lxml包引入错误
在使用第三方包lxml引入etree模块时报错:
[python] view plain copy
- >>> from lxml import etree
- Traceback (most recent call last):
- File "<stdin>", line 1, in ?
- ImportError: dynamic module does not define init function (initetree)
由于之前安装是直接使用源码包进行安装,报错之后决定卸载掉源码安装的版本(直接删除site-packages目录下面的lxml包文件),然后重新使用easy_insall命令安装,安装过程中报错信息如下:
[sql] view plain copy
- ERROR: /bin/sh: xslt-config: command not found
- ** make sure the development packages of libxml2 and libxslt are installed **
于是分别安装libxml2 and libxslt模块:
[sql] view plain copy
- 1027 yum install libxml2
- 1028 yum install libxslt
检查xslt-config命令是否安装成功:
[sql] view plain copy
- [root@oser623 mongodb]# whereis xslt-config
- xslt-config:
- [root@oser623 mongodb]#
xslt-config命令还是不存在,在网上找了找资料,提示说需要安装 libxslt-devel
[sql] view plain copy
- 1033 yum install libxslt-devel
现在再来尝试安装 lxml模块
[sql] view plain copy
- [root@oser623 mongodb]# whereis xslt-config
- xslt-config: /usr/bin/xslt-config
- [root@oser623 mongodb]# easy_install lxml

包导入测试:
[sql] view plain copy
- [root@oser623 mongodb]# python
- Python 2.4.3 (#1, Feb 22 2012, 16:05:45)

安装成功!
