我正在尝试使用回形针优化器部署 Rails 应用程序，它给我一个关于缺少二进制文件的错误。我捆绑了 image_optim_pack 来提供二进制文件，但仍然得到这个：

tl；博士，image_optim_pack 中的二进制文件可能是针对比您尝试运行它的系统更新的系统构建的。尝试查找适用于您的系统的最新版本的 image_optim_pack。对我来说，以下版本有效：

gem "image_optim", "~> 0.25"
gem "image_optim_pack", "= 0.2.3"

更多细节

要获取有关失败的部分的信息，请运行：

$ bundle exec image_optim --info

我看到这样的事情：

$ bundle exec image_optim --info

它没有说明工人失败的原因。但是您可以运行工作程序二进制文件来找出：

我认为重要的部分是：

version `GLIBC_2.14' not found

我检查了我系统上安装的 glibc 的版本，它只有 2.12。如果您能够通过系统的包管理器升级 glibc，请先尝试。如果您无法升级 glibc，则只需使用旧版本的 gems，如上所述。

我对image_optim_pack版本0.5.020170815有同样的问题。

升级到最新版本（截至目前为0.5.020170831）为我解决了这个问题。
