Python Virtual Environments
There are many packages that relates to python virtual environments. For example,
virtualenv
pyenv
pipenv
- Standard python library
venv
module
All the modules are python packages and can be installed by pip
command. The standard venv
module is shipped with python. So we do not need to install it if we have python.
See What is the difference between venv, pyvenv, pyenv, virtualenv, virtualenvwrapper, pipenv, etc?
Difference
Standard venv
vs virtualenv
.
-
The
venv
module supports creating lightweight “virtual environments”, each with their own independent set of Python packages installed in theirsite
directories. A virtual environment is created on top of an existing Python installation, known as the virtual environment’s “base” Python, and may optionally be isolated from the packages in the base environment, so only those explicitly installed in the virtual environment are available. -
virtualenv
is a tool to create isolated Python environments. Since Python3.3
, a subset of it has been integrated into the standard library under thevenv
module. However, thevenv
module does not offer all features of this library.virtualenv
can be installed bypip
:
$ python -m pip install --user virtualenv
