尝试在ec2上安装php-mbstring的依赖性问题

Question

我正在尝试在Amazon Linux AMI实例上安装yii2 ，它需要php-mbstring扩展名才能工作。

当我尝试运行sudo yum install php-mbstring它返回以下错误：

错误：php56-common与php-common-5.3.29-1.8.amzn1.x86_64冲突

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

谢谢你的时间

Answer 1

看来您已安装php 5.6。
您需要为特定版本的php安装mbstring 。

运行sudo yum install php56-mbstring

之后，最好重新启动apache（谢谢！ @hexicle ），
使用sudo service httpd restart

Answer 2

Amazon Linux AMI版本2017.09

sudo yum install php70-mysqlnd
sudo service httpd restart
