I am trying to install Crypt::Random module, a cryptographically secure random number generator, and says it requires Math::Pari 2.001802, which is not availible from cpan.org, but says it is available from this other URL, which does not work. I tried to install them both anyway and encountered this problem:

The build.log does not help me either, any other possible ways to install this module successfully? Thanks.
You will have to share the build.log file. Without that we cannot check what caused the failure.
BTW for Math::Pari you need PARI library. Starting from version 2.0, this module comes without a PARI library included.
Since you are trying to install Math-Pari-2.01080900, therefore you will first have to install PARI library.
Get it from http://pari.math.u-bordeaux.fr/download.html
If you're ok with using 32 bit Perl, you could use 32 bit Strawberry Perl, which already has both Math::Pari and Crypt::Random modules installed.
Unfortunately the 64 bit versions of Strawberry Perl do not include either of these modules. In that case, you'll have to follow the suggestion from Chankey Pathak about installing the PARI library in order to install the Math::Pari module.

I am trying to install GD and Chart to Strawberry Perl in a Windows 10 Pro PC (using CPANM). Both GD and Chart requires a dependency called ExtUtils::MakeMaker. Unfortunately MakeMaker fails to be install and I cannot tell what the error is. I hope someone can understand the error message and tell me what goes wrong.
That is how I try to install Chart and the few error message that I get:

Please let me know what goes wrong and how to fix this problem. If there is no solution to this problem, I would like to know if there is any workaround. Thanks.
UPDATE 1: I installed the latest version of Perl (5.32.1.1). Unfortunately I still cannot install the dependency MakeMaker for Chart library. The content in the build.log after trying to install Chart is:

UPDATE 2: I used the -v switch with CPANM to install Chart, and this somehow worked fine. I don't know why -v switch can make a difference. But I am glad that this works for installing Chart. Now Chart is successfully installed. Unfortunately when I try to install GD using the -v switch, I run into the same error.
The build.log of my latest attempt is the following:

Please note that the build.log mentioned in the last line above is the same build.log that I have posted right above. I don't know why it refers to itself. I mention this just in case someone wants to see the "real" build.log.
UPDATE 3: Finally with the help from Håkon Hægland, I figured out that the PATH of the computer was missing several paths (namely C:\Windows;C:\Windows\System32;C:\Windows\System32\Wbem). I added the missing paths to PATH, and the installation is successful. I have no idea why those important paths would go missing. But I am glad that the installation of GD and Chart are successful.
With the help from Håkon Hægland, I finally figured out that the PATH of the computer somehow was missing several important paths, namely C:\Windows, C:\Windows\System32, and C:\Windows\System32\Wbem. This explains the reason why CPANM failed to install GD and Chart. It probably could not get access to a command to install the distribution or its dependency. After I have added the missing paths to PATH, I have no problem using CPANM to install GD and Chart.
As of why those paths were missing from PATH, I have no idea. I don't recall this problem ever happened to me.
As of why I could use CPANM to install Chart using the -v switch despite the fact that the paths were missing, I have no idea either.

The problem with installing Crypt::Curve25519 is described in this issue. I downloaded the problematic module Crypt::Curve25519 and patched it:
git clone git#github.com:ajgb/crypt-curve25519.git
wget https://www.cpan.org/authors/id/S/SR/SREZIC/patches/Crypt-Curve25519-0.06-PR10-ANOTHERLINK.patch

How can I make cpanm use the installed patch instead (i.e. skip installation of Crypt::Curve25519 since it is already installed)?
The problem seems to be missing VERSION information in the module. By adding a line
our $VERSION = 0.06;
to the top of the file lib/Crypt/Curve25519.pm and then reinstall, and then installing cpanm Net::SSH::Perl worked fine (it accepted the patched installation and did not try to download the broken version).
Here is the patch I used to lib/Crypt/Curve25519.pm:
diff --git a/lib/Crypt/Curve25519.pm b/lib/Crypt/Curve25519.pm
index 686b706..d9c2b3d 100644

