How To Install Pip on CentOS 8 / RHEL 8 | Holhol24

0

Pip (Pip Installs Packages) is a package management system that allows you to install
Python software packages. It installs python packages listed in the
Python Package Index (PyPI).

Pip Versions

There are two versions of Pip available for
CentOS 8 /
RHEL 8.

In this post, we will see how to install both versions of
Pip on
CentOS 8 /
RHEL 8.

Apart from the Pip installation, we will also see how to manage Python packages using Pip.

Install Pip for Python 3

Pip for Python 3 (pip3) is provided by Python 3 package. You can install it using the below command.

dnf install -y python3
Output:

Use the below command to verify the Python version.

python2 --version
Output:

Python 2.7.16

The above output shows that the system has Python 2 installed.

Check the Pip version as well.

pip2 --version
Output:

pip 9.0.3 from /usr/lib/python2.7/site-packages (python 2.7)

The above output confirms that the pip for Python 2 is successfully installed. The pip version may vary depending on the operating system and the date of release.

How to Use Pip

We will go through some basics of Pip commands.

Replace pip3 with pip2 in your commands if you are using Python 2.

Install Packages Using Pip

To install a package using Pip, you can use the below command.

pip3 install PACKAGE_NAME

For example, to install the latest version of IPython package, a powerful interactive Python shell, use the below command.

pip3 install IPython

The above command will download all the necessary files and install the specified package.

To install a specific version of the package (Example 6.0), you can use the below command.

pip3 install IPython==6.0

List Installed Pip Packages

To list the installed Python packages, use the below command.

pip3 list
Output:

.       .       .

gpg (1.10.0)
idna (2.5)
iniparse (0.4)
ipython (7.13.0)
ipython-genutils (0.2.0)
jedi (0.16.0)
netifaces (0.10.6)
parso (0.6.2)

.      .       .

Upgrade Package Using Pip

To upgrade a package to the latest version, use the below command.

pip3 install --upgrade IPython

Remove Package Using Pip

If you want to remove a package installed via pip, you can use the below command.

pip3 uninstall IPython

Search Packages using Pip

Pip’s search functionality lets you search for packages (name). This command will get the packages list from the
PyPI (Python Package Index).

pip3 search google
Output:

google (2.0.2) - Python bindings to the Google search engine.
oauthkit-google (0.1.2) - OAuthKit for Google
bits-google (1.8.6) - BITS Google
google-gax (0.16.0) - Google API Extensions
google-finance (0.1.0) - Google Finance API
google-oauth (1.0.1) - OAuth2 for Google APIs
google-auth (1.6.3) - Google Authentication Library

.     .     .

Conclusion

That’s All. I hope you have learned how to install
Pip on
CentOS 8 /
RHEL 8 and its command syntax to manage Python packages. You can visit
Pip’s user guide page for more information about Pip.
