- 刚刚升级到Python3.6.1发现某些键无法正常使用的情况
[root@yuhai ~]# pythonPython 3.6.1 (default, Mar 22 2017, 22:29:50) [GCC 4.8.5 20150623 (Red Hat 4.8.5-11)] on linuxType "help", "copyright", "credits" or "license" for more information.>>> ///^[[3~^H^H^H^H^CKeyboardInterrupt>>> ^[[3~^H^[[B^[[C^[[D^C^CKeyboardInterrupt>>> exit ()
原因：Readline包缺少
解决方法：安装Readline包，并重新编译Python
- 查看Readline安装包是否完整
[root@yuhai ~]# rpm -qa | grep readlinereadline-6.2-9.el7.x86_64[root@yuhai ~]# - 安装完整的readline包
[root@yuhai ~]# yum install -y readline*- yum安装出错
[root@yuhai ~]# yum install -y readline File "/usr/bin/yum", line 30 except KeyboardInterrupt, e: ^SyntaxError: invalid syntax解决方法链接：https://my.oschina.net/u/3041278/blog/865340
- 现在安装完整的readline包
[root@yuhai ~]# yum install -y readline*以下省略- 删除安装的Python3.6.1
[root@yuhai ~]# rm -rf /usr/local/python3* #删除所编译的Python3.6.1[root@yuhai ~]# rm -rf /usr/bin/python #删除软连接[root@yuhai ~]# ls /usr/local/python3* #检查是否删除ls: cannot access /usr/local/python3*: No such file or directory[root@yuhai ~]# ls /usr/bin/python ##检查是否删除ls: cannot access /usr/bin/python: No such file or directory[root@yuhai ~]# - 重新安装Python3.6.1
