ipython上下箭头奇怪的行为 [英] ipython up and down arrow strange behaviour

问题描述

在我的ipython安装中，我遇到了这个奇怪的问题，我无法通过向上和向下箭头可靠地移动命令历史......很多时候它不起作用（按键时没有任何反应）。有时在命令末尾写正常字符也行不通。

In my installation of ipython I have this strange problem where I cannot reliably move through command history with up and down arrows... a lot of the time it just doesn't work (nothing happens on the key press). Also sometimes writing normal characters at the end of the command just doesn't work.

我的系统：Mac OSX Lion

我已经安装了readline ...

推荐答案

确保在 ipython之前安装了readline 。

Make sure you installed readline before ipython.

sudo pip uninstall ipython

sudo pip安装readline ipython
