open3: exec of failed at perl 5.18.2

Question

I wrote perl script for zipping the files with Archive::SevenZip module.

I got this error

open3: exec of 7z -y -bd l -slt "Filelocation" failed at /usr/local/share/perl/5.18.2/Archive/SevenZip.pm.

I can't able to resolve that.

How we could help without seeing of _your_ code? See: [mcve] (But, guessing - try replace the `Filelocation` with some actual path). — clt60, Jan 05 '18 at 13:10

Archive::SevenZip is using open3 to execute the command-line utility 7z. That message indicates the call to exec is failing.

Most likely problem: 7z isn't installed on your machine.

If you think that's not the problem,

Replace

exec @cmd or do {
    carp "$Me: exec of @cmd failed";

with

exec @_ or do {
    local($")=(" ");
    croak "$Me: exec of @_ failed: $!";
};

(This change is already present in newer versions of IPC::Open3.)

I checked the changes are already in my system. i installed 7z in my machine."Unexpected line in 7zip output, hope that's OK: [] at /usr/local/share/perl/5.18.2/Archive/SevenZip.pm line 256, line 7." still got this error. And the line in the file is "if( $output[0] =~ /^----------\s*$/ ) { shift @output; } else { warn "Unexpected line in 7zip output, hope that's OK: [$output[0]]"; };" – keeru Jan 06 '18 at 17:54
Re "*I checked the changes are already in my system*", The error message you posted in the OP shows otherwise. You have have used the `perldoc` that was installed by a different `perl` then the `perl` used when you obtained the error message. – ikegami Jan 06 '18 at 19:50
The warning you are now asking about indicates that `7z` provided different output than expected. – ikegami Jan 06 '18 at 19:52
