Question

我最近在Heroku的Rails 4应用程序中安装了paperclip-optimizer gem。每当我尝试保存上传的图像附件时，我都会收到以下错误：来自Heroku的日志中的jpegrecompress worker: 'jpeg-recompress' not found;，但不会出现在localhost上。

我不确定我错过了什么。我似乎无法找到关于此问题的单个StackOverflow帖子，博客文章或其他资源。

这是我的config/initializers/paperclip_optimizer.rb：

Paperclip::PaperclipOptimizer.default_options = {
    skip_missing_workers: true,
    advpng: false,
    gifsicle: false,
    jhead: false,
    jpegoptim: false,
    jpegrecompress: true,
    jpegtran: false,
    optipng: false,
    pngcrush: false,
    pngout: false,
    pngquant: true,
    svgo: false,
    nice: 10,             # Nice level (defaults to 10)
    threads: 1,           # Number of threads or disable (defaults to number of processors)
    verbose: false,       # Verbose output (defaults to false)
    pack: nil,            # Require image_optim_pack or disable it, by default image_optim_pack will be used if available,
    allow_lossy: true,   # Allow lossy workers and optimizations (defaults to false)
    jpegrecompress: {
        quality: 2          # JPEG quality preset: 0 - low, 1 - medium, 2 - high, 3 - veryhigh (defaults to 3)
    },
    pngquant: {
        quality: 100..100,  # min..max - don't save below min, use less colors below max (both in range 0..100; in yaml - !ruby/range 0..100) (defaults to 100..100)
        speed: 3            # speed/quality trade-off: 1 - slow, 3 - default, 11 - fast & rough (defaults to 3)
    }
}

在photo.rb模型中，我有：

has_attached_file :image, styles: { large: "600x600>", medium: "300x300>", thumb: "100x100>" }, default_url: "", processors: [:thumbnail, :paperclip_optimizer]

在Heroku的.buildpacks文件中，我有：

https://github.com/ddollar/heroku-buildpack-multi.git
https://github.com/heroku/heroku-buildpack-ruby.git
https://github.com/bobbus/image-optim-buildpack.git

我添加了Ruby buildpack来解决this problem我之前遇到的问题，但现在似乎没有加载multi和image-optim构建包。

谢谢！
