Create A Virtual Environment

Category: Python

Tools like virtualenv and virtualenvwrapper provide isolated Python environments which are cleaner than installing packages system-wide. Virtual environments prevent dependency conflicts and also let you install packages without root privileges.

Create a new virtual environment by choosing a Python interpreter and making a ./venv directory for it:

python3 -m venv ./venv

Activate the virtual environment:

source ./venv/bin/activate

Ensure pip is up to date:

pip3 install -U pip

You can then start installing packages using pip3 install <package-name>.
