Answer 1

Try python3 -m pip3 install -r requirements.txt

If pip3 isn't found, it seems you need to install pip/pip3.

Answer 2

Link your python with the pip package manager :

After activating the virtual Environment run the below commands.

For Windows :

python3 -m ensurepip

For Linux :

sudo apt-get install python3-pip
