Capistrano 3在资产上失败：预编译

我无法在资产上部署我的Rails 4应用程序：奇怪的错误：预编译。似乎任务无法使用已安装的宝石。 在本地机器的开发和生产环境中，所有工作都很完美。部署日志的一部分：

我认为问题在于放置宝石。第一行日志告诉我/ var / www / app / shared / bundle中的所有宝石以及它的真相 - 它们确实在那里。但是，如果我以部署用户身份运行rvm 2.2.0@gemset do gem list，我在列表中看不到已安装的宝石：

deployer@server:/var/www/app/current$ rvm 2.2.0@gemset do gem list

*** LOCAL GEMS ***

bigdecimal (1.2.6)

当我从app的文件夹中运行bundle时，我可以看到已安装宝石的完整列表：

我在单用户模式下使用rvm进行开发和生产，在这里使用一些我的文件：

# deploy.rb
lock '3.2.1'

set :application, 'App'
set :repo_url, 'git@bitbucket.org:app/app.com.git'
set :deploy_to, '/var/www/app'

set :rvm_ruby_version, '2.2.0@gemset'
set :unicorn_env, 'production'
set :rails_env, :production
set :linked_files, %w{config/database.yml config/secrets.yml config/scp.yml}

set :linked_dirs, %w{bin log tmp/pids tmp/cache tmp/sockets vendor/bundle public/system}
namespace :deploy do

    desc 'Restart application'
    task :restart do
        invoke 'unicorn:restart'
    end

    after :restart, :clear_cache do
        on roles(:web), in: :groups, limit: 3, wait: 10 do
        end
    end

after :publishing, :restart
end

Capfile 

# Capfile
require 'capistrano/setup'
require 'capistrano/deploy'
require 'capistrano3/unicorn'
require 'whenever/capistrano'
require 'capistrano/rvm'
require 'capistrano/bundler'
require 'capistrano/rails'

Dir.glob('lib/capistrano/tasks/*.rake').each { |r| import r }

Front.css.scss在application.rb

中设置为预编译 
# front.css.scss
@import "compass";
@import "compass/utilities/sprites";
@import "sprites/*.png";
@include all-sprites-sprites;
@import "breakpoint";
$breakpoint-tiny : 0 660px;

@import "static";

例如static.css.scss：

/* static.css.scss */
.blog {
    @include sprites-sprite(blog-gray);
    &:hover {
        @include sprites-sprite(blog-color);
    }
}

如果我从static.css.scss中删除所有mixins，则部署将成功完成。

1 个答案:

答案 0 :(得分：2)

我解决了自己的问题，它与capistrano甚至rvm无关。 我为我的应用程序使用了两种布局：front.html.slim和admin.html.slim。他们每个人都有自己的css列表，front.css和admin.css。

在front.css.scss中我有这样的事情：

@import "compass";
@import "compass/utilities/sprites";

在admin.css.scss中我得到了：

/*
 *= require base
 *= require posts
 *= require projects

当我将admin.css.scss样式更改为@import assets:precompile成功完成后。 Thanx @RAJ的建议。
