来自rubygems的gem安装在gems文件夹中，但是来自github的同一gem安装在bundler / gems中

Question

我有一个小样本的ruby文件和Gemfile，用于诊断使用git作为源时出现的奇怪不一致情况。当我跑步ruby color.rb我收到以下错误。

$ ruby color.rb
Traceback (most recent call last):
        2: from color.rb:1:in `<main>'
        1: from /Users/<user>/.rbenv/versions/2.5.1/lib/ruby/site_ruby/2.5.0/rubygems/core_ext/kernel_require.rb:92:in `require'
/Users/<user>/.rbenv/versions/2.5.1/lib/ruby/site_ruby/2.5.0/rubygems/core_ext/kernel_require.rb:92:in `require': cannot load such file -- colorize (LoadError)

Gemfile

# frozen_string_literal: true

source "https://rubygems.org"

gem 'colorize', :git => 'https://github.com/fazibear/colorize', :ref => '6f1b02342b1c6f45648e5203218c466dc7642125'

Color.rb

require 'colorize'

puts "This is blue".colorize(:blue)

问题

据我所知，我以这种方式在Gemfile中指定的来自github的gems ...

gem 'colorize', :git => 'https://github.com/fazibear/colorize', :ref => '6f1b02342b1c6f45648e5203218c466dc7642125'

...并使用bundle install安装，将安装在此目录中

/Users/<user>/.rbenv/versions/2.5.1/lib/ruby/gems/2.5.0/bundler/gems

但是，我以这种方式在我的Gemfile中指定的来自rubygems的宝石...

source "https://rubygems.org"
gem 'colorize', '0.7.3' 

...并且也使用bundle install安装，将安装在此目录中

/Users/<user>/.rbenv/versions/2.5.1/lib/ruby/gems/2.5.0/gems

我只是以colorize为例，但这与其他任何宝石都一样。

[我想知道如何直接从github获取我所有的宝石，无论是通过分支还是通过引用将其安装在2.5.0/gems文件夹而不是2.5.0/bundler/gems目录中。

这样做的原因是，每当我运行我的代码时，它都会never使用2.5.0/bundler/gems目录中的gems，并且仅从2.5.0/gems目录中运行。我想另一种有效的解决方案也可以解释如何让我的项目使用2.5.0/bundler/gems目录中的gems，但是主要问题是，当使用github作为源代码时，它将gems与我的项目安装在另一个目录中从那里得到宝石。

环境信息

$ rbenv version

$ ruby -v

注意：目前，我的Gemfile中已安装gem 'colorize', '0.7.3'的gem

您在应用程序中使用捆绑程序和Gemfile，但未通过捆绑程序调用您的应用程序，因此，当您调用require 'colorize'时，它不起作用，因为只有捆绑程序才能告诉应用程序在哪里找到宝石。

您最简单的解决方案是使用捆绑程序调用您的应用程序：

bundle exec ruby color.rb
