解决无法运行Terminator出现以下问题： File "/usr/bin/terminator"...SyntaxError: invalid syntax

在安装或者启动Terminator时可能出现这个问题：

lin@Dev:~$ terminator
  File "/usr/bin/terminator", line 123
    except (KeyError,ValueError), ex:
                                ^
SyntaxError: invalid syntax

错误原因：语法错误．这是因为Terminator的安装或者运行需要python2的环境，但是却用python3的环境去运行Terminator了．

我们查看Terminator的启动脚本文件，在'/usr/bin'下．

vi /usr/bin/terminator

#!/usr/bin/python
#    Terminator - multiple gnome terminals in one window

第一行标示使用的是系统默认的python脚本．

系统安装的python的版本有两个分别是python2.7和python3.6，当python链接到python2.7时，程序运行正常，链接到python3.6时出现以上的语法错误。

解决方法：

1. 将系统默认的python版本链接到2(不建议)

2.  修改terminator的启动脚本(/usr/bin/terminator)如下：

#! /usr/bin/python2

保存退出重新运营terminator，成功．
