Ruby:如何“要求"当前工作目录中的文件? [英] Ruby: how to "require" a file from the current working dir?
问题描述
如何从当前文件夹中获取文件?
How do I require a file from the current folder?
我有一个名为sql_parser.rb
的文件,其中包含一个类.我想将此文件也包含在同一文件夹的另一个文件中,所以我使用了:
I have a file called sql_parser.rb
that contains a class. I want to include this in another file also in the same folder, so I used:
require 'sql_parser'
从该文件夹运行时失败:
That fails when I run from that folder:
LoadError: no such file to load -- sql_parser
我尝试在该文件所在的文件夹中使用IRB,并从那里要求它,但是存在相同的问题.
I tried using IRB in the folder where this file exists and requiring it from there, but had the same issue.
