![]() ![]() This way you can see which is the active environment. You will notice that the name of the environment is shown on the left of the prompt. This ensures that only packages under my-env/ are used. You can list the available environments with: lsvirtualenv Activate an Environmentīefore you can start using the environment you need to activate it: source my-env/bin/activate For instance, python2.7: virtualenv -python=/usr/bin/python2.7 my-env List Environments Just use the argument -python=/path/to/python/version. You can also specify the Python version you want to work with. This folder contains the directories for installing modules and Python executables. This creates a folder in the current directory with the name of the environment ( my-env/). ![]() To create a virtual environment use: virtualenv -no-site-packages my-env ![]() Verify the installation with the following command: virtualenv -version Create an Environment You can install it with pip: pip install virtualenv It creates a folder which contains all the necessary executables to use the packages that a Python project would need. Virtualenv is a tool used to create isolated Python environments. ![]() Here are two ways you can create Python virtual environments. You can easily release your project with its own dependent modules.This way, different projects’ requirements can be satisfied at the same time. You can have multiple environments, with multiple sets of packages, without conflicts among them.This is where virtual environments come in handy. If you install Pak version 2.3 for App1, you would not be able to run App2 because it requires version 3.1. Both use the package Pak, but require different versions. Imagine you have two applications, App1 and App2. This isolation allows you to localized the installation of your project’s dependencies, without forcing you to install them system-wide. Virtual environments can be described as isolated installation directories. ![]()
