I'm getting the following error from Perl. Am I doing something wrong or should I report it?
Can't locate object method "_process_isa_option" via package
"Class::MOP::Attribute" at
/home/martin3/perl5/lib/perl5/x86_64-linux-gnu-thread-multi/Moose/Meta/Attribute.pm
line 207.
This is in trying to (re)install Catalyst::Runtime using cpanm.
My code used to be working, but Perl was upgraded and I am trying to get it working again.
This bug report shows what the problem is. Looks like you've updated some of your dependencies from the Moose::* namespace, but not all of them.
If you run moose-outdated on your command line, then it will tell you which modules you need to update.

I am working on Perl, and when I run my script I got the error said :
Can't locate XML/Simple.pm in #INC
You're already getting help in comments for getting CPAN installs working correctly, but most common Perl modules can also be installed from the Ubuntu repositories. In this case, you should also be able to sudo apt-get install libxml-simple-perl to install it from Ubuntu. If that's not the correct package name (I use Debian rather than Ubuntu, so it's possible Ubuntu may have renamed it), you can use apt-cache search XML::Simple to get a list of matching packages, then check their details with apt-cache show [package name] to determine which is the one you want.
Note, however, that the XML::Simple documentation advises "You really don't want to use this module in new code." If you are writing new code, you should probably look into another XML module. I personally use XML::Twig, which happens to offer a simplify method which produces output very much like that from XML::Simple, although you're probably better off getting used to the more robust node-based interface.
Running the Twitter Application in Perl and facing the above mentioned problem. The Perl is 5.8.8 and system is AIX with no root access.

I realize this is an ancient post, but it's high on google, so this advice may eventually reach someone who can use it.
I was fighting with a similar issue, and it turned out my perl distribution did not include integer.pm (part of the distro) and I fixed said bug.
To check if this, or something similar, causes problems in your case, run this script:
#!/usr/bin/env perl
use Digest::HMAC_SHA1;
And check what it fails on.
I'm trying to install some perl modules as part of the set up for Circos. I'm installing the modules using cpan in terminal, and while the initial set up seems to go well, all the modules fail during the final step of the install, when the Makefile is being written.
Here's what the error looks like:
Checking if your kit is complete...
Looks good
Writing Makefile for Font::TTF

I think the only option might be to manually install the modules instead of using cpan, but I figured it might be worth a shot to put up a question here.
It seems that /System/Library/Perl/5.12/CPAN/Distribution.pm is trying to find your system's "make" command. Since you're using Mac OS/X is "make" actually installed or do you need to add some developer tools?
To further on G. Cito's answer/question:
This old answer might do the trick for you, if you're on Mac OS/X, as the exact same error is thrown in the respective circumstances:

I have downloaded strawberry PERL and writing one application with CGI Perl Apache on Winxp sp3).
One of the libraries (written by someone else) which I using uses XML::LibXML. When i load the page it gives Internal Server Error. From Apache error log i can see this error:
Can't load 'C:/strawberry/perl/site/lib/auto/XML/LibXML/LibXML.dll' for module XML::LibXML: load_file:The specified module could not be found at C:/strawberry/perl/lib/DynaLoader.pm line 190.
C:/strawberry/perl/site/lib/auto/XML/LibXML/LibXML.dll exists with all permissions.
Also this library works properly on Linux. My application also works fine if I remove all code that needs LibXML.
Can anyone tell me when can be possible issue here.
If you peek into the source for DynaLoader you'll find
Many dynamic extension loading problems will appear to come from
this section of code: XYZ failed at line 123 of DynaLoader.pm.
Often these errors are actually occurring in the initialisation
C code of the extension XS file. Perl reports the error as being
in this perl code simply because this was the last perl code
it executed.
You should have also gotten (but may not have noticed) the following dialog, which provides a more accurate error message:
The problem isn't that perl can't find LibXML.dll; it's that LibXML.dll can't find the real libxml. (The former is just a wrapper that provides Perl bindings for the latter.) To fix that you need to ensure that Strawberry Perl's c\bin folder is in your PATH. In your case, that would be C:\strawberry\c\bin.
You might have to check the environment variable settings in the windows,
make sure that the installation path of the module is present in the PATH variable.
The reason it works in linux is that make files usually set the environment variables for you in linux in windows it may not have set properly.
For eg;
go to Control Panel\System and Security\System click change settings then advanced tab in user variable section see if there is a variable called perl5lib.
if not create an new perl5lib variable and add the path of your library ( usuall C:\Perl\site\lib but may be different in your case)
I had the same issue after installing Strawberry perl. It was working fine when I run the script from server, but not remotely from a automation tool. The issue was because of the Environment variables not updated when we run it remotely. So I did server reboot, which resolved the issue.
I encountered the same problem recently, in my case it was not related to PATH variable (it was already correct). The thing is I was executing my script from Git Bash console and as it turned out git-bash perl was being used instead of Strawberry (see git-bash perl should not be first in path). Switching to standard Windows CMD terminal helped.
I'm trying (desperately) to build / install the newest version of WWW::Curl onto my activeperl box (I'll explain in a moment why I don't use the PPM)
I had to make some modifications as per the instructions found here:
http://cpansearch.perl.org/src/SZBALINT/WWW-Curl-4.15/README.Win32
I also had to change the following line:
From:
open(H_IN, "-|" "gcc", "$curl_h") and $has_cpp++;
To:
open(H_IN, "gcc $curl_h") and $has_cpp++;
I finally got perl Makefile.PL to work but now, when I run nmake, I get the following:
Missing right curly or square bracket at -e line 1, at end of line
Execution of -e aborted due to compilation errors.
NMAKE: fatal error U1077: 'C;|windows\system32\cmd.exe' : return code '0xff'
Stop.
Now, the reason I'm trying to compile this rather than using the PPM supplied by u.winnipeg is because the that PPM doesn't seem to support SSL transaction (I get "libcurl: ssl disabled") Now, if anyone can show me how to get ssl to run on this PPM, I'm more than happy to use it.
Thank you very much in advance
I presume the original was
open(H_IN, "-|", "gcc", "$curl_h")
The reason you have to change that in because noone got around to implementing feature in Windows. Change it to
open(H_IN, qq{gcc "$curl_h" |})
Use the right name and syntax for your compiler.
Well, I finally figured it out, thanks to everyone who responded. There were a bunch of things I had to change.
Using http://cpansearch.perl.org/src/SZBALINT/WWW-Curl-4.15/README.Win32 as a guide:
The open cmd as I did above worked fine. However, I did use the advice returned by ikegami, reinierpost, and mob.
Using nmake /n (as advised by socket puppet), it printed out all of the perl statements which were being executed. I took this output and placed it into a .bat file and corrected the perl syntax.
I changed all instances of
pm_to_blib({{#ARGV}
to
pm_to_blib({#ARGV}
(it is disturbing these were returned)
Then, I had to link the libcurl libraries to each line instantiating g++, which were not linked correctly. After I added these references, everything else went smoothly.
These were added:
C:\lc\curl\lib\libcurl.a C:\lc\curl\lib\libcurldll.a
Now, WWW::Curl is happily running on my system.
As for using the PPM version, it is exactly because of SSL I had to upgrade. The newest version of WWW::Curl is 4.15 the ppm version is (I believe) 3.02.
First, many people don't know that you can use ppm to install MinGW to use cpan to install modules.
Second, if the libcurl provided by your module doesn't do SSL, you can try and replace it with a suitable SSL version from the download page. This might well fail, but you might also be lucky.
