使用php 7.3.2在xampp中进行magento 2 composer安装问题

Question

I just tried to install Magento 2 on my local server Xampp

I installed the composer and when tried to run composer install in command prompt , I got a error

amzn/amazon-pay-and-login-with-amazon-core-module 3.2.9 requires php 7.1.3- 7.2.0 your php version 7.3.2 doesn't satisfy that requirment.

How can I resolve this issue?

Answer 1

The current version of the amzn/amazon-pay-and-login-with-amazon-core-module package requires PHP version 7.2 . You're on PHP version 7.3.2 which is not supported by version 3.2.9 of the package (yet).

You have multiple options to resolve the issue:

1. Downgrade to PHP 7.2.x to match the package's requirements.

2. Try to install a newer version of the package or directly from the master branch.

   If the compatibility with PHP 7.3 has been added to the package's composer.json ie in a newer version or on the master branch you can use:

    # install the master branch composer require 'amzn/amazon-pay-and-login-with-amazon-core-module:dev-master' # install a version greater than 3.2.9 composer require 'amzn/amazon-pay-and-login-with-amazon-core-module:~3.2.10' 

3. Ignore the PHP version requirement for a single composer install with:

    composer install --ignore-platform-reqs 

4. Override the PHP version in your composer.json .

    "config": { "platform": { "php": "7.2.21" } } 

   This way all subsequent runs of composer install|update will resolve the PHP to version 7.2.21 .
