Answer 1

我也有Ubuntu 14.04,我必须让它工作.分享我的所作所为,以防它适合你.

我修补了文件ext/readline/readline.c替换行1886:

rl_pre_input_hook = (Function *)readline_pre_input_hook;

同

rl_pre_input_hook = (rl_hook_func_t *)readline_pre_input_hook;

然后我尝试再次制作它并且它有效.

Answer 2

这是我在 Ubuntu 14.04 Server 版本上的解决方案。

我需要安装下划线

sudo apt-get install libreadline6 libreadline6-dev

然后，问题就解决了。
