php-xml instala reclamações de dependência php-common mas isso já está instalado (CentOS)

Question

Como faço para forçar o php-xml a ver a dependência já instalada?

sudo yum install php-xml

reclama:

php-common = 5.1.6-34.el5_8

mas executando yum install php-common

php-common-5.1.6-34.el5_8.i386 already installed

 You could try using --skip-broken to work around the problem
 You could try running: package-cleanup --problems

                        rpm -Va --nofiles --nodigest
The program package-cleanup is found in the yum-utils package.

Atualizar

Eu tentei as limpezas sugeridas e executei novamente os comandos. Eu também corri yum install php-common novamente, primeiro como era a dependência então yum install php-common .

Em seguida, tentei executar novamente os comandos, primeiro yum install php-xml - falhou, talvez a dependência primeiro então? então, yum install php-common - já instalado como vimos antes, então novamente yum install php-xml - ainda falhou: -

Atualização 3

Parece que a versão que tenho de php-common-5.2.10-1.el5.centos é mais recente do que a que está sendo solicitada como uma dependência de php-xml , php-common = 5.1.6-34.el5_8

[root@dtsrvishvt2 /]# rpm -qa |grep php
php-ldap-5.2.10-1.el5.centos
php-common-5.2.10-1.el5.centos
php-5.2.10-1.el5.centos
php-mcrypt-5.2.9-2.el5.centos.3
php-pdo-5.2.10-1.el5.centos
php-cli-5.2.10-1.el5.centos
php-mysql-5.2.10-1.el5.centos
[root@dtsrvishvt2 /]#

Então, como eu forçaria o php-xml a usar a versão posterior que eu já tenho?

(Gerou esta pergunta e perguntou separadamente aqui: Como forçar o CentOS yum a usar uma versão mais recente de uma dependência de pacote já instalada (php-common como uma dependência do php-xml) )

    

Answer 1

A solução é a resposta aceita em:

Como forçar o CentOS yum a usar uma versão mais recente de uma dependência de pacote já instalada (php-common como uma dependência do php-xml)

Em resumo: mova para o php5.3.

Razão: o suporte para o php5.2 foi removido devido a questões de segurança, conforme explicado na resposta aceita pela outra pergunta. Essa remoção causa incompatibilidade das versões das dependências e, portanto, o erro visto.

Plano de fundo

Eu queria rodar o Drupal 7 em uma máquina CentOS 5.4. Então, eu precisava da versão 5.3 do PHP.

Aqui estão as etapas de trabalho completas para atualizar para o PHP 5.3 com repositórios de trabalho em 24 de maio de 2012 (eu forneço comentários precedidos por # - você não precisa deles, apenas para suas informações)

# Comment: sites like http://www.computingunplugged.com/issues/issue201102/00002619001
# provide a good start for remedying the problem whereby we need 5.3 on CentOS 5.4 to run Drupal 7. But although their packages worked at the time, the links are now outdated, and updates to these are below.


# comment: (as of May 2012 - the following work, the reason for failures was use of 1) older packages no longer on the server and 2) change of address of one of the servers to dl.fedoraproject.org/pub/epel (credit to: http://osdir.com/ml/centos/2012-03/msg00057.html )

rpm -Uhv http://apt.sw.be/redhat/el5/en/i386/rpmforge/RPMS/rpmforge-release-0.3.6-1.el5.rf.i386.rpm
rpm -Uvh http://dl.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm
rpm -Uvh http://dl.iuscommunity.org/pub/ius/stable/Redhat/5/i386/ius-release-1.0-10.ius.el5.noarch.rpm  

yum erase php php-pear php-mysql php-cli php-common  

yum install php53u php53u-pear php53u-cli php53u-common php53u-gd  
yum install php53u-mbstring php53u-mcrypt php53u-mysql php53u-soap  
yum install php53u-xml php53u-xmlrpc php53u-bcmath 


# After doing the above, php -v shows 5.3.x But on attempting to install Drupal 7 you may get complaint of something "Your PHP installation is too old 5.1.6 Drupal requires at least PHP 5.2.4. See the system requirements page for more information." and php.info shows the same

# The remedy is to simply restart your apache server

service httpd restart

# credit to following for suggesting service httpd restart :-
# https://serverfault.com/a/207806/29205
# https://serverfault.com/questions/207762/centos-updating-php-via-yum-doesnt-change-the-version-apache-uses

# Drupal 7 install on CentOS 5.4 worked after applying the above steps

# If your MySQL server is not running (check by ps -ef | grep mysql ) then you can run:

/etc/init.d/mysqld

# ...to start it, and to make sure it starts when the machine is restarted or cold booted:

chkconfig mysqld on

    

Answer 2

Você tentou os comandos que yum pediu para você executar para corrigir a situação?

package-cleanup --problems
package-cleanup --dupes
rpm -Va --nofiles --nodigest

Experimente e depois veja se você pode instalar php-xml .

EDIT: Apenas por diversão, execute yum clean all e depois tente reinstalar php-xml .
