这是运行任务 Cap deploy:setup 以使用 Capistrano 和 Unicorn 部署 ubuntu 服务器后发生的错误。如果您知道答案，请在这里帮助我？这是反映在终端上的错误-

[100.116.4.74] sh -c 'cp -RPp /home/deployer/apps/mcash/shared/cached-copy /home/deployer/apps/mcash/releases/20120417074244 && (echo 8f69f0a524dcecef478bad74df4a983d3cdad480 > /home/deployer/ mcash/releases/20120417074244/REVISION)' ** [out :: 100.116.4.75] cp：无法创建目录 `/home/deployer/apps/mcash/releases/20120417074244' ** [out :: 100.116.4.75]：否这样的文件或目录

失败：“sh -c 'cp -RPp /home/deployer/apps/mcash/shared/cached-copy /home/deployer/apps/mcash/releases/20120417074244 && (echo 8f69f0a524dcecef478bad74df4a983d3cdad480 > /home/deployer/apps/mcash/发布/20120417074244/REVISION)'" 在 100.116.4.74

这是整个 deploy.rb 文件-

需要“捆绑器/capistrano”
