composer 卸载和安装

如果是virtualbox安装的 就 进入虚拟机 把  /home/vagrant/.config  下面的 composer 删除掉
重新安装 composer.phar   分别复制的  /bin/composer  和  /usr/local/bin/composer

共享目录安装composer报错提示如下

安装的时候一定  不要在共享目录安装比如  /var/www/html
建议在根目录创建一个  myself ,项目移动到这个下面, 执行 composer

[vagrant@localhost html]$ composer create-project hyperf/hyperf-skeleton
Creating a "hyperf/hyperf-skeleton" project at "./hyperf-skeleton"

[vagrant@localhost html]$ pwd

其他目录安装,可以正常安装
