# Ruby 1.4.6 - trouble with require path **URL:** \ **Category:** ruby-talk\ **Created:** [5 November 2004 01:53 UTC](https://rubytalk.org/t/ruby-1-4-6-trouble-with-require-path/14616 "2004-11-05T01:53:43Z")\ **Posts on this page:** 12\ **Page:** 1

I inherited a project that uses Ruby 1.4.6 on a RedHat Linux 6.1J. I copied it onto my RedHat Linux 6.1J machine, but there is a problem when I try to build it; the ruby scripts are unable to find required files (located in the same directory as the scripts) when the script is executed from a different directory. I upgraded to Ruby 1.6.7, which fixed that problem, but the scripts are not quite compatible with the updated Ruby, so I had to revert to the version that was originally used. As an example, lets say I have two ruby scripts in a directory:      /scripts/script1.rb:           #!/usr/bin/ruby           require "script2"            /scripts/script2.rb:           print "Testing...\n"            Command Prompt:      [testing]# cd /scripts      [scripts]# script1.rb      Testing...      [scripts]# cd /testing      [testing]# script1.rb      script1.rb:2:in `require': No such file to load -- script2 (LoadError) With Ruby 1.6.7, it works fine. With Ruby 1.4.6, it can find script1.rb, but not script2.rb. There must be a way to correct this, as the project apparently worked for the original developers. I'm using the same OS, and I added the same ruby options and script directory to my path as specified in their readme (well almost, they said put it in .cshrc, but I had to put it in .tcshrc for it to work):      setenv RUBYOPT '-Ke -rkconv'      set path = ( $path /scripts) I also tried the following:      setenv RUBYOPT '-Ke -rkconv -S'      setenv LOAD\_PATH /scripts      setenv RUBYLIB /scripts So what am I missing here? Does anyone know how I can get this to work correctly WITHOUT ALTERING THE SCRIPTS (because there are hundreds of scripts)? ---

Well, "setenv RUBYLIB /scripts" was the right solution. I don't quite understand what was going on; RUBYLIB was set (as verified by typing "setenv"), but Ruby couldn't find the scripts until I restarted the computer. Then it seemed to work fine. But now I'm having another weird problem where accessing the PATH environment variable is causing Ruby not find scripts. For example:      /scripts/script1.rb:           #!/usr/bin/ruby           print `script3.rb`      /scripts/script2.rb:           #!/usr/bin/ruby           ENV["PATH"].split(/:/).each { |i|                #do nothing           }           print `script3.rb`      /scripts/script3.rb:           #!/usr/bin/ruby           print "Testing...\n"      Command Prompt:           [scripts]# cd /testing           [testing]# script1.rb           Testing....           [testing]# script2.rb           /testing/script2:4: command not found: script3 Any access to ENV["PATH"] seems to cause the problem, for example: print ENV["PATH"] tmp = ENV["PATH"] ENV["PATH"].chomp! Any ideas on this one? ---

Looking at the code for ENV., I don't see anything that would cause this, unless there's some bug in your libc with getenv. Perhaps you should try a bash-like shell instead of a csh-like shell? Oh, try this: puts ENV["PATH"] puts `env | grep path` See if your PATH is really destroyed. > **···** > > Ken Innes (primehalo@hotmail.com) wrote: > > > Well, "setenv RUBYLIB /scripts" was the right solution.

My default shell is bash, but I change to csh to run their scripts (as that's what it said to do in their readme file). Still, I have tried it in both shells with the same results. Anyway, I tried your suggestion, and here's what happens: Try 1:      /scripts/script2.rb:           #!/usr/bin/ruby           puts ENV["PATH"]           puts `env | grep path`      Command Line:           [testing]% script2.rb           /bin:/usr           sh: env: command not found           [testing]% Didn't work because I referenced ENV["PATH"] so it couldn't find "env". Try 2:      /scripts/script2.rb:           #!/usr/bin/ruby           puts ENV["PATH"]           puts `/usr/bin/env | grep path`      Command Line:           [testing]% script2.rb           /bin:/usr                      [testing]% Probably put a blank line because of a difference in case. Try 3:      /scripts/script2.rb:           #!/usr/bin/ruby           puts ENV["PATH"]           puts `/usr/bin/env | grep PATH`      Command Line:           [testing]% script2.rb           /bin:/usr           PATH=/bin:/usr           [testing]% The PATH environment variable still seems to be in tact, but Ruby still can't find any files that are in PATH directories after ENV["PATH"] is accessed. > **···** > > > Ken Innes (primehalo@hotmail.com) wrote: ---

Oops, actually, my path did get messed up. I didn't notice before (must be Monday), but there are several directories missing from the PATH, including the /scripts directory. So I just did another test:      /scripts/script2.rb:           #!/usr/bin/ruby           puts `env | grep PATH`           puts ENV["PATH"]           puts `/usr/bin/env | grep PATH`      Command Line:           [testing]% script2.rb           /bin:/usr/bin:/usr/local/bin:.:/scripts           /bin:/usr           PATH=/bin:/usr           [testing]% And I notice that there is no "/usr" initially, but it's there after the ENV["PATH"] is referenced. I've searched all the files in my home directory, and don't see it setting just "/usr" to the path anywhere. I also search through the files in the Ruby directory, and also never see a "/usr" by itself. ---

Hrm... I'm not sure what the equivalent is on RedHat, but what about looking /etc/csh.\* There should be default a default .cshrc and .login there, do they have any odd paths? > **···** > > On Nov 8, 2004, at 2:53 PM, Ken Innes wrote: > > > Oops, actually, my path did get messed up.

I did more testing, and found that the path is getting truncated after "/bin:/usr". My .tcshrc looked like so:      set path = ( /bin )      set path = ( $path /usr/bin )      set path = ( $path /usr/local/bin )      set path = ( $path . )      set path = ( $path /scripts ) Then I added a few lines, and it still truncated at the same spot:      set path = ( /bin )      set path = ( $path /test1/usr )      set path = ( $path /test1/usr/test2 )      set path = ( $path /usr/bin )      set path = ( $path /usr/local/bin )      set path = ( $path . )      set path = ( $path /scripts ) Gave this after executing the script:      PATH=/bin:/test1/usr:/test1/usr/test2:/usr However, it does not seem to truncate at all if put /usr as the first one:      set path = ( /usr )      set path = ( $path /bin )      set path = ( $path /usr/bin )      set path = ( $path /usr/local/bin )      set path = ( $path . )      set path = ( $path /scripts ) I really don't understand this at all.
