Cygwin下安装vim后,vim中退格键无法正常使用的解决方法

问题描述：

在Cygwin中安装完vim后

进入vim，发现上下左右键和退格键都无法正常使用

问题分析：

首先考虑到的就是缺少vim的配置文件，首先查看/etc路径下是否有vim的配置文件

admin@ThinkPad /etc
$ cd /etc

admin@ThinkPad /etc
$ ls -a|grep vimrc发现/etc下没有vim的全局配置文件，然后再查找当前用户的vim配置文件.vimrc

admin@ThinkPad /etc
$ cd ~

admin@ThinkPad ~
$ ls -a|grep .vimrc发现也没有，可以确定是缺少vim的配置文件导致部分按键设置没有生效

解决方式：

从文件共享目录中拷贝一个vim的配置文件至当前用户家目录下即可

admin@ThinkPad ~
$ cp /usr/share/vim/vim74/vimrc_example.vim ~/.vimrc
admin@ThinkPad ~
$ cat ~/.vimrc

" Use Vim settings, rather than Vi settings (much better!).
