安装 Ruby exiftool-rb

如何解决安装 Ruby exiftool-rb

请帮我为 Bitnami Ruby 安装 exiftool。我做错了什么，但我不知道是什么。

安装过程建议使用 exiftool_vendored https://github.com/exiftool-rb/exiftool_vendored.rb，它按预期显示此示例。

> irb(main):001:0> require 'exiftool_vendored'
=> true
irb(main):002:0> Exiftool.command
=> "/Users/sergey/.rbenv/versions/2.7.2/lib/ruby/gems/2.7.0/gems/exiftool_vendored-12.15.0/bin/exiftool"
irb(main):003:0> Exiftool.exiftool_version
=> "12.15"

我有

knot@Pond:~/rubystack/projects/dupes irb
irb(main):001:0> require 'exiftool_vendored'    => true
irb(main):002:0> Exiftool.command               => "/home/knot/rubystack/ruby/lib/ruby/gems/2.7.0/gems/exiftool_vendored-12.18.0/bin/exiftool"
irb(main):003:0> Exiftool.exiftool_version      => ""

irb(main):004:0> require 'exiftool'             => false
irb(main):005:0> e = Exiftool.new("IMG_20140812_104441.jpg")                                                                                                                    Traceback (most recent call last):
