Laravel框架Warning: require(../vendor/autoload.php): failed to open stream: No such file or directory
Laravel框架Warning: require(../vendor/autoload.php): failed to open stream: No such file or directory
最近在学习Laravel框架，在phpstudy下使用composer+laravel安装器的方式安装了Laravel，但是访问的时候报错：
Warning: require(D:\phpstudy\WWW\public\myblog\bootstrap/../vendor/autoload.php): failed to open stream: No such file or directory in .../autoload.php on line 17
通过百度了解到在项目根目录运行composer update命令可以解决这个问题。
但是我在运行composer update时报错
很明显，错误表示最新版本的Laravel5.6版本需要php7.1.3以上版本，但是我的php是7.0.12。
而通过Laravel安装器安装Laravel框架时无法指定具体版本，
最终解决办法就是删掉项目文件，通过Composer Create-Project命令指定版本安装Laravel。
composer create-project --prefer-dist laravel/laravel myblog 5.5.*
=========================================================
注意：一定要注意laravel的版本对应什么版本的php
下面是cmd运行实例：composer创建项目实例
