Question

我在安装laravel5.3框架时遇到了困难，问题是当我用作为composer create-project --prefer-dist laravel/laravel blog的作曲家安装最新版本时，它会自动安装laravel 5.2而不是“laravel 5.3”

当我将laravel 5.2更改为laravel 5.3文件中的composer.json并运行composer update时，会出现这样的错误。

但我有新的安装xampp，显示我的PHP version是7.0.13（通过此回显＆＃39;当前PHP版本检查：＆＃39; .phcversion（）;）发生了什么？为什么我无法安装Laravel 5.3？

Answer 1

我认为最好安装一个新的Laravel 5.3而不是升级它。这是更多的工作，但避免许多问题。

在运行composer create-project --prefer-dist laravel/laravel blog之前，请将您的系统配置与laravel 5.3 require configuration

进行比较

<强>更新
您可以针对特定的laravel版本尝试composer create-project --prefer-dist laravel/laravel=5.3.* blog，然后运行composer update。

Answer 2

首先你应该更新你的php版本（使用7.0）因为laravel 5.3通常适用于php7.0，然后你应该将composer.json中的laravel版本从5.2更改为5.3然后再运行composer update !!!!!! 一切都会好的。

Laravel 5.3未安装
