How to Install Perl Modules on Debian Linux? – Linux Hint

Perl is a very talked-about high-level programming language. It’s a scripting language, in actual fact, whose syntax resembles carefully with C and C++. A Perl module is outlined as a group of associated capabilities. It is vitally a lot just like the idea of libraries is C++ and Java. Which means that when you intend to run a perform in Perl, you will need to have the respective module for that perform put in in your system. That’s the reason on this article, we shall be studying the strategy of putting in Perl modules on Debian 10.

Technique of Putting in Perl Modules on Debian Linux:

For putting in Perl modules on Debian 10, you’ll have to undergo all of the steps listed beneath:

Step # 1: Putting in Perl on Debian 10:

To begin with, that you must have Perl put in in your Debian 10 system. For that, you’ll launch the terminal in Debian 10 by searching for it within the Actions menu. The Debian 10 terminal might be seen within the following picture:

Now you must run the next command in your terminal to put in Perl in your Debian 10 system:

As soon as the set up of Perl completes efficiently, the output proven within the picture beneath shall be displayed in your Debian 10 terminal:

Step # 2: Updating System Cache:

Earlier than putting in Perl modules, you might be suggested to replace your system’s cache with the next command:

As soon as all of the required packages and dependencies have been up to date, it is possible for you to to witness the next output in your Debian 10 terminal:

Step # 3: Putting in CPAN on Debian 10:

One of the simplest ways of putting in Perl modules on Debian 10 is through the CPAN repository. For doing so, we first want to put in this repository on our Debian 10 system, which might be executed with the below-mentioned command:

Through the set up of the CPAN repository, that you must sort “Y” in your terminal for carrying on with its execution as highlighted within the following picture:

As soon as the CPAN repository has been efficiently put in in your Debian 10 system, the terminal will produce the output proven within the picture beneath:

Step # 4: Launching and Configuring the CPAN Interactive Shell:

For putting in Perl modules with CPAN, you first must launch and configure the CPAN interactive shell, which might be executed just by operating the next command in your terminal:

cpan

As quickly as you attempt to launch the CPAN interactive shell with the above-mentioned command, you can be requested to configure it. You must sort in “sure” after which press the Enter key as highlighted within the picture proven beneath:

After doing this, you can be requested to decide on an strategy with which you wish to set up your modules. The strategy chosen by default is “[local: lib],” and it’s also the really useful strategy. Due to this fact, for choosing this strategy, you merely must press the Enter key, as proven within the following picture:

It should take a number of seconds for the automated configuration technique of CPAN to finish, after which the CPAN interactive shell will seem in your display as proven within the picture beneath:

Step # 5: Putting in Perl Modules through CPAN on Debian 10:

Now you’ll be able to go to the next website: http://www.cpan.org/modules/index.html to search for any module of your selection that you just wish to set up. After selecting a module to put in, you might be purported to run the next command in your CPAN interactive shell:

Right here, you must exchange ModuleName with the identify of the particular module that you just wish to set up through CPAN in your Debian 10 system. For the sake of demonstration, we shall be putting in the MIME: Lite module, as proven within the picture beneath:

As soon as the specified module has been put in in your Debian 10 system, your CPAN interactive shell will look one thing like proven within the following picture. In the identical method, you can too set up some other Perl module of your selection. As soon as you might be executed with the set up, and also you wish to return to your common terminal, you’ll be able to merely sort the “exit” command adopted by urgent the Enter key to modify out of your CPAN interactive shell to your Debian 10 terminal as proven within the following picture:

Conclusion:

By utilizing the easy methodology described on this article, one can simply set up as many Perl modules as he needs or in accordance with his necessities. On this method, you can be all set to create Perl scripts from very primary to extraordinarily complicated.
