本文操作环境：ubuntu 16.04系统、PHP7.0版、DELL G3电脑
ubuntu服务器下php7没有phpize文件解决方案
第一种：
sudo vim /etc/resolv.conf
添加nameserver 8.8.8.8
第二种：
/etc/apt/sources.list 的内容换成 deb http://old-releases.ubuntu.com/ubuntu/ raring main universe restricted multiverse deb-src http://old-releases.ubuntu.com/ubuntu/ raring main universe restricted multiverse deb http://old-releases.ubuntu.com/ubuntu/ raring-security main universe restricted multiverse deb-src http://old-releases.ubuntu.com/ubuntu/ raring-security main universe restricted multiverse deb http://old-releases.ubuntu.com/ubuntu/ raring-updates main universe restricted multiverse deb-src http://old-releases.ubuntu.com/ubuntu/ raring-updates main universe restricted multiverse deb http://old-releases.ubuntu.com/ubuntu/ raring-backports main restricted universe multiverse deb-src http://old-releases.ubuntu.com/ubuntu/ raring-backports main restricted universe multiverse deb http://old-releases.ubuntu.com/ubuntu/ raring-proposed main restricted universe multiverse deb-src http://old-releases.ubuntu.com/ubuntu/ raring-proposed main restricted universe multiverse
然后sudo apt-get update一下
再执行 apt-get install php7.0-dev
知识点扩展：
没有PHPIZE的解决方法
# which phpize
/usr/bin/phpize# rpm -q –whatprovides /usr/bin/phpize
php-devel-4.3.10-3.2Give “yum install php-devel” a try!
在redhat的网站上找到了这个
默认centOS和FC6都没有装这个phpize
就像上面说的，yum install php-devel
