Install a Perl Module — Clean & Simple Guide
Perl modules extend your server’s Perl capabilities. This guide explains how to search, install, and manage Perl modules using a simple interface.
What is a Perl Module?
A Perl module is a set of pre-written functions that can be used in your own Perl scripts. These modules are stored in repositories like CPAN and can be installed easily on your server.
Installing a Perl Module
You can install modules in two main ways:
- Install by Name: If you know the module name (like
JSON), type it in and click Install Now. - Search First: Enter a keyword (like "date" or "xml") and click Go to find available modules, then click Install.
How It Works
The system uses the CPAN client in the background to download and install the module. You don’t need to use the terminal — everything is done automatically.
Managing Installed Modules
Once installed, you can take the following actions on each module:
- Reinstall — Useful if something went wrong with the first install.
- Update — Upgrade to the latest version available.
- Uninstall — Remove the module if it's no longer needed.
- View Docs — Link to documentation on CPAN.
Install via Terminal (Optional)
Advanced users can install modules from the command line:
cpan install JSON
For bundles with dependencies:
cpan install Bundle::DBI
make or gcc. These are pre-installed on most servers.
Troubleshooting Tips
If installation fails, try the following:
- Check available disk space and RAM.
- Double-check the module name for typos.
- Review log output for error details.
- Ensure your user has permission to install modules.
Summary
- Install Perl modules by name or search.
- Manage modules: update, reinstall, or uninstall.
- Command-line install is also available.
- Documentation is easily accessible via the interface.
