This article focuses on "how to install and run Python applications in an isolated environment". Interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Let the editor take you to learn how to install and run Python applications in an isolated environment.

Install Pipx

The Python 3.6 +, Pip, and venv modules are required to install pipx. Be sure to install them as described in the following guide.

How to use Pip to manage Python packages

Here, venv is needed to create a virtual environment.

Next, run the following command to install Pipx.

$python3-m pip install-- user pipx$ python3-m userpath append ~ / .local/bin

The default location for pipx binaries is ~ / .local / bin. You can override it with the PIPX_BIN_DIR environment variable. If you want to override PIPX_BIN_DIR, just run userpath append $PIPX_BIN_DIR and make sure it's in your path.

The default virtual environment location for Pipx is ~ / .local / pipx. This can be overridden with the environment variable PIPX_HOME.

Let's move on to how to install Python applications using Pipx.

Use Pipx to install and run Python applications in an isolated environment

Here are a few examples of getting started with Pipx

Install the Python package

To install Python applications, such as cowsay, globally, run:

$pipx install cowsay

This command automatically creates a virtual environment in which the package is installed and the executable file for the package is placed in $PATH.

Sample output:

Installed package cowsay 2.0.3, Python 3.6.8These binaries are now globally available- cowsaydone! ✨? ✨

Install the Python application using Pipx

Let's test the newly installed cowsay program:

one

Here, I have extracted these examples from the official website. You can install / test any other Python package.

List Python packages

To list all installed applications using Pipx, run:

$pipx list

Sample output:

Venvs are in / home/sk/.local/pipx/venvsbinaries are exposed on your $PATH at / home/sk/.local/binpackage cowsay 2.0.3, Python 3.6.8-cowsay

If you have not installed any packages, you will see the following output:

Nothing has been installed with pipx? Upgrade package

To upgrade the package, simply do the following:

$pipx upgrade cowsay

To upgrade all installed packages at once, use:

$pipx upgrade-all runs the application from the temporary virtual environment

Sometimes, you may want to run a specific Python program, but do not actually install it.

$pipx run pycowsay moooo

Running Python applications in a temporarily isolated virtual environment

This command does not actually install the specified program, but runs it from a temporary virtual environment. You can use this command to quickly test the Python application.

You can even run the .py file directly.

$pipx run https://gist.githubusercontent.com/cs01/fa721a17a326e551ede048c5088f9e0f/raw/6bdfbb6e9c1132b1c38fdd2f195d4a24c540c324/pipx-demo.pypipx is working! Uninstall the package

You can uninstall the package using the following command:

$pipx uninstall cowsay

To delete all installed packages:

$pipx uninstall-all gets help

To view the help section, run:

$pipx-help

That's it. If you are always looking for a secure, convenient and reliable program to install and run Python applications, Pipx may be a good choice.

At this point, I believe you have a deeper understanding of "how to install and run Python applications in an isolated environment". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
