ruby-on-rails - 生产中 image_optim_pack 丢失二进制文件错误

Question

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

ImageOptim::BinResolver::Error occurred

Answer 1

tl;dr，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"

要获取有关哪个部分发生故障的信息，请运行:

$ bundle exec image_optim --info

我看到这样的东西:

$ bundle exec image_optim --info

它没有说明 worker 失败的原因。但您可以运行工作程序二进制文件来找出答案:

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版本，它只是2.12。如果您能够通过系统的包管理器升级 glibc，请先尝试一下。如果您无法升级 glibc，则只需使用如上所述的旧版本的 gems。
