我有一个python3.3.1安装ubuntu（虽然默认是 python2.6.5）。我通常使用virtualenvwrapper.
我想安装ipython支持python3。所以我这样做了
>>workon envpy331
(envpy331)damon@ubuntu:~$
(envpy331)damon@ubuntu:~$pip install ipython
....
安装完成后，我试了
(envpy331)damon@ubuntu:ipython3
(envpy331)damon@ubuntu:

看到这个我尝试安装 readline
(envpy331)damon@ubuntu:pip install readline
此下载并尝试安装 readline 但失败
/usr/bin/ld: cannot find -lncurses
collect2: ld returned 1 exit status
error: command 'gcc' failed with exit status 1
当我试图定位 libncurses 时，我发现系统中安装了版本 5
:locate libncurses
