The directory '/home/millahue/.cache/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

Answer 1

You are facing this error because you don’t have pkg-config installed which is required for your command to run. The solution is

First run this command:

sudo apt install build-essential automake pkg-config libtool libffi-dev libgmp-dev

and then

sudo apt install libsecp256k1-dev

this should solve your error.
