问题
I'm having a really noob problem with importing files in Ruby. I'm making a Ruby app in Windows XP. All the class files for the app are in "C:/Documents/Prgm/Surveyor_Ruby/lib"
. But when I require
a file in another file, neither ruby nor irb can find the required file.
The current directory's contents:
C:\Documents\Prgm\Surveyor_Ruby\lib>dir
Volume in drive C has no label.
Volume Serial Number is AAAA-BBBB
Directory of C:\Documents\Prgm\Surveyor_Ruby\lib
10/09/2010 06:32 PM <DIR> .
10/09/2010 06:32 PM <DIR> ..
10/08/2010 03:22 PM 5,462 main (commented).rb
10/08/2010 03:41 PM 92 question.rb
10/08/2010 09:06 PM 2,809 survey.rb
10/09/2010 06:25 PM 661 surveyor.rb
10/08/2010 01:39 PM 1,546 test.rb
5 File(s) 10,570 bytes
2 Dir(s) 40,255,045,632 bytes free
Confirmation that irb is in correct directory:
C:\Documents\Prgm\Surveyor_Ruby\lib>irb
irb(main):001:0> Dir.pwd
=> "C:/Documents/Prgm/Surveyor_Ruby/lib"
...yet irb can't load survey.rb:
irb(main):002:0> require 'survey'
LoadError: no such file to load -- survey
from <internal:lib/rubygems/custom_require>:29:in `require'
from <internal:lib/rubygems/custom_require>:29:in `require'
from (irb):2
from C:/Ruby192/bin/irb:12:in `<main>'
回答1:
None of these worked for me, but this did:
irb -I .
>require 'file'
=> true
回答2:
require './hede'
or
require_relative 'hede'
This works for me in both Ruby (1.9.3) and JRuby (1.7.x) on linux. I haven't tested it on windows.
回答3:
Noticed the same behavior but my linux roots had me try:.\file.rb
and it loaded into the irb. Try explicitly declaring the current directory.
回答4:
How about this command? A little cumbersome to write but really clean and it should always work:
➜ $ irb > require "#{Dir.pwd}/file_to_load.rb" => true
回答5:
it's damn dirty, but you can always do at the very first line:
$: << '.'
and off you go with pwd'ed require. It's quite useful for interactive/creative testing with IRB
回答6:
I believe both of the previous posts are correct, just for different uses. In IRB use an absolute path with require
, with a file you can also use require
with an absolute path, or use require_relative
.
回答7:
If you're trying to do this with rvmsudo, I found this worked for me:
rvmsudo irb -I '/Absolute/path/to/your/project'
