我试图安装一个全新的Wheezy安装php5-mysqlnd（/ etc / debian_version指wheezy / sid），我遇到了一个问题：
root@debian:/var/www/lottery1# apt-get install php5-mysqlnd Reading package lists... Done Building dependency tree Reading state information... Done php5-mysqlnd is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. 1 not fully installed or removed.

有什么想法吗？ 我试图运行一个networking工具，大量使用mysqli_result :: fetch_all（）。
谢谢！
所以删除php5-mysql后，我不得不强制删除php5-mysqlnd，然后我必须清除php5-mysql，然后我必须清除php5-mysqlnd，然后我可以安装php5-mysqlnd。
dpkg --remove --force-remove-reinstreq php5-mysqlnd dpkg --purge php5-mysql dpkg --purge php5-mysqlnd
只有一次dpkg -l | grep php5-mysql dpkg -l | grep php5-mysql没有输出，我可以apt-get install php5-mysqlnd并让它工作。
