php - 尝试在 ec2 上安装 php-mbstring 的依赖问题

Question

我正在尝试yii2在我的 Amazon Linux AMI 实例上安装，它需要php-mbstring扩展才能工作。

当我尝试运行sudo yum install php-mbstring时，它返回了这个错误：

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

提前感谢您的时间

Answer 1

看来你已经安装了 php 5.6。
您需要mbstring为该特定版本安装php.

跑sudo yum install php56-mbstring

之后，重新启动 apache 可能是个好主意（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
