无法在Ubuntu 16.04中使用rbenv 2.3.1安装Ruby

While installing ruby with rbenv for Ubuntu 16.04 error regarding the ruby build is shown. I've tried completely removing the rbenv and again re-installing rbenv, but all i get the following error.

使用rbenv安装ruby以获取有关ruby构建的Ubuntu 16.04错误。我已经尝试完全删除rbenv并再次重新安装rbenv，但所有我得到以下错误。

I've followed DigitalOcean's procedure for installing the rbenv as in here, and followed steps listed here for ruby_build. I've also installed all dependencies required for the build.

我按照DigitalOcean的程序安装了rbenv，如下所示，并按照此处列出的ruby_build步骤进行操作。我还安装了构建所需的所有依赖项。

Still after times of uninstall and install of rbenv problem is the same.

在卸载和安装rbenv问题之后仍然是一样的。

I was able to successfully build docker image with the following Dockerfile

我能够使用以下Dockerfile成功构建docker镜像

Some tests

一些测试

$ docker run -it --rm test rbenv version
2.3.1 (set by /usr/local/rbenv/version)

$ docker run -it --rm test ruby -v
ruby 2.3.1p112 (2016-04-26 revision 54768) [x86_64-linux]

#2

This is a known compatibility issue with openssl and ruby 2.3.x.

这是openssl和ruby 2.3.x的已知兼容性问题。

The openssl extension of Ruby version before 2.4 is not compatible with OpenSSL 1.1.x. At the moment, most Linux distributions that come with OpenSSL 1.1.0 have a separate package for OpenSSL 1.0.x.

2.4之前的Ruby版本的openssl扩展与OpenSSL 1.1.x不兼容。目前，OpenSSL 1.1.0附带的大多数Linux发行版都有一个单独的OpenSSL 1.0.x包。

You need to install the earlier version of OpenSSL or use ruby 2.4.x.

您需要安装早期版本的OpenSSL或使用ruby 2.4.x.
