venv all serves the same purpose, isolating your third party packages installed by Python package manager
pip in a virtual environment, separated from your system level Python dependencies.
But they have certain set of differences in terms of the way how they store your environments and also the speed at which they complete the task for you.
It is the by far the most used virtual environment tool to manage your pip packages in an isolated environment.
It works by installing a bunch of files in a directory (e.g.
env/), and then modifying the PATH environment variable to prefix it with a custom bin directory (e.g.
To use it, all you have to do is install it, create an environment, then activate it, and you are ready to install the pip packages.
To share your pip packages across multiple systems, we need to create a
requirements.txt file, which can be easily done with this command:
pip freeze > requirements.txt
pipenv is similar to
virtualenv, it has one extra feature, which is
Pipfile is similat to what we see as
Pipfile contains all the installed packages in the current environment, and automatically updates itself if you install a new package inside the same environment.
Although in my personal opinion,
pipenv is kinda slow compared to
virtualenv but it comes with some extra features.
pipenv aims to combine
virtualenv into one command.
It serves the same purpose as
virtualenv, but only has a subset of its features. As per official docs:
*venvprovides support for creating lightweight virtual environments with their own site directories in isolation.*
In many Linux distributions,
venv comes preinstalled with Python 3, you can verify it using this command:
python3 -m venv -h
All of them are good, go for
virtualenv as it is most easy to use, and efficient tool. Otherwise, you have other choices, spend some more time with each of them, even there are some more like
It's your personal choice, but you give a try to at least few of them.
