pypm-manager 2.0.1

Python package manager with centralized storage and zero duplication - works like venv + pip

PyPM - Python Package Manager

Zero-duplication package management for Python - Works like venv + pip but stores packages centrally!

🚀 Quick Start

# Install PyPM
pip install pypm-manager

# Create environment  
pypm create myproject

# Activate it (opens new shell)
pypm activate myproject

# Use pip normally - packages stored centrally!
pip install pandas numpy scikit-learn

# Deactivate when done
deactivate

✨ The Problem PyPM Solves

Before PyPM:

project1/venv/ → pandas 1.5.0 (100 MB)
project2/venv/ → pandas 1.5.0 (100 MB)  [DUPLICATE!]
project3/venv/ → pandas 1.5.0 (100 MB)  [DUPLICATE!]
Total: 300 MB wasted

With PyPM:

~/.pypm_central/ → pandas 1.5.0 (100 MB)  [STORED ONCE!]
All projects reference the same files
Total: 100 MB  (66% savings!)

🎯 How It Works

1. Create: pypm create myenv - Creates environment
2. Activate: pypm activate myenv - Opens activated shell
3. Install: pip install pandas - Packages go to central store
4. Use Anywhere: Activate same environment from any directory!

📦 Installation

pip install pypm-manager

🔧 Commands

# Environment Management
pypm create <name>         # Create environment
pypm activate <name>       # Activate (opens new shell)
deactivate                 # Deactivate current environment
pypm delete <name>         # Delete environment
pypm list                  # List all environments
pypm info <name>           # Show environment details

# Central Store
pypm store-info            # View central store stats
pypm store-install <pkg>   # Install to central store
pypm store-uninstall <pkg> # Remove from central store

💡 Complete Example

# Create data science environment
pypm create datascience
pypm activate datascience

# In activated shell - use pip normally:
pip install pandas numpy matplotlib seaborn scikit-learn jupyter

# Work on your project...
python my_analysis.py

# Deactivate
deactivate

# Later, from anywhere:
pypm activate datascience  # Same environment!
