php - 我是 ubuntu 的新手。我已经安装了 phpstorm 并尝试运行 composer 但它没有运行

Question

我已经在 ubuntu 14.04 上安装了 phpstorm当我尝试使用命令 php artisan migrate 访问数据库时出错:

 wwwsabininfonp@wwwsabininfonp-Aspire-E1-471:/opt/lampp/htdocs/fine-arts$ php artisan migrate                                                                                                             
  [PDOException]                                                                                               
  SQLSTATE[HY000] [2002] Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)  

当我尝试使用命令 composer update 时发生以下错误:

    Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - gregwar/captcha dev-master requires ext-gd * -> the requested PHP extension gd is missing from your system.
    - gregwar/captcha dev-master requires ext-gd * -> the requested PHP extension gd is missing from your system.
    - Installation request for gregwar/captcha dev-master -> satisfiable by gregwar/captcha[dev-master].

不知道为什么这段代码在骂我.....

错误表明您需要 PHP 的“gd”扩展。您应该能够像这样安装它:

sudo apt-get install php5-gd
