如何在没有RVM的情况下在Ubuntu上安装Ruby 2

Question

我想安装Ruby 2.0使用

sudo apt-get install ruby2.0

但是ruby2.0没有可用的包

我想使用apt-get install安装它,就像ruby 1.9.1一样

有什么建议？

Answer 1

sudo apt-get -y update
sudo apt-get -y install build-essential zlib1g-dev libssl-dev libreadline6-dev libyaml-dev
cd /tmp
wget http://ftp.ruby-lang.org/pub/ruby/2.0/ruby-2.0.0-p451.tar.gz
tar -xvzf ruby-2.0.0-p451.tar.gz
cd ruby-2.0.0-p451/
./configure --prefix=/usr/local
make
sudo make install

从这里如何在Ubuntu 12.04上正确安装ruby 2.0.0？

UPDATE

对于红宝石2.1.5

sudo apt-get -y update
sudo apt-get -y install build-essential zlib1g-dev libssl-dev libreadline6-dev libyaml-dev
cd /tmp
wget http://ftp.ruby-lang.org/pub/ruby/2.1/ruby-2.1.5.tar.gz 
tar -xvzf ruby-2.1.5.tar.gz
cd ruby-2.1.5/
./configure --prefix=/usr/local
make
sudo make install

如果你仍然看到一个较旧的红宝石检查你的符号链接 ls -la /usr/bin/ruby从hector

# Adds Ruby 2.2 to Ubuntu 14.04

Answer 4

既然回答了这个问题,我在这里找到了一个新的替代方案:

https://www.brightbox.com/docs/ruby/ubuntu/

简而言之:

# For ubuntu >= 14.04 install software-properties-common
# instead of python-software-properties
sudo apt-get install python-software-properties
sudo apt-add-repository ppa:brightbox/ruby-ng
sudo apt-get update

sudo apt-get -y install ruby2.2 ruby-switch
sudo ruby-switch --set ruby2.2

我必须说,根据我的测试,这比这里显示的替代方案更快,因为跳过了编译步骤.
