Ubuntu 16.04默认安装php7.0环境,但是php7目前兼容性并不是很好,如果自行安装php5需要清除php7的已安装包,否则会报错。 移除默认及已安装的PHP包 sudo dpkg -l | grep php| awk '{print $2}' |tr "\n" " " sudo apt-get install aptitude sudo aptitude purge `dpkg -l | grep php| awk '{print $2}' |tr "\n" " "` 添加 PPA sudo add-apt-repository ppa:ondrej/php
add-apt-repository: command not found
sudo apt-get install software-properties-common python-software-properties
