Ruby on rails 3 使用capistrano部署错误失败："；sh-c'；cat/home…….当前/修订版

capistrano将应用程序部署到VPS时出错。 cap deploy:setup和cap deploy:check执行时没有错误

当我尝试cap-deploy:cold或干脆cap-deploy时，我得到了以下结果

[deploy:update_code] rolling back

我自己找到了答案

首先从deploy.rb中删除此代码段

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

然后从capfile中删除load“deploy/assets”，并运行

cap deploy:cold

这将不会出错，但仅在初始部署时有效。然后像往常一样在服务器上“sudo service nginx restart”，并添加回所有deleter之前的代码段

最后，您可能会有一个错误：

ActionView::Template::Error (File to import not found or unreadable: bootstrap.
Load path: /home/yasinishyn/apps/mkv/releases/20130506160725
(in /home/yasinishyn/apps/mkv/releases/20130506160725/app/assets/stylesheets/bootstrap_and_overrides.css.scss)):

如果没有，请更改资产中的某些内容，例如在application.css顶部添加空间。然后git add.，git commit，git推送，然后重新运行

cap deploy

砰！！有效：）

cap deploy
