无法在生产中上传回形针图像（AWS）

Question

我的回形针上传产品似乎有问题。 我已经与Capistrano一起部署到AWS。 以下是我尝试为用户上传图片时收到的错误。

Completed 500 Internal Server Error in 3695ms

Errno::EEXIST (File exists - /home/app/xxx.com/current/public/system):
  app/controllers/users_controller.rb:94:in `update'

这是视图生成的图像链接：

<img alt="10-m" src="/system/styles/dimages/000/000/519/original/10-m.jpg?1379454321">

但是，当我尝试在我的应用程序中浏览到此目录时，我不能。 也许这是一个权限问题？ 系统的文件夹名称显示为红色

app@mothership:~/xxx.com/current/public$ ls
403.html  404.html  422.html  500.html  assets  favicon.ico  robots.txt  system
app@mothership:~/xxx.com/current/public$ cd system
-bash: cd: system: No such file or directory

Answer 1

Paperclip正在尝试创建/home/app/xxx.com/current/public/system目录，但它已经存在了。 这可能是由于Capistrano部署中的符号链接无效。

检查文件并使用ls -l查看它是否是指向正确位置的符号链接。 如果没有，请通过创建目标或更改位置来更新符号链接。
