python - Ipython没有可用的readline并且pip install readline错误

Question

我安装了 ipython，但它没有 readline 选项。我首先下载了 gnu readline 并编译安装。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。它仍然无法正常工作，并出现与以前相同的错误:

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 并收到以下错误。任何帮助将不胜感激:

tmaric是正确的。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。试试:

sudo apt-get install libncurses5-dev

然后通过pip再次安装readline模块

pip install readline
