How Can I Use Virtualenv to Specify a Particular Python Version?

Using Virtualenv to Specify Python Versions

Virtualenv is a tool that allows you to isolate Python environments and their dependencies, enabling developers to work with different versions of Python concurrently. To create a virtual environment for a specific Python version, follow these steps:

Use the --python (or short -p) option when creating a virtualenv instance. This option specifies the Python executable you want to use. For example:

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

In this command, we specify the Python 2.6 executable located at /usr/bin/python2.6 and create a virtual environment in the directory /path/to/new/virtualenv/.

Note for Python 3.3 Users:

For Python versions 3.3 and above, the syntax has changed. Instead of --python, use the -p option. The command becomes:

virtualenv -p /usr/bin/python3.6 "/path/to/new/virtualenv/"
