解决gdb报错：Failed to import the site module，No module named '_sysconfigdata_m'

最近使用gdb，一直报错：

Failed to import the site module

Traceback (most recent call last):

ImportError: No module named '_sysconfigdata_m'

吾只搜索了开始的，说是跟python有关．后来同事搜索了最后一句错误，找到了解决办法：

/

# cd /usr/lib/python3.4
# ln  -s /usr/lib/python3.4/plat-i386-linux-gnu/_sysconfigdata_m.py .
