How To Fix rxrx: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu rxrx is provided by libregexp-debugger-perl package.

libregexp-debugger-perl is:

Regexp::Debugger is a module that helps tame unruly regexes by providing live interactive run-time visualizations of any regex in a Perl code. The debugger allows one to track capture variables, follow recursive subpattern matches, set break-points within a regex match, and even step backwards through the matching process to work out exactly where things started going so horribly wrong.

When you load this module, any regex in the same lexical scope will be visually (and interactively) debugged as it matches.

In addition to the Perl module, the package also contains the module’s commandline frontend rxrx.

To fix this problem, we can install more using the command below.

sudo apt-get -y install libregexp-debugger-perl

This command might take some time to finish depending on your machine internet connection.

You can also use apt command to install libregexp-debugger-perl.

sudo apt -y install libregexp-debugger-perl

sudo aptitude install libregexp-debugger-perl
