安装 composer，报错 Failed to decode zlib stream错误

1、下载Composer

curl -sS https://getcomposer.org/installer | php

2.设置环境变量

mv composer.phar /usr/local/bin/composer

3.修改权限,否则执行的时候会报错

chmod -R 777 /usr/local/bin/composer

4.composer -v  查询是否安装成功

 

如果安装过程中出现Failed to decode zlib stream错误信息

执行以下命令

yum install epel-release

rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

yum update
