PHP7: Installieren Sie das Ext-Dom-Problem

Ich starte laravel 5.4 auf einem Ubuntu 16.04 Server mit PHP7. Beim Versuch, das cviebrock/eloquent-sluggable -Paket zu installieren, ist ein Fehler aufgetreten:

[email protected]:/home/sherk/ftp/www$ Sudo composer require cviebrock/eloquent-sluggable
Do not run Composer as root/super user! See https://getcomposer.org/root for details
Using version ^4.2 for cviebrock/eloquent-sluggable
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - phpunit/php-code-coverage 4.0.7 requires ext-dom * -> the requested PHP extension dom is missing from your system.
    - phpunit/php-code-coverage 4.0.7 requires ext-dom * -> the requested PHP extension dom is missing from your system.
    - Installation request for phpunit/php-code-coverage (installed at 4.0.7) -> satisfiable by phpunit/php-code-coverage[4.0.7].

  To enable extensions, verify that they are enabled in those .ini files:
    - /etc/php/7.0/cli/php.ini
    - /etc/php/7.0/cli/conf.d/10-mysqlnd.ini
    - /etc/php/7.0/cli/conf.d/10-opcache.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.

Ich habe kein Problem damit, dieses Paket in der lokalen Version der App zu installieren.

Lesen Sie zuerst die Warnung! Es heißt do not composer als root ausführen! Zweitens verwenden Sie wahrscheinlich Xammp auf Ihrem lokalen System, das standardmäßig die erforderlichen PHP-Bibliotheken enthält.

Aber auf deinem Server fehlt dir ext-dom. php7.1-xml enthält alle zugehörigen Pakete, die Sie benötigen. Sie können es also einfach installieren, indem Sie Folgendes ausführen:

Sudo apt-get update
Sudo apt-get install php7.1-xml

Höchstwahrscheinlich fehlt Ihnen auch mbstring. Wenn Sie die Fehlermeldung erhalten, installieren Sie dieses Paket ebenfalls mit:

Sudo apt-get install php-mbstring

Dann renne:

composer update
composer require cviebrock/eloquent-sluggable

Für diejenigen, die ext-dom unter PHP 7.1 und höher installieren möchten, führen Sie den folgenden Befehl aus:

Sudo apt install php-xml

Für CentOS, RHEL, Fedora:

$ yum search php-xml

Wählen Sie dann die php-xml Version, die Ihrer PHP-Version entspricht:
