How to change composer global vendor directory in ubuntu

Question

Something is wrong with my composer local installation.

I'm under ubuntu 22, my global vendor directory path is pointing to a project directory and not to a SO global directory, such as /home/username/.composer/vendor.

Take a look to this output

composer config --global -l

The question are: How can i change this directory path (vendor-dir and bin-dir) ? Why I am experiencing this problem? What I did wrong?

I tried to check if there is a "set" command that allows me to update this global config variables vendor-dir and bin-dir with no results.

I managed to do it using different searching keywords

As suggested here https://github.com/composer/composer/issues/4450

You can update whatever variable in your configuration (either global or local) using the following command:

composer config variable_name variable_value

hope this helps.
