我尝试从我的rails 3.2应用程序上传CKEditor中的文件时收到此错误。
我已经使用了capistrano进行部署，现在它仍然坚持这个错误。
它适用于我的本地和UAT环境，但不适用于生产环境。
以前我有访问被拒绝的问题我修复了这个问题，现在我收到了以下错误：
An Errno::EEXIST occurred in pictures#create_pic:

我该如何解决这个问题以及这个错误意味着什么？
答案 0 :(得分：1)
最明显的解决方案是允许webserver按原样生成public/system目录。在deploy.rb删除它：
set :linked_dirs, fetch(:linked_dirs, []).push(
%w|log tmp/pids tmp/cache tmp/sockets vendor/bundle|
)
现在，服务器应该在首次访问时使用适当的权限创建此目录。在您当前的场景中，此目录由部署脚本创建，该脚本运行[我想]不是作为Web服务器用户。
如果此目录不为空且您仍想部署它，只需指示capistrano chown它由网络服务器用户拥有。
作为最后的手段，人们可能会将权利设置为777，但我坚决认为这是解决问题的最糟糕方式。
答案 1 :(得分：0)
我已修复此问题，我注意到其他一些用户对s3fs-passwd文件夹中的/etc文件有权限。通过chown deploy:deploy s3fs-passwd部署用户对该文件的访问权限，/public/system开始在安装时显示正确的文件权限，而不是?? ?????，并且上传工作正常。
答案 2 :(得分：0)
在我的情况下，我有同样的错误，原因是public/system是一个符号链接（我正在迁移）。我可以通过使用 bind mount 而不是符号链接来欺骗rails而不是失败：
mount --bind /orig/public/system /your/public/system
希望它有所帮助。
