Offline Python Package Installer & Virtual Environment Manager

This tool is a comprehensive offline package downloader and installer for Python projects. It allows you to:

• Download packages offline: Save package files into a designated folder (libay).

• Install packages offline: Install packages from the offline folder without requiring an Internet connection.

• Create a virtual environment: Set up a Python virtual environment (venv) and install packages into it.

• Run a Python script within the virtual environment: Opens a new terminal window (PowerShell on Windows or gnome-terminal on Linux) and runs your script.

• Select a desired Python version: Choose from 3.9, 3.10, 3.11, 3.12, or 3.13 to determine which package versions to install.

• Platform-specific handling: On Windows, the uvloop package is automatically skipped as it is intended only for Linux.

Features

• Offline Download & Installation: Operate without a constant network connection.

• Python Version Selection: Set the desired Python version for package recommendations.

• Virtual Environment Management: Create and populate a development environment with your specified packages.

• Cross-Platform: Automatically detects Windows vs. Linux and adjusts the execution method.

Requirements

• Python 3.9 or newer (the tool supports library versions for Python 3.9, 3.10, 3.11, 3.12, and 3.13).

• Pip (usually included with Python).

• On Windows: PowerShell is required for running applications in the virtual environment.

• On Linux: A terminal emulator such as gnome-terminal is assumed for launching the script in a new window.

Usage

1. Download the Script Files:

   • Save installer.py and packages.py to your working directory.

   • Refer to this README.md for usage instructions.

2. Run the Installer:

   Python installer.py
   

3. Select Options from the Menu:

   • Option 0: Download packages offline into the libay folder.

   • Option 1: List the files downloaded in libay.

   • Option 2: Install the downloaded packages offline.

   • Option 3: Create a virtual environment (venv) and install packages into it.

   • Option 4: Run a Python script within the virtual environment (opens a new terminal window).

   • Option 5: Set your desired Python version (choose between 3.9, 3.10, 3.11, 3.12, or 3.13).

   • Option q: Quit the application.

4. Follow the Prompts:

   • The tool displays informative messages as it processes your selections.

   • When setting the Python version or providing a file path, follow the on-screen instructions.

Notes

• uvloop Package: This package is intended only for Linux. In Windows environments, it will be skipped automatically.

• Terminal Emulation on Linux: This script currently uses gnome-terminal to launch a new terminal window. Adjust the run_app_in_venv() function if you use a different terminal emulator.
