How to enable python in lighttpd manjaroOS?

Good afternoon friends of stackoverflow I have a giant doubt I would like to be able to enable on my server lighttpd python and if possible ruby to be able to study and perform web tests from flask and django.

Here is my configuration code. Postdata to give me a test file to run on my server.

    server.port     = 80
server.username     = "http"
server.groupname    = "http"
server.document-root    = "/usr/share/www/"
server.errorlog     = "/var/log/lighttpd/error.log"
dir-listing.activate    = "enable"
index-file.names    = ( "index.html" )

mimetype.assign     = (
                ".html" => "text/html",
                ".txt" => "text/plain",
                ".css" => "text/css",
                ".js" => "application/x-javascript",
                ".jpg" => "image/jpeg",
                ".jpeg" => "image/jpeg",
                ".gif" => "image/gif",
                ".png" => "image/png",
                "" => "application/octet-stream"
            )

cgi.assign                 = ( ".pl"  => "/usr/bin/perl",
                               ".cgi" => "/usr/bin/perl",
                               ".rb"  => "/usr/bin/ruby",
                               ".erb" => "/usr/bin/eruby",
                               ".py"  => "/usr/bin/python",
                               ".php" => "/usr/bin/php-cgi" )
index-file.names           += ( "index.pl",   "default.pl",
                               "index.rb",   "default.rb",
                               "index.erb",  "default.erb",
                               "index.py",   "default.py",
                               "index.php",  "default.php" )
