"""Installiert die Abhängigkeiten aus pyproject.toml in die aktuelle Python-Umgebung.
|
||||||
|
|
||||||
|
Ersatz für "Install requirements" aus PyCharm, wenn das Projekt eine pyproject.toml
|
||||||
|
statt einer requirements.txt hat. Kein Build, keine besondere Projektstruktur nötig,
|
||||||
|
nur Standardbibliothek (Python >= 3.11).
|
||||||
|
|
||||||
|
Benutzung:
|
||||||
|
In PyCharm: Rechtsklick auf diese Datei -> Run 'install_dependencies'
|
||||||
|
Im Terminal (venv aktiv): python install_dependencies.py
|
||||||
|
|
||||||
|
Ohne Parameter wird ALLES installiert:
|
||||||
|
[project].dependencies + alle [project.optional-dependencies] + alle [dependency-groups]
|
||||||
|
|
||||||
|
Abweichendes Verhalten:
|
||||||
|
python install_dependencies.py --extra dev nur Basis + Extra "dev"
|
||||||
|
python install_dependencies.py --group test nur Basis + Gruppe "test"
|
||||||
|
python install_dependencies.py --no-main --group dev
|
||||||
|
python install_dependencies.py --list nur anzeigen, nichts installieren
|
||||||
|
python install_dependencies.py --write requirements.txt schreiben statt installieren
|
||||||
|
python install_dependencies.py --write -o reqs.txt
