How to associate a virtual environment with a Python project in PyCharm
When it comes to Python development, PyCharm is my favourite IDE.
Before working on a new Python project, I like to create a virtual environment and associate it with the corresponding PyCharm project. In case you like this mode of operation, this is how you can associate a virtual environment with a Python project in PyCharm.
Creating a virtualenv environment for a new Python 3 project
First, let us create a virtual environment for that new Python 3 project.
Since Python 3.5, the recommended way to create a new virtual environment is through the venv module within Python 3.
When we have a version later than Python 3.5 installed on an linux environment, we can run the following command to create a virtual environment:
python3 -m venv proj_1_venv
After the command completes, you will find the proj_1_venv folder in your current working directory. Inside proj_1_venv folder, you will find a bin folder that contains the Python binary and scripts to activate and deactivate the virtual environment.
