php7 没有phpize怎么办？
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

/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
