Where is pip config file on Ubuntu 20.04.2 LTS?

I have searched everywhere and I can not find the config file on Ubuntu Ubuntu 20.04.2 LTS with only pip3 installed do I have to make one? The below commands return null:

locate pip.conf

or

locate pip3.conf

or

find pip3.conf

returns

find: ‘pip3.conf’: No such file or directory

The default locations are ...

$HOME/.config/pip/pip.conf
/etc/pip.conf

Beware that there was a bug in pip 20.0 (used in Ubuntu 20.04) and fixed in pip 21.0 where it ignored the global and used

/etc/xdg/pip/pip.conf

locate pip.conf 

only works after a sudo updatedb was performed since you installed it (happens automatically at a given interval but it is not real time).

If there is no default you can create it with ...

export PIP_CONFIG_FILE=/dir/to/pip.conf

or by just creating

~/.config/pip/pip.conf

See the documentation for more information.

You can run the following command which will give you the location of the different files:

pip config -v list
