## 🔍 Common Issues

### 1. Command Not Found

**Problem:** `i18n` command not found after installation.

**Solutions:**
```bash
# Reinstall globally
npm uninstall -g @logistically/i18n-cli
npm install -g @logistically/i18n-cli

# Check installation
which i18n
i18n --version

# Use npx instead

# Check PATH
echo $PATH
```

### 2. Permission Denied

**Problem:** Permission denied when running commands.

**Solutions:**
```bash
# Fix permissions
sudo npm install -g @logistically/i18n-cli

# Use npx (no global install needed)
