ruby - 安装 gem 时无法将 "\x89"从 ASCII-8BIT 转换为 UTF-8 xxx

Question

我目前正在编写一个 gem，由于某些原因需要包含 WordPress 的完整副本(不完全确定这是否相关)。现在，问题；运行 gem 构建正常，但 gem install 给出此错误消息似乎是针对每个二进制文件(.gif、.png 等)，并且在出现一些错误后，进程停止。

unable to convert "\x89" from ASCII-8BIT to UTF-8 xxx/xxx.xx

某些消息的“x89”标识符不同。

这是一个例子

unable to convert "\xF2" from ASCII-8BIT to UTF-8 for lib/templates/wordpress/wp-admin/images/spinner.gif, skipping
unable to convert "\x89" from ASCII-8BIT to UTF-8 for lib/templates/wordpress/wp-admin/images/stars-2x.png, skipping

unable to convert "\x89" from ASCII-8BIT to UTF-8 for lib/templates/wordpress/wp-content/themes/twentyfifteen/screenshot.png, skipping
unable to convert "\x80" from ASCII-8BIT to UTF-8 for lib/templates/wordpress/wp-content/themes/twentyfourteen/genericons/Genericons-Regular.otf, skipping

我在进程停止前得到的最后一行是

unable to convert "\x89" from ASCII-8BIT to UTF-8 for lib/templates/wordpress/wp-includes/js/mediaelement/bigplay.png, skipping

我在其他地方看到过类似的问题，但在尝试安装时它们都是针对特定 gem 的。我想问的是如何修复我的 gem 以便不产生此错误？

这是我的 gem 规范

require File.expand_path(File.dirname(__FILE__)) + '/lib/gemname.rb'

Gem::Specification.new do |s|
  s.name        = 'gemname'
  s.version     = Gemname::VERSION
  s.executables << 'gemname'
  s.licenses    = ['LICENSE']
  s.summary     = "Short description"
  s.description = "Long description"
  s.authors     = ["Sigurd Berg Svela"]
  s.email       = 'sigurdbergsvela@gmail.com'
  s.files       = `git ls-files -- lib/*`.split("\n")
  s.homepage    = 'https://github.com/sigurdsvela/gemname'
  s.required_ruby_version = '>= 2.0.0'

  gemRootDir = File.dirname(File.expand_path(__FILE__))

  # get an array of submodule dirs by executing 'pwd' inside each submodule
  `git submodule --quiet foreach pwd`.split("\n").each do |submodule_path|

    # for each submodule, change working directory to that submodule
    Dir.chdir(submodule_path) do

      # issue git ls-files in submodule's directory
      submodule_files = `git ls-files`.split("\n")

      # prepend the submodule path to create absolute file paths
      submodule_files_fullpaths = submodule_files.map do |filename|
        "#{submodule_path}/#{filename}"
      end

      # remove leading path parts to get paths relative to the gem's root dir
      # (this assumes, that the gemspec resides in the gem's root dir)
      submodule_files_paths = submodule_files_fullpaths.map do |filename|
        filename.gsub "#{gemRootDir}/", ""
      end

      # add relative paths to gem.files
      s.files += submodule_files_paths
    end

  end

  # Hardcode include gitignores submodule
  Dir.chdir(Boot.dir + "/templates/gitignores") do
    submodule_path = Boot.dir + "/templates/gitignores"

    # issue git ls-files in submodule's directory
    submodule_files = `git ls-files`.split("\n")

    # prepend the submodule path to create absolute file paths
    submodule_files_fullpaths = submodule_files.map do |filename|
      "#{submodule_path}/#{filename}"
    end

    # remove leading path parts to get paths relative to the gem's root dir
    # (this assumes, that the gemspec resides in the gem's root dir)
    submodule_files_paths = submodule_files_fullpaths.map do |filename|
      filename.gsub "#{gemRootDir}/", ""
    end

    # add relative paths to gem.files
    s.files += submodule_files_paths
  end

end

这似乎是 gem 安装程序的错误。但是“gem install germane --no-document”是一个临时解决方案。
