因此，我正在CentOS7上工作，并且一直在尝试创建一个包含站点本地Drush install (http://docs.drush.org/en/master/install/)的工作Drupal Composer模板(https://github.com/drupal-composer/drupal-project)。对于我们的项目，我们需要使用PHP5.6和Drupal8.2。

根据上面的说明，我在CentOS的全新virtualbox安装中执行了以下操作：

已安装git。

安装php 5.6：

代码语言：javascript
复制
rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm 
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm 

yum install php56w php56w-opcache

现在我下载composer并全局安装：

代码语言：javascript
复制
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');" 
php -r "if (hash_file('SHA384', 'composer-setup.php') === '669656bab3166a7aff8a7506b8cb2d1c292f042046c5a994c43155c0be6190fa0355160742ab2e1c88d40d5be660b410') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;" 
php composer-setup.php 

mv composer.phar /usr/local/bin/compose

我可以运行composer，它似乎工作得很好。

现在，根据Drupal Composer的说明，我们可以使用composer创建我们的drupal项目，使用：

代码语言：javascript
复制
composer create-project drupal-composer/drupal-project:8.x-dev some-dir --stability dev --no-interaction

项目模板即会生成。

然而，我的问题是我不能运行

代码语言：javascript
复制
composer require drush/drush

或

代码语言：javascript
复制
composer update

因为我得到了这些错误：

To enable extensions, verify that they are enabled in your .ini files:
  - /etc/php.ini
  - /etc/php.d/bz2.ini
  - /etc/php.d/calendar.ini
  - /etc/php.d/ctype.ini
  - /etc/php.d/curl.ini
  - /etc/php.d/exif.ini
  - /etc/php.d/fileinfo.ini
  - /etc/php.d/ftp.ini
  - /etc/php.d/gettext.ini
  - /etc/php.d/gmp.ini
  - /etc/php.d/iconv.ini
  - /etc/php.d/json.ini
  - /etc/php.d/opcache.ini
  - /etc/php.d/phar.ini
  - /etc/php.d/shmop.ini
  - /etc/php.d/simplexml.ini
  - /etc/php.d/sockets.ini
  - /etc/php.d/tokenizer.ini
  - /etc/php.d/xml.ini
  - /etc/php.d/zip.ini
You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

Composer拒绝更新。搜索了几天后，我似乎不知所措了。我不知道我到底需要在这些文件中修改什么，我也没有看到任何人在他们的composer下载中有同样的错误(而且大多数帖子似乎已经过时了几年)。

有没有人能就我在这里遗漏的东西提供一些见解？

谢谢。

编辑:多亏了@Oliver，我发现问题出在我需要php-xml，它是我为php5.6安装的，使用：

代码语言：javascript
复制
sudo yum install php56w-xml

可以在他的评论中的链接中找到扩展。

现在我正在考虑该怎么做，因为我没有看到该站点上列出了drupal/core或easyrdf。我的新错误如下：

代码语言：javascript
复制
  DrupalProject\composer\ScriptHandler::checkComposerVersion
  Loading composer repositories with package information
  Updating dependencies (including require-dev)

To enable extensions, verify that they are enabled in your .ini files:
  - /etc/php.ini
  - /etc/php.d/bz2.ini
  - /etc/php.d/calendar.ini
  - /etc/php.d/ctype.ini
  - /etc/php.d/curl.ini
  - /etc/php.d/dom.ini
  - /etc/php.d/exif.ini
  - /etc/php.d/fileinfo.ini
  - /etc/php.d/ftp.ini
  - /etc/php.d/gettext.ini
  - /etc/php.d/gmp.ini
  - /etc/php.d/iconv.ini
  - /etc/php.d/json.ini
  - /etc/php.d/opcache.ini
  - /etc/php.d/phar.ini
  - /etc/php.d/shmop.ini
  - /etc/php.d/simplexml.ini
  - /etc/php.d/sockets.ini
  - /etc/php.d/tokenizer.ini
  - /etc/php.d/xml.ini
  - /etc/php.d/xml_wddx.ini
  - /etc/php.d/xmlreader.ini
  - /etc/php.d/xmlwriter.ini
  - /etc/php.d/xsl.ini
  - /etc/php.d/zip.ini
You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

当if被计算出来时，将会更新。

最终编辑:确定easyrdf需要ext-mbstring和ext-pcre。ext-pcre安装了通用的php包，所以我所需要的就是ext-mbstring：

代码语言：javascript
复制
sudo yum install php56w-mbstring

现在，当调用composer更新时，我所有的依赖项都被下载了！现在我可以运行vender/bin/drush命令了，确认本地安装已经完成！

dom
drupal
composer-php
drush

这与作曲家无关。您只是缺少了一个php扩展名。我不知道你的php版本是什么，也不知道你的服务器上有什么操作系统。我发布了一些bash的示例：

编辑:现在我找到你的版本了：

CentOS-示例：

代码语言：javascript
复制
sudo yum install php56w-xml
