红宝石需要问题（与$ LOAD_PATH有关） [英] ruby require problem (something to do with $LOAD_PATH)

问题描述

我尝试使用我刚刚安装的宝石（通过 sudo gem install excelsior ）像这样

需要'rubygems'

需要'excelsior'

...

这在irb中可以正常工作，但是当我将完全相同的代码粘贴到.rb文件并尝试使用ruby运行时， code>< internal：lib / ruby​​gems / custom_require>：29：in require'：no such file to load - excelsior（LoadError）

我认为它与加载路径显然与ruby的irb完全不同（我在Mac上，不记得我是如何安装我使用的ruby版本的）。

那么如何配置ruby使其具有与irb相同的加载路径？

一条额外的信息：一些宝石的工作，但不是全部：S

解决方案

要查看两个可执行文件是否是不同版本的ruby d），请求它做

  puts RUBY_VERSION 
  

I'm trying to use a gem i just installed (via sudo gem install excelsior) like so

require 'rubygems'

require 'excelsior'

...

This works fine in irb, but when I stick exactly the same code into an .rb file and try run it with ruby I get <internal:lib/rubygems/custom_require>:29:in require': no such file to load -- excelsior (LoadError)

I guess it has something to do with the load paths apparently being completely different in irb from ruby (I'm on a mac and don't remember exactly how I installed the version of ruby I'm using).

So how do I configure ruby to have the same loadpath as irb?

One extra piece of info: some gems work, but not all :S

解决方案

To see if the two executables are different versions of ruby (as suspected by some), ask it to do

puts RUBY_VERSION
