'How to Install pip for python 3.7 on Ubuntu 18?

I've installed Python 3.7 on my Ubuntu 18.04 machine. Following this instructions in case it's relevant:

Download : Python 3.7 from Python Website [1] ,on Desktop and manually unzip it, on Desktop Installation : Open Terminal (ctrl +shift+T)
Go to the Extracted folder
$ cd ~/Desktop/Python-3.7.0

$ sudo make install
Making Python 3.7 default Python :
$ sudo vim ~/.bashrc
press i
on the last and new line - Type
alias python= python3.7

:wq
now type
$ source ~/.bashrc

I've downloaded several modules through pip install module but when I try to import them, I get a ModuleNotFoundError: No module names 'xx'

So I did some research and apparently when used pip to install, it installed in the modules in previous version of Python. Somewhere (probably a question in SO) I found a suggestion to install the module using python3.7 -m pip install module but then I get /usr/local/bin/python3.7: no module named pip.

Now I'm stuck, pip is installed, but apparently not for Python 3.7. I'm assuming that if I can install pip for Python 3.7, I can run the pip install command and get the modules I need. If that is the case, how can I install pip for python 3.7, since it's already installed?

This is the best I have come up with:

I have installed python 3.7 successfully and I can install modules using pip (or pip3) but those modules are installed in Python 3.6 (Comes with ubuntu). Therefore I can't import those modules in python 3.7 (get a module not found)

Python 3.7 doesn't recognize pip/pip3, so I can't install through pip/pip3 I need python 3.7

python ubuntu pip

A quick add-on to mpenkov's answer above (didn't want this to get lost in the comments)

For me, I had to install pip for 3.6 first

sudo apt install python3-pip

now you can install python 3.7

sudo apt install python3.7

and then I could install pip for 3.7

python3.7 -m pip install pip

and as a bonus, to install other modules just preface with

python3.7 -m pip install <module>

EDIT 1 (12/2019):

I know this is obvious for most. but if you want python 3.8, just substitute python3.8 in place of python3.7

EDIT 2 (5/2020):

For those that are able to upgrade, Python 3.8 is available out-of-the-box for Ubuntu 20.04 which was released a few weeks ago.

This works for me.

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

Then this command with sudo:

python3.7 get-pip.py

Based on this instruction.

I used apt-get to install python3.7 in ubuntu18.04. The installations are as follows.

install python3.7

sudo apt-get install python3.7

install pip3. It should be noted that this may install pip3 for python3.6.

sudo apt-get install python3-pip

change the default of python3 for python3.7. This is where the magic is, which will make the pip3 refer to python3.7.

sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.7 1

Hope it works for you.

To install all currently supported python versions (python 3.6 is already pre-installed) including pip for Ubuntu 18.04 do the following:

To install python3.5 and python3.7, use the deadsnakes ppa:

sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt-get update
sudo apt-get install python3.5
sudo apt-get install python3.7

Install python2.7 via distribution packages:

sudo apt install python-minimal  # on Ubuntu 18.04 python-minimal maps to python2.7

To install pip use:

sudo apt install python-pip  # on Ubuntu 18.04 this refers to pip for python2.7
sudo apt install python3-pip  # on Ubuntu 18.04 this refers to pip for python3.6
python3.5 -m pip install pip # this will install pip only for the current user
python3.7 -m pip install pip

I used it for setting up a CI-chain for a python project with tox and Jenkins.

Solution 5:^[5]

Combining the answers from @mpenkon and @dangel, this is what worked for me:

sudo apt install python3-pip
python3.7 -m pip install pip

Step #1 is required (assuming you don't already have pip for python3) for step #2 to work. It uses pip for Python3.6 to install pip for Python 3.7 apparently.

Solution 6:^[6]

When i use apt install python3-pip, i get a lot of packages need install, but i donot need them. So, i DO like this:

apt update
apt-get install python3-setuptools
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python3 get-pip.py
rm -f get-pip.py

Solution 7:^[7]

The following steps can be used:


sudo apt-get -y update
---------
sudo apt-get install python3.7
--------------
 python3.7
-------------
 curl -O https://bootstrap.pypa.io/get-pip.py
-----------------
sudo apt install python3-pip
-----------------
sudo apt install python3.7-venv
-----------------
 python3.7 -m venv /home/ubuntu/app
-------------
 cd app   
----------------
 source bin/activate

Install python pre-requisites

sudo apt update
sudo apt install build-essential zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libreadline-dev libffi-dev wget

Install python 3.7 (from ppa repository)

sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt update
sudo apt install python3.7

Install pip3.7

sudo apt install python3-pip
python3.7 -m pip install pip

Create python and pip alternatives

sudo update-alternatives --install /usr/local/bin/python python /usr/bin/python3.7 10
sudo update-alternatives --install /usr/local/bin/pip pip /home/your_username/.local/bin/pip3.7 10

Make changes

source ~/.bashrc
python --version
pip --version

Solution 9:^[9]

For those who intend to use venv:

If you don't already have pip for Python 3:

sudo apt install python3-pip

Install venv package:

sudo apt install python3.7-venv

Create virtual environment (which will be bootstrapped with pip by default):

python3.7 -m venv /path/to/new/virtual/environment

To activate the virtual environment, source the appropriate script for the current shell, from the bin directory of the virtual environment. The appropriate scripts for the different shells are:

bash/zsh – activate

fish – activate.fish

csh/tcsh – activate.csh

For example, if using bash:

source /path/to/new/virtual/environment/bin/activate

Optionally, to update pip for the virtual environment (while it is activated):

pip install --upgrade pip

When you want to deactivate the virtual environment:

deactivate

Solution 10:^[10]

I installed pip3 using

python3.7 -m pip install pip

But upon using pip3 to install other dependencies, it was using python3.6.
You can check the by typing pip3 --version

Hence, I used pip3 like this (stated in one of the above answers):

python3.7 -m pip install <module>

or use it like this:

python3.7 -m pip install -r requirements.txt

I made a bash alias for later use in ~/.bashrc file as alias pip3='python3.7 -m pip'. If you use alias, don't forget to source ~/.bashrc after making the changes and saving it.

Solution 11:^[11]

How about simply

add-apt-repository ppa:deadsnakes/ppa
apt-get update
apt-get install python3.7-dev
alias pip3.7="python3.7 -m pip"

Now you have the command

pip3.7

separately from pip3.

Solution 12:^[12]

curl https://bootstrap.pypa.io/get-pip.py | sudo python3.7

if all else fails.

Solution 13:^[13]

pip3 not pip. You can create an alias like you did with python3 if you like.
