Answer 1

Уже решено. Кажется, что моя система использует другую версию php от IIS Express, которая использует старую версию php. Я просто изменяю свою переменную окружения, чтобы указать на мой xampp php, который имеет последнюю версию php

Answer 2

У меня была эта проблема только сейчас, и я исправил ее, изменив переменную окружения Path из операционной системы, чтобы указать на папку php wamp, которая содержит последнюю версию php. Для того, чтобы сделать это (я должен был исследовать это тоже) - Я пошел по этой ссылке и следовали инструкциям: https://www.java.com/en/download/help/path.xml

старая переменная Path выглядит следующим образом: C: \ wamp64 \ Bin \ PHP \ php5.6.25 и я сменил его на C: \ wamp64 \ bin \ php \ php7.0.10 Сэкономил все, все закрыло, перезапустил мой компьютер, а затем без проблем работал. Надеюсь, это сэкономит время для исследования.

Answer 3

Вам нужно сделать одну из двух вещей.

Решение 1 - Вам необходимо обновить версию PHP. Если у вас нет правильной версии, Laravel не будет работать правильно.

Решение 2 - Возможно, у вас есть правильная версия PHP, но композитор по какой-то причине не видит этого. Легко исправить, вам просто нужно использовать команду --ignore-platform-reqs. Это позволит вам устанавливать вещи с композитором независимо от версии PHP.
