回形针错误:NotIdentifiedByImageMagickError [英] Paperclip Error: NotIdentifiedByImageMagickError

问题描述

我已经安装了一个带有 Paperclip 的 Rails，现在可以正常工作一段时间了，但在最近的部署中它坏了.我相信它与 gemfile 更新同时发生，因为机器上的其他任何东西都没有改变.错误是:

I've had a rails install with Paperclip working just fine for a while now and in a recent deploy it has broken. I believe it coincided with a gemfile update, because nothing else on the machine has changed. The error is:

Command :: file -b --mime :file
[paperclip] Error while determining content type: Command 'file -b --mime :file' returned 1. Expected 0

这是一个我已经验证有效的 png 文件.当我在图像上运行 'file -b --mime' 时:

This is on a png file that I've verified to be valid. When I run 'file -b --mime' on the image I get:

image/png; charset=binary

我后来也得到了这个:

Command :: identify -format %wx%h :file
[paperclip] An error was received while processing: #<Paperclip::Errors::NotIdentifiedByImageMagickError: /tmp/song_waveform_3010520121008-23335-165xag4.png20121008-23335-j8e18p is not recognized by the 'identify' command.>

我做了一个 which 文件，它给了我/usr/bin 所以我尝试在 production.rb 中设置 Paperclip.options[:command_path] = "/usr/bin/" 没有任何变化.

I did a which file and it gave me /usr/bin so I tried setting the Paperclip.options[:command_path] = "/usr/bin/" in production.rb with no change.

我想不出为什么会发生这种情况.也许它没有指向正确的目录?我有点迷失在这里.

I can't think of why this could be happening. Perhaps it's not pointing to the right directory? I'm a bit lost here.

推荐答案

这很可能是由可卡因 4 中的 API 更改引起的，而 Paperclip 尚未赶上.通过将此行插入您的 Gemfile 来尝试使用早期版本的可卡因:

Most likely this is caused by the API change in Cocaine 4 which Paperclip has not caught up to yet. Try using the earlier version of Cocaine by inserting this line into your Gemfile:

gem "cocaine", "= 0.3.2"
