Steps To Use pip to Install Python packages on Linux
Before you start, you must have access to your server as a root or non-root user with sudo privileges. Then, follow the steps below to complete this guide.
Step 1 – Install the Latest Pip Command for all Linux Users
The pip command line tool is not installed by default on Linux distros. To install the latest pip command which is Pip 3, follow the steps below.
Install pip command on Debian / Ubuntu
On Debian-based distros, you can run the system update and use the command below to install pip:
# sudo apt update
# sudo apt install python3-pip
Install pip command on AlmaLinux / Rocky Linux / RHEL
To install pip on RHEL-based distros, you need to install Epel repo and use the commands below to install pip:
# sudo dnf update
# sudo dnf install epel-release -y
# sudo dnf install python3-pipStep 3 – Install Python Packages with Pip Command on Linux
At this point, you can use the pip command to manage your Python packages. Then, you can list all commands with pip by running the command below:
pip3 helpoutput
Usage:
pip3 <command> [options]
Commands:
install Install packages.
download Download packages.
uninstall Uninstall packages.
freeze Output installed packages in requirements format.
list List installed packages.
show Show information about installed packages.
check Verify installed packages have compatible dependencies.
config Manage local and global configuration.
search Search PyPI for packages.
cache Inspect and manage pip's wheel cache.
index Inspect information available from package indexes.
wheel Build wheels from your requirements.
hash Compute hashes of package archives.
completion A helper command used for command completion.
debug Show information useful for debugging.
help Show help for commands.
General Options:
-h, --help Show help.
--isolated Run pip in an isolated mode, ignoring
environment variables and user configuration.
-v, --verbose Give more output. Option is additive, and can be
used up to 3 times.
-V, --version Show version and exit.
-q, --quiet Give less output. Option is additive, and can be
used up to 3 times (corresponding to WARNING,
ERROR, and CRITICAL logging levels).
--log <path> Path to a verbose appending log.
--no-input Disable prompting for input.
--proxy <proxy> Specify a proxy in the form
[user:passwd@]proxy.server:port.
--retries <retries> Maximum number of retries each connection should
attempt (default 5 times).
--timeout <sec> Set the socket timeout (default 15 seconds).

whether a new version of pip is available for
download. Implied with --no-index.
--no-color Suppress colored output.
--no-python-version-warning
Silence deprecation warnings for upcoming
unsupported Pythons.
--use-feature <feature> Enable new functionality, that may be backward
incompatible.
--use-deprecated <feature> Enable deprecated functionality, that will be
removed in the future.
At this point, you can easily install your Python packages with pip. For example, we want to install the OpenStack Horizon dashboard. To do this, we can use the command below:
pip install horizonoutput

...Pip Search Command is banned by Python
At the current time, if you use the pip search command, you may get the following error:
ERROR: XMLRPC request failed [code: -32500]
RuntimeError: PyPI no longer supports 'pip search' (or XML-RPC search). Please use https://pypi.org/search (via a browser) instead. See https://warehouse.pypa.io/api-reference/xml-rpc.html#deprecated-methods for more information.
The Python developers said that they were experiencing “hundreds of thousands of search calls per hour” and the XML-RPC API had already been determined to be deprecated before this happened.
Note: You can search for the packages directly from the pypi.org site.
Conclusion
At this point, you have learned to Install the latest pip command on Linux distributions and use it to manage your Python packages. You just keep in mind that the Pip search command is deprecated. To resolve this, you can use the original site to search for your desired packages. Hope you enjoy it.
