“要求”的问题在于，关键字未找到要加载的文件 [英] A problem with the "require" keyword not finding the file to load

本文介绍了“要求”的问题在于，关键字未找到要加载的文件的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我在ruby中的require关键字有问题，我只是使用下载一个gem： 

  gem install thegem

当我尝试运行一个示例时，收到以下错误消息：

 < internal：lib / ruby​​gems / custom_require>：29：在'require'中：不需要加载这样的文件 -  
 ./thegem/some / path（LoadError）

在问题代码中：

  needs_to_load = a_class 
需要gem / some / path /＃{needs_to_load}

我是一个Ruby noob，学习了我的方式，但我不确定这是什么，谷歌搜索没有帮助，但透露它可能是由于需要一个相对路径，但将第二行更改为下列内容并没有帮助：

  require./gem/some/path/# {needs_to_load}

我将RVM与以下ruby版本配合使用： ruby-1.9.2-head 。



（p。抱歉，如果在相关问题字段中我没有看到任何内容，请提问）

$ b $如果你使用正常的 gem install somegem ，那么你应该能够 require'somegem'，没有任何路径添加到gem的名称。 require_relative 对于安装在普通Ruby搜索路径之外的宝石和模块非常有用，例如您已经编写并嵌入到 lib $ b $>使用 gem env 并追加其输出通过编辑来回答原来的问题，这将帮助我们确定这是否是一个路径问题。因为您使用的是RVM，所以您的宝石路径应该指向您的〜/ .rvm 文件夹。如果你做了 rvm info 它也会给你路径信息，所以比较这两个命令的输出来看它们是否一致。


I have a problem with the "require" keyword in ruby, I just downloaded a gem using:

gem install thegem

And when I tried running an example I received the following error:

<internal:lib/rubygems/custom_require>:29:in `require': no such file to load -- 
    ./thegem/some/path (LoadError)

In the code where the problem is:

needs_to_load = a_class
require "gem/some/path/#{needs_to_load}"

I'm a Ruby noob learning my way around and am not sure what this is, a google search didn't help but revealed that it may be due to needing a relative path, however changing the 2nd line to the following did not help:

require "./gem/some/path/#{needs_to_load}"

I'm using RVM with the following ruby version: ruby-1.9.2-head.

(p.s. sorry if this has been asked before I didn't see anything for it in the related questions field)

解决方案

If you use a normal gem install somegem, then you should be able to require 'somegem', without any path added to the name of the gem. require_relative is useful for gems and modules that are installed somewhere out of the normal Ruby search paths, such as ones you've written and embedded in a lib directory immediately below the calling script's directory.

Use gem env and append its output to your original question by editing it, which will help us determine if it's a pathing issue. Because you are using RVM, your gem path should be pointing into your ~/.rvm folder. If you do rvm info it will also give you path info, so compare the output of those two commands to see if they are consistent.
