При установке Composer произошел конфликт версий php

Answer 1

Ваша версия php не поддерживается laravel.У вас есть php 7.0.25, но для laravel требуется минимальный php 7.1.3.

Решение: обновите свой php до 7.1.3

Требования к серверу для последней версии laravel:

PHP >= 7.1.3
OpenSSL PHP Extension
PDO PHP Extension
Mbstring PHP Extension
Tokenizer PHP Extension
XML PHP Extension
Ctype PHP Extension
JSON PHP Extension
BCMath PHP Extension

Вы можете обновить свою версию php с помощью следующих команд:

1. Добавить репозиторий ondrej / php:

sudo add-apt-repository ppa: ondrej / php

Обновите ваши списки пакетов:

sudo apt-get update

Установить php 7.3:

sudo apt установить php7.3 php7.3-common php7.3-cli

Установите несколько расширений php 7.3:

apt install php7.3-bcmath php7.3-bz2 php7.3-curl php7.3-gd php7.3-intl php7.3-json php7.3-mbstring php7.3-readline php7.3-xml php7.3-zip

Отключить php 7.0:

sudo a2dismod php7.0

Включить php 7.3:

sudo a2enmod php7.3

Полное удаление php 7.0 из вашей системы:

apt purge php7.0 php7.0-common php7.0-cli

Answer 2

Вам необходимо обновить версию php. Используйте следующую строку для обновления php

sudo apt-add-repository ppa:ondrej/php

sudo a2dismod php7.0        //Disable php 7.0
sudo a2enmod php7.1         //Enable php version 7.1
