0x01 安装方法

方法一， 使用pip直接安装（亲测无效）

 $ pip install peda

方法二， 使用源码安装

$ git clone https://github.com/longld/peda.git ~/peda
$ echo "source ~/peda/peda.py" >> ~/.gdbinit 

0x02 真相

就LZ的亲身实战发现，第一种方法是行不通的。广大吃瓜群众直接使用使用第二中。

使用方法一安装后启动gdb，报错信息如下：

    $ gdb

        except Exception, e:
                        ^
    SyntaxError: invalid syntax
    (gdb) quit

能看到peda.py的语法报错，但是对于python2.7用了这么多年的我来说，很容易发现这句话并没有语法错误。究竟是出了神么问题？ 难道python的解释器版本运行的是python3？ 到带着疑问修改了代码，增加了print 语句，验证了这个想法。

玛莎卡，为啥会运行python3？

查下gdb的连接库，确定，这货自己绑定了python3的库。

不再纠结，直接上源码安装，完美运行。
