要启用扩展，请验证它们是否在那些.ini文件中启用- Ubuntu

在Ubuntu服务器14.0.4中ssh安装baibaratsky/php-webmoney包时出现错误，代码如下:

composer require baibaratsky/php-webmoney
root@euv:/var/www/my# composer require baibaratsky/php-webmoney
Key kartik-v/yii2-widget-fileinput is a duplicate in ./composer.json at line 25

  To enable extensions, verify that they are enabled in those .ini files:
    - /etc/php5/cli/php.ini
    - /etc/php5/cli/conf.d/05-opcache.ini
    - /etc/php5/cli/conf.d/10-pdo.ini
    - /etc/php5/cli/conf.d/20-gd.ini
    - /etc/php5/cli/conf.d/20-intl.ini
    - /etc/php5/cli/conf.d/20-json.ini
    - /etc/php5/cli/conf.d/20-mysql.ini
    - /etc/php5/cli/conf.d/20-mysqli.ini
    - /etc/php5/cli/conf.d/20-pdo_mysql.ini
    - /etc/php5/cli/conf.d/20-readline.ini
    - /etc/php5/cli/conf.d/20-xsl.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.
Installation failed, reverting ./composer.json to its original content.

我安装了这个包但是没有修复错误。

sudo apt-get install php5-gd
sudo apt-get install php5-intl
sudo apt-get install php5-xsl
