Python lxml安装报错， 提示 Could not find function xmlCheckVersion in lib

1、安装lxml时报错$sudopipinstalllxml错误信息如下:Compilefailed:command‘gcc’failedwithexitstatus1/tmp/easy_install-lk8jAw/lxml-3.6.1/temp/xmlXPathInit2tf2ts.c:1:26:错误:libxml/xpath.h:没有那个文件或目录CouldnotfindfunctionxmlCheckVersioninlibrarylibxml2.Islibxml2i
安装lxml时报错
$sudo pip install lxml

错误信息如下:

 

Compile failed: command ‘gcc’ failed with exit status 1
/tmp/easy_install-lk8jAw/lxml-3.6.1/temp/xmlXPathInit2tf2ts.c:1:26: 错误:libxml/xpath.h:没有那个文件或目录

Could not find function xmlCheckVersion in library libxml2. Is libxml2 installed?

error: Setup script exited with error: command ‘gcc’ failed with exit status 1

 

2、安装libxml2
$sudo yum install libxml2

 

3、重新安装lxml
$sudo pip install lxml
还是提示相同的错误信息。

 

4、检查是否安装 libxml2-dev、 libxslt-devel
$sudo yum install libxslt-devel

 

会同时安装依赖 libxml2-devel

 

5、再次安装lxml
$sudo pip install lxml
安装成功。
