Enable perl module from another location

Question

my problem is the following

• I have lib in location. / abc / def / lib
• I use it on the go. /abc/xyz/lib/tuv/abc.pm

I run the code from another place generally something like. / abc / xyz / blah 1 / blah2 /../../. I am running the code here.

I created env params

setenv def ./abc/def 
setenv xyz ./abc/xyz

I tried the following solutions

• Begin { push(@INC, $ENV{def}."/lib" ) }
  Along with providing a path for other libraries that I used, use lib $ ENV {xyz}. "/ lib"

  This solution did not work. I get an error in the library. / abc / def / lib is not included.

• I tried FindBin

  # for the libs present in ./abc/def/lib
  use FindBin;
  use lib "$FindBin::Bin/../../";
  use mylib::abc;
  use mylib::def;
  

(I tried to give a way also to the roots, where to start searching in FindBin)

I tried to use different combinations, but not sure why it is not working. Can someone point out what I'm doing wrong, or my understanding of FindBin is wrong.

Answer 1

FindBin . , $FindBin::Bin , script. , ...

use lib $FindBin::Bin . '/../../etc';

'/../..' script lib.

Answer 2

, . , " , " . , "Can not locate [some module] in @INC".

() @INC. .

• use lib
• ( shebang) -I
• PERL5LIB

@INC, .

@INC. , , @INC - use , BEGIN ( use ). , , BEGIN, BEGIN - .

, , , FindBin, , . FindBin , (, ./bin, ./lib).

, @INC (./abc/xyz/lib/tuv/abc.pm). , FindBin $FindBin::Bin . $FindBin::Bin , , .
