macOS中的gem位置，帶有chruby和TextMate首選項

Question

我無法讓Ruby寶石在TextMate（TM）上運行並在macOS上使用chruby。

大約六個月前在2017年iMac上清潔安裝Mojave（現為v10.14.4）。

嘗試使用Ruby-2.6.2，雖然已經安裝了早期版本。 System Ruby是v2.3.7

我至少在三個地方找到了寶石：

~/.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依賴於gem和Ruby位置的首選項。 首先，我有以下幾點： GEM_HOME沒有設置，因為我不明白為什么需要它，雖然我經常閱讀如圖所示設置或類似。 GEM_HOME和GEM_PATH定義為

GEM_PATH提供可以找到寶石的位置（可能有幾個）。

GEM_HOME是安裝寶石的地方（默認情況下）。

問題是當我在TM中運行此腳本（在未包含錯誤之后）

#!/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'

結果是：

TextMate將它放在輸出的右上角

第19行require 'mini_exiftool'

mini_exiftool是在gem列表中，但為什么會出錯呢？

如果我使用系統Ruby運行腳本（采用默認值，TM中沒有設置）

該腳本使用以下輸出運行：

這個特殊的腳本在2.3.7中是可以的，但是其他的可能不是。

謝謝你的幫助。

這篇文章簡化了我之前的帖子 。 我想我已經把問題解決了。

將GEM_HOME和GEM_PATH更改為$HOME/.gem/ruby/2.6.2:$HOME/.rubies/ruby-2.6.2/lib/ruby/gems/2.6.0基於從運行時顯示的內容復制這些變量從終端。 盧的評論使我對報道的內容看起來有點困難。 基本上我在第二條路徑（冒號后）缺少$HOME/ 。 幾個月來我一直在擺弄這個
