======================================

msys2 出现这个错误

网上的解决方案 通常是这个 

------------------------------------

解决方案： 
在本身的用户根目录下面新建.gdbinit文件 
cd ~ 
vim .gdbinit 
而后复制以下代码到.gdbinit文件：

python
import sys 
sys.path.append("/usr/share/gcc-4.8/python")
end
-------------------------------

但实验后 发现没有效果

搜索 gdbinit 发现 /etc/ 底下有一个 gdbinit

python
import sys
sys.path.insert(0, sys.path[0] + '/../../gcc-6.3.0/python')
from libstdcxx.v6.printers import register_libstdcxx_printers
register_libstdcxx_printers (None)
end

发现这里的gcc-6.3.0 和 msys2里带的 gcc的版本不同 把

'/../../gcc-6.3.0/python' 改为  '/../../gcc-7.3.0/python'  就能够了。。。
