SecureCRT使用BackSpace与python shell 方向键乱码

1. 解决backspace和delete的乱码： 
在securecrt的 工具栏–>options–>session–>terminal–>emulation–>mapped keys 页面，勾选“other mappings”的两个选项，如下图： 

2、python shell 方向键乱码

[root@bigdata003 ~]# python
Python 2.7.15 (default, Jan 24 2019, 15:36:44) 
[GCC 4.4.7 20120313 (Red Hat 4.4.7-23)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> ^[[A^[[A

如果出现以上情况，那么需要安装一下包，并重新编译python： 
yum install readline-devel 
./configure –prefix=/usr/local/python2.7 
make all 
make install 
make clean 
make distclean
