| + | # Python Virtual Environment |
| + | |
| + | ## Overview |
| + | | Action | Command | |
| + | | - | - | |
| + | | <a href="#install-required-packages">Install</a> | `sudo apt install python3-venv` | |
| + | | <a href="#create">Create</a> | `python3 -m venv .venv` | |
| + | | <a href="#activate">Activate</a> | `source .venv/bin/activate` | |
| + | | <a href="#deactivate">Deactivate</a> | `deativate` | |
| + | |
| + | ## Install Required Packages |
| + | ```bash |
| + | sudo apt install python3-venv |
| + | ``` |
| + | - installiert das python modul venv zum erstellen von virtual environments |
| + | |
| + | ## Create |
| + | ```bash |
| + | python3 -m venv .venv |
| + | ``` |
| + | - executes python3 of PATH (? default python3 of the system) |
| + | - executes modul venv (for virtual environment) |
| + | - creates new directory .venv |
| + | - initializes virtual python environment in .venv/ |
| + | - creates the following structure: |
| + | ``` |
| + | /home/<user>/<project>/ |
| + | |---.venv/ |
| + | | |--- bin/ |
| + | | |--- lib/ |
| + | | |--- ... |
| + | |--- <myprogram.py> |
| + | ``` |
| + | |
| + | ## Activate |
| + | ```bash |
| + | source .venv/bin/activate |
| + | ``` |
| + | - activates the python virtual environment within .venv/ |
| + | - all following python executions are made from within this virtual environment |
| + | - console inserts virtual environment name at beginning: |
| + | ```bash |
| + | (venv) <user>@raspberrypi:~/<project> $ |
| + | ``` |
| + | ### Alternative |
| + | - alternatively the python virtual environment can directly be called (e.g. from scripts): |
| + | ```bash |
| + | /home/<user>/<project>/.venv/bin/python ... |
| + | ``` |
| + | |
| + | |
| + | ## Deactivate |
| + | ```bash |
| + | deactivate |
| + | ``` |
| + | - deactivates the active virtual environment |
