Problema di produzione di Laravel - Aggiornamento del compositore con Laravel 4.1.x

Question

Non ho riscontrato alcun problema nella distribuzione del mio progetto laravel fino ad ora. Sto implementando già da quasi un anno per questo progetto. Ma qualche nuovo bug è venuto fuori.

Prima di tutto. Non riesco ad eseguire l'aggiornamento di compositore, perché dice questo errore.

composer update 
Warning: This development build of composer is over 30 days old. It is recommended to update it by running "/usr/local/bin/composer self-update" to get the latest version. 
Loading composer repositories with package information 
Updating dependencies (including require-dev) 



    [RuntimeException] 
    Could not load package classpreloader/classpreloader in http://packagist.org: [UnexpectedValueException] Could not parse version constraint ^1.2.2: Invalid 
    version string "^1.2.2" 






    [UnexpectedValueException] 
    Could not parse version constraint ^1.2.2: Invalid version string "^1.2.2"

Quindi quello che ho fatto è aggiornare la mia libreria di Composer.

Questa è la mia versione corrente.

Composer version 1e27ff5e22df81e3cd0cd36e5fdd4a3c5a031f4a 2014-08-11 15:46:48 

Ho aggiornato il compositore.

[api@my staging-hoho-middleware]$ sudo composer self-update^C 
[api@my staging-hoho-middleware]$ sudo /usr/local/bin/composer self-update 
Updating to version b2173d28fc8b56236eddc8aa10dcda61471633ec.

[api@my staging-hoho-middleware]$ composer update

Ma ho incontrato un nuovo problema, una volta mi sono imbattuto aggiornamento compositore

[api@my staging-hoho-middleware]$ composer update

Ora sto appoggiato verso disinstallare il mio compositore, e la creazione di una nuova copia fresca.

Answer 1

L'ho risolto installando le dipendenze mancanti.

1008 php -v 
1009 yum search php55 
1010 yum -y install php55w-xml.x86_64 
1011 clear 
1012 su - api 
1013 httpd restart 
1014 service httpd restart 

Answer 2

sudo apt-get install php5.6-xml 

risolto questo per me su Ubuntu con PHP 5.6. (Il suo nulla a che fare con laravel BTW -. Non sto usando tale contesto affatto)

Answer 3

avuto lo stesso problema, eseguite il comando di installazione compositore terminale e problema risolto

il compositore tramite yum comando install :

yum install composer -y 

Answer 4

È possibile installare PHPUnit, dopo di che, se ci sono problemi, eseguire il comando: sudo a2dismod php5 .Se avete ancora domande, per analizzare il problema, cercando nel registro di sistema.