## -1,4 +1,5 ##

+our $VERSION = 0.06;
#ABSTRACT: Generate shared secret using elliptic-curve Diffie-Hellman function
use strict;
There's a few things to check:
cpanm knows where to find your patched version.
The patched version has a version that's higher than the one on CPAN. The module idea in CPAN assumes that you always want the latest, so ensure that yours is.
You don't want to install a patched module at the standard location because you don't want a cpan client to overwrite it.
Some other things that can work:
Force install the module and ignore the failures (cpanm has a --notest feature). The CPAN version is still installed, but that doesn't matter.
Have your patched version in a separate directory that's at the front of #INC so your program finds it first. This effectively hides the CPAN version.
I am using conda to install several packages. I already installed Perl under conda and is the one working in this machine (running Ubuntu 18.04). Now I am trying to use a script that requires bioperl.
I tried to update conda, install bioperl through conda AND installing bioperl through cpanm as shown below.
I checked to currently used Perl is the anaconda one. The shebang in the perl script is #!/home/evo-slave/anaconda_ete/bin/perl -w
This is the initial error while running the script

I don`t know if this is an issue of bioperl not being called/installed by the anaconda perl or during the execution of the script, maybe this lines within the script should indicate something else

UPDATE 2
This problem is coming up again in miniconda3 bioperl installs.
UPDATE
I have not experienced this error for a while with perl packages, so likely some updates occurred on the conda/package side that fixed this. I would recommend trying to update your conda and checking your conda channels before trying this kind of weird kludge.
ORIGINAL ANSWER
I am posting this as an answer not because it's a good idea, but because it provides more information. I am working on Amazon Linux so it's slightly different, but also running into issues with bioperl dependencies installed through conda. In my case I am trying to run VirSorter, which mentions this problem and proposes a solution that does not work for me, but suggests confirming that your PERL5LIB is properly set.
I observed that my perl is 5.26.2:
$ perl --version
This is perl 5, version 26, subversion 2 (v5.26.2) built for x86_64-linux-thread-multi
But conda is for some obscure reason installing my perl dependencies for 5.22.0: /home/ec2-user/anaconda3/envs/virsorter/lib/perl5/site_perl/5.22.0/:
$ ls /home/ec2-user/anaconda3/envs/virsorter/lib/perl5/site_perl/5.22.0/
Algorithm Bio Capture Class Data Devel Exception IO Sub Test Text URI URI.pm x86_64-linux-thread-multi
I found that I could get VirSorter running, apparently successfully, by simply setting PERL5LIB to the 5.22.0 lib under conda:
OLD_PER5LIB=$PERL5LIB
export PERL5LIB=/home/ec2-user/anaconda3/envs/virsorter/lib/perl5/site_perl/5.22.0/
# run virsorter
# no errors!
I am sure that this throws up a bunch of red flags for the perl people, and I'm sure that it's very fragile if it actually works at all. Perhaps the question is why conda is installing perl modules as the wrong perl version?
I found this one relevant question on problems with installing Math::Pari, here. Except this is for shell and I have cpanm. I downloaded the latest version of Pari, Pari 2-7-6. Where should I extract the files in C:\Program Files (x86)\Pari-2-7-6 to install Math::Pari in perl (not in cpan shell however) successfully? Thanks in advance.

Here is an easy way on Windows:

cd into the directory you created when extracting
perl Makefile.PL force_download <- this downloads things to the right place
dmake
dmake install
I am wondering why I get "Installing the dependencies failed: Module 'Module::Name' is not installed" even when dependency is has been installed. I am using perlbrew and cpanm. Here is an example of what happens with many modules that I try to install:

local::lib was messing stuff up. URI.pm was installed but not under the perlbrew directory.
With perlbrew you can install a perlbrew specific cpanm which facilitates installing to the various perls/ that are installed/managed using the perlbrew tool. I have found that this works very well.
However perlbrew can become confused if you mix in your own local::lib and set related environment variables like PERL5LIB, PERL_MM_OPT, PERL_MB_OPT etc. (see for example the post by #cjm in perlbrew and local::lib at the same time?). Some of these environment vars can interact and interfere with perlbrew's own environment so it's generally best to avoid mixing them or simply to let perlbrew manage the environment using its own versions of those variables.
It is of course possible to use local::lib environments "inside" perlbrew with the lib command) and to do very complicated things for testing with different perl versions, shipping an application with requirements (c.f. Carton). In my own environment I was able to manage system perl; a user installed local::lib that used the system perl; and a huge set of perlbrew perls all with judicious use of environment variables (thankfully a temporary set up while migrating between versions).
That sort of set up can get complicated very quickly, and is difficult to replicate. One of the greatest advantages of perlbrew is you can easily setup matching perl environments on multiple machines; or different perl environments on the same machine.
