PHP 작곡가는 php 5.6과 함께 Drush를 설치하지 않습니다 : phpunit/phpunit 4.8.x는 ext-dom을 필요로합니다

Question

그래서 CentOs 7에서 일하고 있으며 작동하는 Drupal Composer 템플릿 (https://github.com/drupal-composer/drupal-project)을 생성하려고 시도했습니다. 사이트 로컬 드릴 설치 (http://docs.drush.org/en/master/install/). 우리 프로젝트에서는 PHP 5.6과 Drupal 8.2를 사용해야합니다.

설치된 자식을 : 나는에 CentOS의 설치 내 깨끗한 버추얼 박스에서 다음을 수행 한 위의 지침에 따라

.

설치된 PHP 5.6 :

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 

가 지금은 작곡가를 다운로드하고 전 세계적으로 설치 :

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 

내가 작곡가를 실행하고 잘 작동하는 것 같다.

이제 드루팔 작곡가의 지침에 따라 우리가 사용하는 작곡가와의 드루팔 프로젝트를 만들 수 있습니다

작곡가 업데이트를 거부 :

하지만, 내 문제는 내가 이러한 오류를 얻을 수 있기 때문에 내가

composer require drush/drush 

또는

composer update 

를 실행할 수 있다는 것입니다. 인터넷 검색의 며칠 후, 나는 손실에있는 것 같습니다. 나는 그 파일들을 정확히 바꿀 필요가 있는지 모르겠다. 나는 작곡가 다운로드에서 같은 오류가있는 사람을 보지 못한다. (그리고 대부분의 게시물들은 수년간 오래된 것으로 보인다.)

내가 누락 된 부분에 대해 통찰력을 제공 할 수있는 사람은 누구입니까?

감사합니다.

편집 :

sudo yum install php56w-xml 

확장 그의 코멘트에있는 링크에서 찾을 수 있습니다 : 나는 문제가 내가 사용 php5.6가 설치 PHP-XML을 필요로했다 발견 @Oliver에게 감사드립니다.

이제 drupal/core 또는 easyrdf가 해당 사이트에 표시되지 않으므로 어떻게해야 할지를 파악하고 있습니다. 내 새로운 오류는 여기에 있습니다 :

최종 편집 : easyrdf에는 ext-mbstring과 ext-pcre가 필요하다는 것을 알았습니다. EXT-PCRE는 내가 필요한 모든 EXT-mbstring했다 공통의 PHP 패키지와 함께 설치되어 제공 :

sudo yum install php56w-mbstring 

이제 작곡가 내 모든 종속성을 다운로드 한 업데이트 호출 할 때!이제 벤더/bin/drush를 실행할 수 있으며 명령이 작동하여 로컬 설치가 완료되었음을 확인합니다!

편집 :

에 CentOS-예 : https://webtatic.com/packages/php56/

: 현재 PHP 5.6 패키지의 목록을 찾을 수 있습니다

sudo yum install php56w-xml 

지금은 버전을 발견했다
