在像交互式python shell这样的shell中,你通常可以使用箭头键在当前行中移动或获取以前的命令(使用向上箭头)等.
但是在我进入另一台机器并从python那里开始之后,我会得到以下会话:
>>> import os
>>> ^[[A
最后一个角色来自向上箭头.或者,使用左箭头:
>>> impor^[[D
我怎样才能解决这个问题？
在常规bash中,箭头键工作正常.奇怪的行为只是在交互式python(或perl等)shell中.
如何重复上一个命令？通常的键:Up,Ctrl + Up,Alt-p不起作用.他们产生荒谬的人物.

当我在我的osx上安装ipython并运行它时,我收到以下警告:

我已经安装了readline,并且不使用最初安装的系统python /Library/Frameworks/Python.framework/Versions/2.7/bin/python$./usr/bin/python版本2.7 的要点如下所示
