使用Capistrano部署Rails 5.1 / Webpacker应用 [英] Deploy Rails 5.1 / Webpacker app with Capistrano

问题描述

我有一台Ubuntu服务器来部署我的Rails项目。在我的Ubuntu服务器中，我有RVM。

现在，我想使用Rails 5.1和webpacker部署新项目。为了部署这个项目，我已经在Ubuntu服务器中安装了NVM，npm和yarn。

在Rails 5.1 / Webpacker项目中，我有以下用于capistrano部署的工具： / p>

Gemfile

  group：开发吗
宝石'capistrano-rails'
宝石'capistrano-rvm'
宝石'capistrano-passenger'
宝石'capistrano-nvm'，要求：假
 gem' capistrano-yarn'
 end 
  

在deploy.rb中，我为capistrano添加了一些配置nvm和capistrano纱线。

deploy.rb

  set：nvm_type，：user＃或：system取决于您的nvm设置
 set：nvm_node，'v7.10.0'
 set：nvm_map_bins，％w {node npm yarn} 
 
 set：yarn_target_path，-> {release_path.join（'client'）}＃
设置：yarn_flags，'--production --silent --no-progress'＃默认
设置：yarn_roles，：all＃默认
设置：yarn_env_variables，{} 
  

我也已在linked_dirs中添加了node_modules。

deploy.rb

  set：linked_dirs，％w {日志tmp / pids tmp / cache tmp / socket供应商/捆绑包public / system node_modules client / node_modules} 
  

当我在资产：预编译步骤中执行cap部署时，问题就来了。接下来，您将看到错误日志。

解决方案

该错误几乎告诉您什么地方出错了。在服务器上找不到Yarn或Node。您的安装可能不正确。

按照说明在此处安装它们：

https://nodejs.org/en/download/package-manager/ ＃debian-and-ubuntu-based-linux-distributions

在这里：

< a href = https://yarnpkg.com/lang/zh-CN/docs/install/#linux-tab rel = nofollow noreferrer> https://yarnpkg.com/lang/zh-CN/docs/install/#linux -tab

然后请确保您可以致电：

 在服务器上的
节点
  

如果没有，您可能需要将可执行文件的路径添加到PATH变量中

I have an Ubuntu server to deploy my Rails projects. In my Ubuntu server I had RVM.

Now I want to deploy new projects with Rails 5.1 and webpacker. To deploy this projects, I've installed NVM, npm and yarn in my Ubuntu server.

In my Rails 5.1 / Webpacker project I have following gems for capistrano deployment:

Gemfile

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

In deploy.rb I've added some configurations for capistrano nvm and capistrano yarn.

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, {}

Also I've added node_modules in linked_dirs.

deploy.rb

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

The problem comes when I execute cap deploy in assets:precompile step. Next you have the error log.

terminal log

解决方案

The error tells you pretty much what's wrong. Neither Yarn or Node can be found on the server. Your installation might be incorrect.

Follow instructions to install both here:

https://nodejs.org/en/download/package-manager/#debian-and-ubuntu-based-linux-distributions

and here:

https://yarnpkg.com/lang/en/docs/install/#linux-tab

Then make sure you can call:

yarn
node

On the server. If not, you might need to add paths to executables into your PATH variable
