Question

我有一个脚本需要从项目Gemfile中定义的宝石中获取特定文件。

AtomicInteger value = new AtomicInteger(0);
Integer anotherCalculatedValue = ...;
value.getAndAccumulate(anotherCalculatedValue, Math::max);

当我运行脚本时，出现无法加载#!/usr/bin/env ruby require 'some_gem/helpers/some_helper' ... rest of script的错误。如果我与some_helper.rb一起运行，那么一切正常我知道bundle exec将Gems暴露给$ LOAD_PATH，让bundle exec command...工作。有没有办法将该功能移到脚本中，这样用户就不必键入require？

在我需要gem文件之前，我是否只需要在脚本中添加bundle exec？

：）

#!/usr/bin/env ruby
require 'rubygems' # because reasons.. most probably it is not needed unless you are using really old ruby where it is not loaded by default
                   # also at the moment rubygems and bundler are being merged :) 
require 'bundler/setup' # for things installed with bundler
require 'some_gem/helpers/some_helper'

需要来自Ruby脚本中的gem文件，而不需要bundle exec
