“E: Unable to locate package python-pip” on Ubuntu 18.04

问题

I am trying to install virtualenv on Ubuntu.

First it said command 'pip' not found, so I typed

sudo apt install python-pip

then it said

E: Unable to locate package python-pip

I tried to reset WSL, download using cmd but it doesn't work with Ubuntu. I don't know why. Even though I have downloaded python3, virtualenv, and pip using cmd. It doesn't work with Ubuntu 18.04. It also fails on Ubuntu 14.04.

aiki@LAPTOP-886AEJJG:~$ pip

Command 'pip' not found, but can be installed with:

sudo apt install python-pip

aiki@LAPTOP-886AEJJG:~$ sudo apt install python-pip

I'm trying to install jarvis and mycroft on win 10, but I need to use Ubuntu because it only works with Linux.

回答1:

Try following command sequence on Ubuntu terminal:

sudo apt-get install software-properties-common
sudo apt-add-repository universe
sudo apt-get update
sudo apt-get install python-pip

回答2:

ls /bin/python*

Identify the highest version of python listed. If the highest version is something like python2.7 then install python2-pip If its something like python3.8 then install python3-pip

Example for python3.8:

sudo apt-get install python3-pip
