1、问题
在CentOS下使用yum安装软件,结果出现了下面的错误提示:
# yum install
There was a problem importing one of the Python modules required to run yum. The error leading to this problem was:/usr/lib/python2.6/site-packages/pycurl.so: undefined symbol: CRYPTO_set_locking_callback
Please install a package which provides this module, or
verify that the module is installed correctly.It's possible that the above module doesn't match the
current version of Python, which is: 2.6.6 (r266:84292, Jan 22 2014, 09:37:14) [GCC 4.4.7 20120313 (Red Hat 4.4.7-4)]If you cannot solve this problem yourself, please go to
the yum faq at: http://yum.baseurl.org/wiki/Faq2、查看当前的环境变量
# env | grep LD
OLDPWD=/root LD_LIBRARY_PATH=:/usr/local/lib运行时链接库的目录被我设置成了这个/usr/local/lib。
取消这个运行时链接库试试:
# export -n LD_LIBRARY_PATH
# yum install busybox
已加载插件:fastestmirror 设置安装进程 Loading mirror speeds from cached hostfile * base: mirrors.btte.net * extras: mirrors.opencas.cn * updates: mirror.bit.edu.cn base | 3.7 kB 00:00 extras | 3.4 kB 00:00 updates | 3.4 kB 00:00 解决依赖关系 --> 执行事务检查 ---> Package busybox.i686 1:1.15.1-21.el6_6 will be 安装 --> 完成依赖关系计算.
.
.
果然是这个链接库的问题。
3、分析:
应该是yum依赖python的模块的模块。但是在进行加载的时候,找错目录了,结果就加载错了模块的链接库。
