How to update pip in python3 in aws instance ec2

Question

I applied this command

 pip install --upgrade pip

The package shows error in installing python package:

Collecting pip   
Permission denied: 

 **You are using pip version 9.0.3, however version 19.3.1 is available. You should consider upgrading via the 'pip install
 --upgrade pip' command.**

This command is not working in my aws ec2 linux terminal

Answer 1

This command should work

 python -m pip install -U pip 

If this doesn't work and you get a permission error use this

python -m pip install -U pip --user

Answer 2

In order to upgrade pip globally (ie for all users), you need sudo rights:

sudo pip install --upgrade pip

Alternatively, if you don't have sudo privileges you can still upgrade it for the current user:

pip install --upgrade pip --user
