I would like to update WP_CLI but I don’t want to do anything stupid, is there an easy and clean way to do that?
When I check the current installed version, I have this:
wp cli version WP-CLI 2.0.1
However, the latest version of WP-CLI is 2.1.0.
And if I try to update it manually I have that back:
wp cli update Error: /usr/bin/wp is not writable by current user.
Updating it would allow me to install a different language for each of my plugins automatically (see https://github.com/wp-cli/language-command/issues/59).
