问题描述

我不知道如何在 Ubuntu 上安装最新的 Ruby.

I dont know how to install the latest Ruby on Ubuntu.

首先我安装了默认的 Ruby 1.9.3，使用

First I installed the default Ruby 1.9.3, using

sudo apt-get install ruby

然后我尝试使用

sudo apt-get install ruby2.0

我的Ruby版本还是ruby 1.9.3p484 (2013-11-22 revision 43786) [x86_64-linux])"

My version of Ruby is still "ruby 1.9.3p484 (2013-11-22 revision 43786) [x86_64-linux])"

我该怎么办?

推荐答案

首先安装必备库:

sudo apt-get update
sudo apt-get install git-core curl zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev python-software-properties libffi-dev

然后安装rbenv，用于安装Ruby:

Then install rbenv, which is used to install Ruby:

cd
git clone https://github.com/rbenv/rbenv.git ~/.rbenv
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(rbenv init -)"' >> ~/.bashrc
exec $SHELL

git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build
echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bashrc
exec $SHELL

rbenv install 2.3.1
rbenv global 2.3.1
ruby -v

然后(可选)告诉 Rubygems 不要安装本地文档:

Then (optional) tell Rubygems to not install local documentation:

echo "gem: --no-ri --no-rdoc" > ~/.gemrc
