之前装Python3版本可能把ubuntu虚拟机环境弄坏了，导致gdb功能异常报错

test@ubuntu:/usr/bin$ gdb
Could not find platform independent libraries <prefix>
Could not find platform dependent libraries <exec_prefix>
Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
Fatal Python error: Py_Initialize: Unable to get the locale encoding
ModuleNotFoundError: No module named 'encodings'

通过命令readelf -d gdb查看依赖库

test@ubuntu:~/Share/LiteSDK/.objs/ubuntu/sdk/test$ readelf -d /usr/bin/gdb
