# # Let me know if it works...

# Step 1: Check React Version
# React v19 does not exist. The latest stable version is React 18.
# Use the correct version:
npx create-react-app@latest my-app

# Step 2: Use --use-npm Option
# If you're using npx, enforce the use of npm:
npx create-react-app my-app --use-npm

# Step 3: Clear Cache
# Clean npm cache to avoid dependency issues:
npm cache clean --force

# Step 4: Use --force or --legacy-peer-deps
# Bypass peer dependency conflicts during installation:
npm install --legacy-peer-deps

# Step 5: Check Dependency Conflicts
# Update dependencies individually if conflicts persist:
npm install react@18 react-dom@18
npm install @testing-library/react@latest

# Step 6: Try Yarn
# If npm fails, switch to Yarn for handling dependencies:
npm install --global yarn
yarn create react-app my-app

# Step 7: Reinitialize the Project
# If all else fails, delete the project and start fresh:
rm -rf my-app
npx create-react-app my-app

# After completing these steps, verify installed versions:
npm list react react-dom
