Equivalent of pip install modern for Debian-like systems in Python 3

In this article, we will discuss how to install Python 3 packages on Debian-like systems (such as Ubuntu, Linux Mint, etc.) using pip, without the need for Docker installations. We will cover the key concepts of Python packaging and distribution, with subtitles and detailed explanations.

Installing pip for Python 3

Before we can install packages using pip, we need to make sure that pip is installed for Python 3. On Debian-like systems, we can use the following command to install pip:

This command will install the pip package manager for Python 3 on your system.

Finding the package name

The first step in installing a Python package using pip is to find the package name. Many Python packages can be found on the Python Package Index (PyPI) web site. You can search for packages on PyPI by visiting https://pypi.org and using the search bar at the top of the page.

Once you have found the package you want to install, you need to find the package name. This can usually be found in the package description, underneath the package name. For example, if we want to install the changedetection.io package, we can see from the package description that the package name is changedetection.io.

Installing the package

To install the package, we can use the pip install command followed by the package name. For example, to install the changedetection.io package, we would use the following command:

This command will download and install the changedetection.io package on your system. You can verify that the package is installed by checking the output of the pip freeze command:

This command will list all of the packages installed on your system.

Upgrading a package

To upgrade a package, we can use the pip install command followed by the package name and the --upgrade flag. For example, to upgrade the changedetection.io package, we would use the following command:

This command will download and install the latest version of the changedetection.io package on your system, replacing the current version.

Uninstalling a package

To uninstall a package, we can use the pip uninstall command followed by the package name. For example, to uninstall the changedetection.io package, we would use the following command:

This command will remove the changedetection.io package from your system.

In this article, we have discussed how to install, upgrade, and uninstall Python packages on Debian-like systems using pip. We have covered the key concepts of Python packaging and distribution, including finding the package name, installing the package, and managing packages.
