Question

我正在尝试解决我最近遇到的问题，从带有cap: production deploy:migrations的github生产分支部署到我的服务器。

我看到一个可能的解决方案是关注此页面：http://www.kudelabs.com/2012/03/28/rails-3-2-cap-deploy-with-assets

但是我在rake assets:precompile部分遇到错误，在本地运行它。终端建议我这样做 bundle exec rake assets:precompile，我做了，但我得到了以下内容：

root@ubuntu:~/myapp# bundle exec rake assets:precompile

谁能告诉我问题可能在哪里？

如果这是初始部署，请尝试删除

load 'deploy/assets'

然后尝试

cap deploy:setup
cap deploy:cold

在这种情况下，你的应用程序将被部署，但没有任何资产:) 然后你需要添加这个：

#to the top of your deploy.rb namespace :deploy block
namespace :assets do
    task :precompile, :roles => :web do
     from = source.next_revision(current_revision)
     if capture("cd #{latest_release} && #{source.local.log(from)} vendor/assets/ lib/assets/ app/assets/ | wc -l").to_i > 0
                    run_locally("rake assets:clean && rake assets:precompile")
                    run_locally "cd public && tar -jcf assets.tar.bz2 assets"
                    top.upload "public/assets.tar.bz2", "#{shared_path}", :via => :scp
                    run "cd #{shared_path} && tar -jxf assets.tar.bz2 && rm assets.tar.bz2"
                    run_locally "rm public/assets.tar.bz2"
                    run_locally("rake assets:clean")
                else
                    logger.info "Skipping asset precompilation because there were no asset changes"
                end
            end

            task :symlink, roles: :web do
                run ("rm -rf #{latest_release}/public/assets &&
                    mkdir -p #{latest_release}/public &&
                    mkdir -p #{shared_path}/assets &&
                    ln -s #{shared_path}/assets #{latest_release}/public/assets")
            end
        end

然后重新检查你的produ.rb中是否有这个

config.serve_static_assets = false

# Compress JavaScripts and CSS
config.assets.compress = true

# Don't fallback to assets pipeline if a precompiled asset is missed
config.assets.compile = false

# Generate digests for assets URLs
config.assets.digest = true

完成所有这些工作后，更改资产中的某些内容，例如在application.css中添加新行，这将告诉“task：precompile”真正预先命令并上传新资产，因为添加了新资产..
