EDA虚拟机使用错误解决

在Linux中运行yum命令时显示：

There was a problem importing one of the Python modules

required to run yum. The error leading to this problem was:
   /usr/lib64/libnssutil3.so: undefined symbol: PL_ClearArenaPool
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:
2.4.3 (#1, Dec 22 2011, 12:12:01)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-50)]
If you cannot solve this problem yourself, please go to
the yum faq at:

主要是这个问题：

The error leading to this problem was:
   /usr/lib64/libnssutil3.so: undefined symbol: PL_ClearArenaPool

解决方法如下：原文

The problem is not python, it’s the LD_LIBRARY_PATH that does not include /lib64 and /usr/lib64 setting in the /etc/profiles.d/blreports.sh file.  we fixed this by pre-pending /lib64:/usr/lib64 to the LD_LIBRARY_PATH

也就是在LD_LIBRARY_PATH环境变量中加上两个路径/lib64和/usr/lib64，

方法：

1. 进入root权限，su
2. 打开当前用户下的.bashrc文件，gvim ~/.bashrc
3. 添加一行 export LD_LIBRARY_PATH=/lib64:/usr/lib64:$LD_LIBRARY_PATH
4. source一下文件.bashrc就可以了。
