Dezi::App installation error

[raja raja]

Hi,

While installing Dezi::App, I see this error. I use Ubuntu 16.04.4 LTS. Though I tried reinstalling List::Util, I get the same error. Strange thing is that cpanm shows Dezi::App installed as correctly. Any suggestions?

I have had this same problem in the past, and it usually came down to multiple
versions of Perl and multiple @INC paths.

The first line of the deziapp script is

#!/usr/bin/env perl

which will use whatever perl binary is first in your PATH.

Try:

% which perl

and

% perl -V

and

% perl -e 'use List::Util 1.45'

to help diagnose how your system is set up. My guess is that the perl at

/home/user1/perl5/perlbrew/perls/perl-5.24.0/bin/perl

is not first in your PATH (the same as the output of "which perl").

[raja raja]

Thank you Peter. Below are config details.

I tried changing the PATH, but I still get the same error when I run 'deziapp' command.
export PATH=/home/user1/perl5/perlbrew/perls/perl-5.24.0/bin/perl:$PATH

One other thing, unlike Dezi::App, when I install 'Dezi', it seems to install and run perfectly alright.

That should be:

export PATH=/home/user1/perl5/perlbrew/perls/perl-5.24.0/bin:$PATH

i.e. you include the directory in PATH, not the full command name.

However, based on the "which perl" output, I don't think the PATH is your problem.

The first line of the "dezi" command in source is

#!/usr/bin/perl

which IIRC cpan will update to the full path of the actual perl binary when it
is installed.

That's different than "deziapp". I should probably make them the same, so that
at least it will fail consistently.

Again, I suspect you have multiple versions of Perl on this system, and the @INC
is being evaluated differently.

Try editing the deziapp and dezi files to include this line just after the first
shebang line:

die $^X;

and then trying invoking each. They should die with the full path of the Perl
binary which invoked them.

This same error has happened to me in the past, and inevitably it turned out
that an include path somewhere was mistaken. Not your fault.

The quick fix is likely to hardcode the deziapp shebang line to be identical to
whatever dezi is.

that last line makes me think that the env perl is not what is invoking deziapp.

pek

[raja raja]

Thanks Peter. I did some more tests:

Shebang line in both files (dezi and deziapp) is the same, i.e.:
#!/home/user1/perl5/perlbrew/perls/perl-5.24.0/bin/perl

Here is what I did:

I added 'die $^X;' after the first shebang line in file: /home/user1/perl5/perlbrew/perls/perl-5.24.0/bin/dezi . This is the output that I get as a result:

% dezi
/home/user1/perl5/perlbrew/perls/perl-5.24.0/bin/perl at /home/user1/perl5/perlbrew/perls/perl-5.24.0/bin/dezi line 2.

When I remove 'die $^X;' from the dezi file, dezi works normal as expected.


I then updated Dezi::App to the latest version: Dezi-App-0.016

I added 'die $^X;' after the first shebang line in file: /home/user1/perl5/perlbrew/perls/perl-5.24.0/bin/deziapp, and here is what I get:

#!/home/user1/perl5/perlbrew/perls/perl-5.24.0/bin/perl
die $^X;

#Before adding 'die $^X;':

This file is being read by the system since last and second-last line in the error output above, we have 'line 7' changed to 'line 8'.

When I remove '/perl' from the shebang line in deziapp as (with 2nd line as 'die $^X;'):
#!/home/user1/perl5/perlbrew/perls/perl-5.24.0/bin
die $^X;

I get the following output:

I also checked where List::Util 1.45 is installed by cpanm, here is the result:

Ok, that's good. That means the same interpret should be used.

I forgot that 'die' is happening *after* the "use List::Util" is evaluated, so
by then it's too late to catch the error.

what about:

% find /home/user1/perl5/perlbrew/perls/perl-5.24.0/ -name Util.pm | grep List

I'll bet you get 2 results from that.

[raja raja]

Yes Peter, you are right, here is the result. I am not sure why cpanm is installing the List::Util in two places. I thought I just installed perl 5.24 using perlbrew with regular defaults and just used cpanm to install modules.

% find /home/user1/perl5/perlbrew/perls/perl-5.24.0/ -name Util.pm | grep List

/home/user1/perl5/perlbrew/perls/perl-5.24.0/lib/site_perl/5.24.0/x86_64-linux/List/Util.pm
/home/user1/perl5/perlbrew/perls/perl-5.24.0/lib/5.24.0/x86_64-linux/List/Util.pm

How can I resolve this situation? Should I remove site_perl directory in the first path (/home/user1/perl5/perlbrew/perls/perl-5.24.0/lib/site_perl/)?

Thanks much!

I would remove the older version.

fwiw, this happened to me too several months ago, using normal 'cpan' and a
locally compiled Perl, on OS X. So I don't think it's a problem with cpanm or
perlbrew.

[raja raja]

Yessss, that worked...:)! deziapp works now.

The older version of List::Util was at '/home/user1/perl5/perlbrew/perls/perl-5.24.0/lib/5.24.0/x86_64-linux/List/Util.pm'. So, I deleted 'List' folder in /home/user1/perl5/perlbrew/perls/perl-5.24.0/lib/5.24.0/x86_64-linux/ .

cpanm and perlbrew have worked like charm in all my cases: may be I did some mistake somewhere in their installation which created these two different paths in '/home/user1/perl5/perlbrew/perls/perl-5.24.0/lib/' folder:

> site_perl/5.24.0/x86_64-linux/List/Util.pm
> 5.24.0/x86_64-linux/List/Util.pm

Thanks a lot, Peter!
