如何在没有RVM的情况下在Ubuntu上安装Ruby 2

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

我想用apt-get install来安装它,就像ruby 1.9.1一样

有什么build议么?

  sudo apt-get -y更新
 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
光盘ruby-2.0.0-p451 /
 ./configure --prefix = / usr / local
使
 sudo make install 

从这里如何在Ubuntu 12.04上正确安装ruby 2.0.0?

UPDATE

对于ruby2.1.5

 sudo apt-get -y更新
 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
使
 sudo make install

如果你仍然看到一个老的ruby检查你的符号链接ls -la /usr/bin/ruby hector

 sudo apt-add-repository ppa:brightbox/ruby-ng-experimental && sudo apt-get update && sudo apt-get install -y ruby2.0 ruby2.0-dev ruby2.0-doc 

易于使用^ㅡ^

自从这个问题得到解答,我发现了一个新的select:

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testing,这比这里显示的替代方法更快,因为编译步骤被跳过了。

在没有RVM的情况下在ubuntu上安装ruby的更好的方法是在terminal安装rbenv ,如下所示:

 $ sudo apt-get update 

使用apt-get安装rbenv和Ruby依赖关系:

 $ 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 

现在运行这些命令如下:

 $ 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 

时间安装ruby:

 $ rbenv install 2.3.3 

这是最新和稳定的版本

 $ rbenv global 2.3.3 

检查版本

 $ ruby -v 

要禁用本地文档,因为此过程可能很漫长:

 $ echo "gem: --no-document" > ~/.gemrc 

安装捆绑软件gem来pipe理你的应用程序依赖关系:

 $ gem install bundler 

我特别喜欢ruby-install,可以在这里find: https : //github.com/postmodern/ruby-install

它会安装ruby(任何版本),JRuby等,并且还有许多其他function。
