macOS中带有chruby和TextMate首选项的gem位置

Question

我很难让Ruby与TextMate (TM)和chruby在macOS上正常工作。

大约六个月前，在2017年的iMac上安装了Mojave (现在的10.14.4版)。

尝试使用Ruby-2.6.2，尽管已经安装了早期版本。System是v2.3.7

我在至少三个地点得到了宝石：

~/.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依赖于它对gem和Ruby的偏好。首先，我有以下几点：

GEM_HOME是未设置的，因为我不明白为什么需要它，尽管我经常阅读来设置它，如图所示或类似的。PATH被定义为

GEM_PATH提供了可以找到宝石的位置(可能有几个)。

GEM_HOME是安装gems的地方(默认情况下)。

问题是，当我在TM中运行这个脚本(在错误不包括之后)

#!/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，但是为什么会出错呢？

如果我使用system运行脚本(默认情况下，在TM中没有设置)

脚本运行时具有以下输出：

gem list:

这个特定的脚本可以用于2.3.7，但其他脚本可能不行。

谢谢你的帮助。

此公告是对earlier posting from me的简化。我想我已经把这个问题理清了。

根据从终端运行时显示的变量复制这些变量，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。陆先生的评论让我更难了解报道的内容。基本上，我在第二个路径(在冒号之后)缺少了$HOME/。我已经摆弄了好几个月了
