How Can I Use Virtualenv to Create Python Environments with Specific Versions?

Leveraging Virtualenv to Specify Python Versions

In Python development, the ability to isolate different projects and their dependencies is crucial. Virtualenv, a powerful tool, facilitates the creation of virtual environments, fostering such isolation.

Creating Virtual Environments for Specific Python Versions

Virtualenv allows you to create virtual environments tailored to specific Python versions, ensuring your projects leverage the appropriate Python environment. To achieve this, employ the --python (--p) option when creating the virtual environment instance. For example, suppose you wish to establish a virtual environment tailored to Python 2.6:

virtualenv --python="/usr/bin/python2.6" "/path/to/new/virtualenv/"

By specifying the path to your desired Python executable, you can effortlessly establish a virtual environment that accords with the targeted Python version.
