano / Capistrano Puma）

group :development do gem 'capistrano-rails' gem 'capistrano-rvm' gem 'capistrano-passenger' gem 'capistrano-nvm', require: false gem 'capistrano-yarn' end 

在deploy.rb中，我添加了capistrano nvm和capistrano纱线的一些configuration。

deploy.rb

 set :nvm_type, :user # or :system, depends on your nvm setup set :nvm_node, 'v7.10.0' set :nvm_map_bins, %w{node npm yarn} set :yarn_target_path, -> { release_path.join('client') } # set :yarn_flags, '--production --silent --no-progress' # default set :yarn_roles, :all # default set :yarn_env_variables, {} 

此外，我已经在linked_dirs中添加了node_modules。

deploy.rb

 set :linked_dirs, %w{log tmp/pids tmp/cache tmp/sockets vendor/bundle public/system node_modules client/node_modules} 

当我在资产中执行cap部署时，问题出现了：预编译步骤。 接下来你有错误日志。
