gem macOS 中具有 chruby 和 TextMate 首选项的位置

Question

我无法让 Ruby gems 在 macOS 上正确使用 TextMate (TM) 和 chruby。

大约六个月前，在 2017 iMac 上全新安装了 Mojave（现在是 v10.14.4）。

尝试使用Ruby-2.6.2，虽然已经安装了更早的版本。系统 Ruby 是 v2.3.7

我至少在三个位置得到了 gem：

~/.rubies/ruby-2.6.2/lib/ruby/gems/2.6.0/gems/
~/.gem/ruby/2.6.2/gems/
/Library/Ruby/Gems/2.3.0/gems/

TextMate 依赖其 gem 和 Ruby 位置的首选项。作为开始，我有以下内容： GEM_HOME 未设置，因为我不明白为什么需要它，尽管我经常阅读以如图所示或类似方式设置它。 GEM_HOME and GEM_PATH 定义为

GEM_PATH 提供可以找到 gem 的位置（可能有几个）。

GEM_HOME 是安装 gems 的地方（默认）。

问题是我在TM运行这个脚本时（报错后不包含）

#!/usr/bin/env ruby
system ('gem env') # for debugging
puts "\nGem.path: #{Gem.path}"
puts "\ngem list:"
system ('gem list') # for debugging 
require 'fileutils'
include FileUtils
require 'find'
require 'yaml'
require "time"
require 'irb'
require 'mini_exiftool'

结果是：

TextMate 将其放在输出的右上角

第 19 行是 require 'mini_exiftool'

mini_exiftool在gem列表中，但为什么会报错？

如果我运行使用系统Ruby的脚本（采用默认值，TM 中没有任何设置）

脚本运行s 具有以下输出：

gem list:

此特定脚本适用于 2.3.7，但其他脚本可能不适用。

感谢您的帮助。

此贴是 earlier posting from me 的简化版。我想我已经把问题归结了。

Answer 1

将 GEM_HOME 和 GEM_PATH 更改为 $HOME/.gem/ruby/2.6.2:$HOME/.rubies/ruby-2.6.2/lib/ruby/gems/2.6.0 基于从终端运行时显示的变量中复制这些变量。卢的评论让我更加认真地审视了所报道的内容。基本上我在第二条路径（冒号之后）中缺少 $HOME/ 。我已经摆弄了几个月
