Question

我在使用DigitalOcean Droplet编译Ruby时遇到问题。

rbenv 0.4.0-97-gfe0b243

Ubuntu 14.04 LTS

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

给了我：https://gist.github.com/astropanic/e4d3a3602612b3c21636

失败似乎与：

有关

有什么想法吗？

Answer 1

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

我使用suggested patches中的一个成功构建它：

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是另一种建议，但我没有尝试过。

以下将解决您的问题：

sudo apt install libssl1.0-dev

rbenv - 编译Ruby 2.1.1时出错
