无法在GoDaddy主机执行composer命令，求助AddChat-Laravel-Pro安装问题

Hey there, let's break down how to tackle your installation problems step by step:

• First, verify server environment compatibility
  AddChat Laravel Pro relies on specific PHP versions and extensions (core Laravel requirements like BCMath, Ctype, JSON, Mbstring, OpenSSL, PDO, Tokenizer, XML are non-negotiable). GoDaddy's shared hosting often defaults to older PHP versions that might not match what the package needs. Head into your GoDaddy cPanel, check your current PHP version, and switch to the one specified in the AddChat docs (usually PHP 7.3+ for Laravel 8-based builds). Also, double-check that required PHP extensions are enabled—you can toggle these on/off in the PHP Options section of cPanel.

• Dig into the exact error messages from your terminal commands
  You mentioned command execution failed, but without the specific error output, it's hard to pinpoint the issue. Was it a composer install failure due to missing dependencies? A php artisan migrate error from bad database credentials? Or a permission block? Copy the full error text from your Putty session—this will tell us whether it's a memory limit, permission, or configuration problem.

• Address the free -m anomaly
  GoDaddy's shared hosting often restricts access to system-level memory stats, or shows limited allocated memory instead of the full server memory. If memory shortages are causing your install commands to crash, try these workarounds:

  • Bump Composer's memory limit temporarily:

    php -d memory_limit=-1 composer install
    

  • Adjust Node.js memory for npm commands if you're running frontend builds:

    NODE_OPTIONS="--max-old-space-size=2048" npm install
    

  • If you're on a shared plan and still hit limits, reach out to GoDaddy support to check if you can upgrade your memory quota or if there are hosting-specific restrictions blocking the install.

• Fix file permissions (a common GoDaddy pitfall)
  GoDaddy enforces strict file permissions, and Laravel needs write access to the storage and bootstrap/cache directories. Run these commands in Putty (replace your-cpanel-username with your actual cPanel username):

  chmod -R 755 storage bootstrap/cache
  chown -R your-cpanel-username:your-cpanel-username storage bootstrap/cache
  

  Skipping this step will almost certainly lead to errors during installation or runtime.

• Double-check your .env configuration
  Make sure you've filled in the .env file correctly, especially the database settings. GoDaddy doesn't use localhost as the database host—you'll need to grab the specific database hostname from your cPanel's Database Manager. Also, confirm the APP_URL matches your domain exactly, including http/https if applicable.
