wp-cli error "/usr/bin/env: «mysql»: No existe el archivo o el directorio"

Question

I'm trying to use wp-cli on Ubuntu and I'm using Xampp to run WordPress, but every time I try run this command:

wp core config --dbname=demo-1 --dbuser=root --dbpass=hola --dbhost=localhost --dbprefix=wp_ --extra-php <<PHP
define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );
PHP

I get this error:

/usr/bin/env: «mysql»: No existe el archivo o el directorio

I just added: "export PATH=$PATH:/usr/bin/env/mysql" but it doesn't work.

Does anybody know how I can fix this?
