Ruby on rails Capistrano正在尝试创建/public目录

我目前正在尝试使用Capistrano进行我的第一次Rails部署，我遇到了一个无法克服的障碍。在

cap部署期间

我收到一个错误“

mkdir:cannotcreatedirectory

/public'`”

有关详情：

• Rails版本：3.2.6
• Capistrano版本：2.13.5
• 在Dreamhost上运行
• 我正在预编译我的资产（我怀疑这是问题的一部分），所以我的Capfile中有

  load'deploy/assets'

我遵循了这里的指导：在大部分情况下，我也会在网上搜索一些关于Capistrano的其他文章

deploy.rb

需要“bundler/capistrano”
ssh_选项[：转发_代理]=真
ssh_选项[File.join（ENV[“HOME”]、“.ssh”、“id_rsa-dreamhost”）]
设置：应用程序“”
集合：存储库，“git@bitbucket.org：/#{application}.git“
设置：服务器名称“”
set:scm，：git#您可以显式设置：scm，否则Capistrano将根据已知的版本控制目录名进行智能猜测
#或者：`accurev`、`bzr`、`cvs`、`darcs`、`git`、`mercurial`、`perforce`、`subversion`或`none``
设置：签出，“导出”
set:deploy\u via，：remote\u缓存
集合：分支，“主”
设置：基本路径“/home/”
设置：将部署到“#{base_path}/#{application}”
设置：保持释放，3
设置：用户“'
场景：跑步者
设置：使用_sudo，false
默认运行选项[：pty]=真
设置：共享路径“/home/”
set:release_path，“#{base_path}/#{application}”
角色：web“#您的HTTP服务器、Apache/等
角色：应用程序“”。#这可能与您的“Web”服务器相同
角色：db，“，：primary=>true#Rails迁移将在这里运行
#如果要清理每个部署上的旧版本，请取消注释：
#在“部署：重新启动”、“部署：清理”之后
#如果您仍在使用脚本/收割者助手，则需要
#这些http://github.com/rails/irs_process_scripts
#如果您使用的是乘客mod_rails，请取消注释：
名称空间：deploydo
任务：开始做；结束
任务：停止做；结束
desc“通过触摸Restart.txt文件重新启动应用程序。”
任务：重新启动，：角色=>:app，：except=>{:no\u release=>true}do
运行“touch{File.join（当前路径，'tmp'，'restart.txt'）”
结束
desc“从共享文件夹更新特定于环境的文件。”
任务：symlink_shared，：roles=>[：app]do
运行“ln-s{shared_path}/app_config.yml{release_path}/config/”
运行“rm#{release_path}/config/database.yml”
运行“ln-s{shared_path}/database.yml{release_path}/config/”
运行“rm{release\u path}/public/.htaccess”
运行“ln-s{shared_path}/.htaccess{release_path}/public/”
结束
结束
在“部署：重新启动”之前，“部署：符号链接\u共享”
在“部署：更新代码”之后，“部署：迁移”
