\"install<\/p>\n

Pip is a package manager that facilitates the installation and management of Python software packages, for instance, those contained in the Python Package Index (PyPI).<\/p>\n

In this article, I am going to show you how to install and use pip on Ubuntu 18.04.<\/p>\n

Install pip for Python3 on Ubuntu<\/h2>\n

By default, Ubuntu 18.04<\/a> comes with Python3 in its installation. To install pip3 for Python3 follow the following steps<\/p>\n

Update the system<\/h3>\n

# sudo apt-get update<\/p>\n

Install pip for python3<\/h3>\n

# sudo apt-get install python3-pip<\/p>\n

This command installs pip together with all the dependencies necessary for building python modules.<\/p>\n

Sample Output<\/p>\n

The following NEW packages will be installed:
\nlibpython3-dev libpython3.4 libpython3.4-dev python3-chardet
\npython3-colorama python3-dev python3-distlib python3-html5lib python3-pip
\npython3-requests python3-setuptools python3-six python3-urllib3
\npython3-wheel python3.4-dev
\n0 upgraded, 15 newly installed, 0 to remove and 26 not upgraded.
\nNeed to get 20.2 MB of archives.
\nAfter this operation, 38.7 MB of additional disk space will be used.
\nDo you want to continue? [Y\/n] Y<\/p>\n

Checking the version of pip3<\/h2>\n

To check the version of pip3 run the command below<\/p>\n

# pip3 –version<\/p>\n

OR<\/p>\n

# pip3 -V<\/p>\n

Output<\/p>\n

pip 8.1.1 from \/usr\/lib\/python3\/dist-packages (python 3.5)<\/p>\n

Install pip for Python2 on Ubuntu<\/h2>\n

Python2 is not installed by default on Ubuntu 18.04. If you wish to install Python2 and pip for Python 2 run the following commands<\/p>\n

Update the system<\/h3>\n

# sudo apt-get update<\/p>\n

Install pip for python2<\/h3>\n

# sudo apt-get install python-pip<\/p>\n

Checking the version of pip<\/h2>\n

To verify the installation of pip, run<\/p>\n

# pip –version<\/p>\n

OR<\/p>\n

# pip -V<\/p>\n

Output<\/p>\n

# pip 10.0.1 from \/usr\/local\/lib\/python2.7\/dist-packages\/pip (python 2.7)<\/p>\n

Using pip in package management<\/h2>\n

Now that we have seen how to install various versions of pip in different python environments, it’s time to see how we can use it to install, upgrade and uninstall packages.<\/p>\n

Installing a package with pip<\/h3>\n

When installing python modules, it’s recommended that you do so in virtual environments. a virtual environment creates an isolated environment for several python projects. This allows you to install a specific module per project without worrying about the module affecting other Python projects.<\/p>\n

To install a package with pip<\/h3>\n

# pip3 install package_name<\/p>\n

For instance<\/p>\n

# pip install numpy<\/p>\n

Output<\/p>\n

If you wish to specify installation of a specific package run,<\/p>\n

# pip3 install package_name==version no.<\/p>\n

For example<\/p>\n

# pip3 install numpy=1.15<\/p>\n
