如何在Ubuntu 14.04上安装Ruby 2.1.4(How to install Ruby 2.1.4 on Ubuntu 14.04)

编程入门行业动态更新时间:2024-10-24 14:27:50

我不知道如何在Ubuntu上安装最新的Ruby。

首先我安装了默认的Ruby 1.9.3，使用

sudo apt-get install ruby

然后我试图安装2.0版本使用

sudo apt-get install ruby2.0

我的Ruby版本还是“ruby 1.9.3p484（2013-11-22修订版43786）[x86_64-linux]）”

我该怎么办？

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

First I installed the default Ruby 1.9.3, using

sudo apt-get install ruby

Then I tried to install the 2.0 version using

sudo apt-get install ruby2.0

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

What should I do?

最满意答案

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：

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不安装本地文档：

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

警告！！！ Gnome-Shell有问题。见下面的评论。

First of all, install the prerequisite libraries:

Then install rbenv, which is used to install Ruby:

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

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