pip's Introduction

Enviroment

INSTALAR entorno virtual (slo se instala una vez por ordenador los entornos virtuales se fijan con otro comando)

sudo apt installl -y python3-venv

FIJAR nuestro entorno virtual en la carpeta del proyecto:

python3 -m venv env

ACTIVAR entorno virtual

source env/bin/activate

DESACTIVAR entorno virtual:

deactivate

Revisar desde donde se ejecuta Python:

which python3

Revisar desde donde se ejecuta pip:

which pip3

INSTALAR dependencias con el entorno virtual activado:

pip3 install matplotlib

REVISAR dependencias instaladas:

pip3 freeze

INSTALAR dependencia espesifica por version:

python -m venv env

ARCHIVO requirements.txt para instalación de dependencias:

❯ pip3 freeze > requiremments.txt

❯ ls
charts.py  env  main.py  __pycache__  requiremments.txt

❯ cat requiremments.txt
contourpy==1.0.5
cycler==0.11.0
fonttools==4.38.0
kiwisolver==1.4.4
matplotlib==3.6.1
numpy==1.23.4
packaging==21.3
Pillow==9.2.0
pyparsing==3.0.9
python-dateutil==2.8.2
six==1.16.0

INSTALAR dependencias desde archivo requirements.txt

pip3 install -r requirements.txt

Game Project

Para correr el juego debes seguir las siguientes instrucciones en la terminal:

terminal:

cd game
python3 main.py

App Project

> git clone

> cd app

>* python3 -m venv env

> source env/bin/activate

> pip3 install - requirements.txt

> python3 main.py
