How to use

Using Pip

Inside your project folder, create a virtual environment with the following command:

$ python3 -m venv venv

Then, activate the environment:

$ source venv/bin/activate # for mac users
$ venv\Scripts\activate.bat # for windows users

Using Poetry

$ poetry init

This will create a new pyproject.toml file inside your project root.

Run:

$ poetry add DEPENDENCY_NAME

This will activate your virtual environment if exists or create a new one if it doesn’t.

To install a development package you can use the --dev or -D flags.

The next time you start the project, you can run poetry shell to activate your project virtual env. To deactivate the environment run deactivate.

In VScode, remember to activate the python interpreter as follows:

• Open the command palette with cmd + shift + p or ctrl + shift + p and select > Python: Select Interpreter. Inside, select Enter interpreter path.
• To get your poetry virtual env path in your terminal type:

$ poetry env info -p

• Copy the complete path and paste it in the command palette.
