use statements and system glitch

Andrewkl · #1 (**permalink**) 07-01-2009

hi,

i have a perl script that runs as a cron job... Once in a while, the perl
script fails with:

Can't locate <module>.pm in @INC (@INC contains: .............)

because one of the perl modules specified in the "use" statements is
unavailable due to an NFS glitch.

Is there some code/logic i can put into my perl script to try to "use"
the module again in the event of an NFS glitch? Please provide an example.

Thanks

The advisable solution is to localize all includes/required modules. Having said that, you could try something like this, in place of your use:

Code:

BEGIN { 
  if (-r path-to-module)  { require module; import Module; } 
}

So what will happen if the module is unavailable? the rest of your code will probably fail to compile.
