Capistrano部署 – 资产预编译错误
我正在与Capistrano一起部署到我的新VPS。 在第一次部署（上限部署）之后，一切正常（站点正在运行），但第二次部署在资产上失败：预编译错误。
我正在运行rails 3.2.13，ruby 2.0.0，rvm。
错误：

我对Capistrano很新，所以请尝试清楚地解释解决方案。 感谢您的支持！
您的vpn服务器上的操作内存大小似乎很小。 （ Vpn不提供内存交换）因此操作系统会终止您的部署过程。
解决方案是在本地编译资产（在开发机器上）
将deploy:assets:precompile任务添加到deploy.rb文件中（这是Capistrano 2）
namespace :deploy do . . . 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 end end
然后只需重新部署app $ bundle exec cap deploy希望它有所帮助
