Capistrano没有创建符号链接

Question

我已经创建了一个用于部署网站的上限文件，除了没有创建符号链接外，它都可以工作，我最近格式化了我的计算机，所以可能语法已经改变，我不确定。

namespace :myproject do
    task :symlink, :roles => :app do
       run "ln -nfs #{shared_path}/site_files/apache_password/.htaccess #{release_path}/src/public"
       run "ln -nfs #{shared_path}/site_files/tmp #{release_path}/src/private/app/tmp"
       run "ln -nfs #{shared_path}/site_files/media #{release_path}/src/public/media"
       run "ln -nfs #{shared_path}/site_files/Config/database.php #{release_path}/src/private/app/Config/database.php"
       run "ln -nfs #{shared_path}/site_files/Config/core.php #{release_path}/src/private/app/Config/core.php"
    end
end

after "deploy:symlink", "myproject:symlink"

终端响应：
