Ipython没有可用的readline和pip install readline错误 [英] Ipython no readline available and pip install readline error

问题描述

我安装了ipython但它没有readline选项。我首先下载了gnu readline并编译并安装。 DId不知道这是否是一个合适的解决方案，但这是我想到的第一件事。它仍然无法使用与以前相同的错误：

I installed ipython but it doesn't have the readline option. I first downloaded gnu readline and compiled and installed. DIdn't know whether it was a proper solution but was the first thing I thought of. It still wouldn't work to no avail with the same error as before:

WARNING: Readline services not available on this platform.
WARNING: The auto-indent feature requires the readline library

然后我尝试使用pip install readline，我收到以下错误。任何帮助将不胜感激：

Then I tried using pip install readline and I get the error below. Any help would be appreciated:

推荐答案

tmaric 是对的。我在安装iPython（Ubuntu 12.10，quantal，32位）时遇到了同样的问题。我错过了ncurses5库的开发版本。尝试：

tmaric is right. I had the same problem while installing iPython (Ubuntu 12.10, quantal, 32-bit). I was missing the dev version of the ncurses5 library. Try:

sudo apt-get install libncurses5-dev

然后通过pip再次安装readline模块

and then installing the readline module again through pip

pip install readline
