Script: Setup Python Virtual Environment and Install Dependencies

This Bash script automates the setup of a Python virtual environment, installation of dependencies, and updating the requirements.txt file. Additionally, it provides an option to install the dependencies globally and configure the script for global access.

Functionality

1. Navigate to Script Directory: Automatically moves to the directory where the script is located.
2. Remove Old Virtual Environment: Deletes any existing Python virtual environment (venv/) to ensure a fresh setup.
3. Create a New Virtual Environment: Initializes a new virtual environment in the current directory.
4. Activate Virtual Environment: Activates the newly created environment.
5. Install Dependencies: Installs required Python packages specified in requirements.txt.
6. Update requirements.txt: After installation, the requirements.txt is updated with the latest installed packages.

Option 1: Install with Virtual Environment (Recommended)

Steps:

1. Clone the repository or download the script.

2. Ensure you have Python 3 installed on your system.

3. Run the script:

   ./pip-env.sh

This will create a virtual environment, install the dependencies, and activate the environment.

Option 2: Install Requirements Globally

If you prefer to install the dependencies globally and make the script available system-wide, follow these steps:

Steps:

1. Install Dependencies Globally:

   Instead of using a virtual environment, you can install the dependencies globally by running:

   pip install -r requirements.txt

2. Add Script to Global PATH:

   Add the bin directory of this repository to your system's PATH to run the script globally from anywhere.

   • Edit your shell configuration file (e.g., ~/.bashrc, ~/.zshrc) and add the following line:

     export PATH="/path/to/your/repo/bin:$PATH"

     Replace /path/to/your/repo/bin with the full path to the bin directory in your repository.

3. Reload your shell:

   After updating the PATH, run:

   source ~/.bashrc   # for Bash users
   source ~/.zshrc    # for Zsh users

Now you can run the script globally by simply typing the script name from any location in your terminal.

Prerequisites

• Python 3: Ensure that Python 3 is installed.
• boto3: Add boto3 to your requirements.txt if not already present.

Notes

• This script assumes that requirements.txt is in the same directory as the script.
• For the virtual environment option, the script regenerates the environment each time it is run, deleting the old one.
• For the global installation option, make sure you have the necessary permissions to install global Python packages.
