在安装PHPHub5 composer install 报错

如果大家谁有完整的安装包可不可以给提供一份！！！ 想学习下里面的内容

在安装PHPHub5的时候， composer install 首先报错

Deprecation warning: require.VentureCraft/revisionable is invalid, it should not contain uppercase characters. Please use venturecraft/revisionable instead. Make sure you fix this as Composer 2.0 will error.

接下来安装依赖库的时候 就是下面图片的样子
