ruby - rbenv - 编译 Ruby 2.1.1 时出错

Question

我在 DigitalOcean Droplet 上编译 Ruby 时遇到问题。

rbenv 0.4.0-97-gfe0b243

Ubuntu 14.04 长期支持版

Linux bashman 3.13.0-24-generic#46-Ubuntu SMP Thu Apr 10 19:11:08 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

rbenv install 2.1.1

给我:https://gist.github.com/astropanic/e4d3a3602612b3c21636

失败似乎与:

compiling readline.c
readline.c: In function ‘Init_readline’:
readline.c:1977:26: error: ‘Function’ undeclared (first use in this function)
rl_pre_input_hook = (Function *)readline_pre_input_hook;

有什么想法吗？

由于 readline 而无法构建 ruby​​ 2.1 似乎是 known error .

我使用 suggested patches 之一成功构建了它像这样:

curl -fsSL https://gist.github.com/mislav/a18b9d7f0dc5b9efc162.txt | rbenv install --patch 2.1.1

将 readline 库降级到版本 6.2.4 是一个替代建议，但我还没有尝试过。
