Setup Environment React Native by ONE Script

FlowChart

This script automates the installation and setup of the essential development environment on macOS, including:

• Homebrew
• RVM (Ruby Version Manager) and Ruby
• NVM (Node Version Manager) and Node.js
• Bundler and Cocoapods
• Yarn
• Xcode Command Line Tools

Prerequisites

Make sure you have the following:

• A macOS system with internet access
• Terminal access

Installation

1. Make the script executable:

   chmod +x setup_env_react_native.sh

2. Run the script:

   ./setup_env_react_native.sh

3. Follow the on-screen instructions: The script will prompt you to enter the Ruby and Node.js versions you want to install. Press Enter to use the default versions.

Post Installation

Once the script completes, you can verify installations with:

ruby -v    # Check Ruby version
node -v    # Check Node.js version
yarn -v    # Check Yarn version
pod --version  # Check Cocoapods version

If you run into any issues, restart your terminal or run:

source ~/.zshrc

Troubleshooting

• If Homebrew is not found, try running:

  /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

• If RVM is not detected, restart your terminal and try:

  source /opt/homebrew/share/rvm/scripts/rvm

• If NVM does not load properly, run:

  source ~/.zshrc

Uninstallation

To remove installed tools, use the following:

brew uninstall rvm nvm
rvm implode
nvm uninstall <node_version>
gem uninstall cocoapods bundler
