php - libxml2 configure: error: xml2-config not found. Please check your libxml2 installation.

Question

在Linux下，编译安装PHP时报错：

libxml2 configure: error: xml2-config not found. Please check your libxml2 installation.

但是在Linux下已经安装了libxml2，我通过rpm -qa | grep libxml2就可以查到，那为什么还会提示那个错误呢？

Answer 1

应该是libxml2-dev

ubuntu/debian:

apt-get install libxml2-dev

centos/redhat:

yum install libxml2-devel

Answer 2

安装了 libxml2-devel 之类的没？
