Sure, changing the Python version of a virtual environment can be necessary when working on different projects with specific Python version requirements. Here's a step-by-step tutorial on how to change the Python version in a virtual environment using virtualenv and venv.
If you don't have virtualenv installed, you can install it using pip:
Create a virtual environment using virtualenv with the desired Python version. Replace desired_python_version with the Python version you want, such as 3.8, 3.9, etc.:
Replace /usr/bin/pythondesired_python_version with the path to the Python interpreter of the desired version. For example, for Python 3.8, it could be /usr/bin/python3.8.
To activate the newly created virtual environment:
You can verify that the correct Python version is active by using:
venv is a module available in Python 3 for creating virtual environments.
Navigate to the directory where you want to create the virtual environment and run:
Replace pythondesired_python_version with the version of Python you want to use. For instance, python3.8 -m venv myenv.
Activation process is the same as with virtualenv.
Verify the Python version in the same manner as before:
To deactivate the virtual environment and return to the global Python environment, simply type:
Remember to replace desired_python_version with the actual version number you want to use. This allows you to switch between Python versions easily within separate virtual environments, ensuring compatibility for different projects.
