If you need to downgrade your Perl version, here’s a step-by-step guide to help you through the process. This guide assumes you're using a Unix-like system and have some familiarity with the command line.
Downgrading Perl
1. Uninstall Current Perl Version
If you've installed Perl via Homebrew, you can uninstall it using:
brew uninstall perl
If Perl was installed manually or through another package manager, follow the corresponding uninstallation steps for that method.
2. Install the Desired Perl Version
You can install a specific Perl version using various methods:
Using Homebrew:
Homebrew typically manages the latest versions, but you can use it to install a specific version if available. If not directly available, consider installing it manually or through other methods.
brew install perl@5.26
Using Perlbrew:
perlbrew is a tool for managing multiple Perl versions. You can install it via cpanm:
cpanm App::perlbrew
Then, install the desired Perl version using perlbrew:
Replace 5.26.2 with your desired version. Ensure that you have the necessary dependencies and development tools installed.
3. Verify the Installation
After installation, check the Perl version to confirm:
perl -v
It should display the version you've just installed.
4. Update Environment Variables
If you’ve manually installed Perl or if it's installed in a non-standard location, you might need to update your PATH environment variable. For example:
export PATH=/path/to/your/perl/bin:$PATH
You can add this line to your shell’s profile file (like ~/.bashrc or ~/.zshrc) to make the change permanent.
5. Reinstall Perl Modules
After downgrading Perl, you might need to reinstall any Perl modules for the new version. Use cpan or cpanm to reinstall the required modules.
