ruby-on-rails-3.1 - 为什么我从 Paperclip 收到 "Too many open files - convert"错误？

Question

我正在尝试为回形针运行 clean rake 任务，因为我刚刚完成将所有以前的 png 图像转换为 jpg 并且我不断收到

rake aborted!
Too many open files - convert

我确定我有超过 10,000 张图片，有 6 种不同的风格，关于如何解决这个问题有什么想法吗？

"That means you aren't closing the file after assigning to Paperclip. You have to close the file after >assign it to the attachment, as Paperclip clones your file as a Tempfile right after the assignment. >We've done that to prevent undesired behavior (say, trying to rewind the file after you assign it to >Paperclip.)"

file = File.open("foo.jpg")
@user.attachment = file
file.close # totally safe!
