ubuntu下配置ruby时遇到问题（二）

1， 查看系统，核心版本。

uname -a

less /proc/version

lsb_release -a 这个比较详细。

 

2,Ubuntu下apt-get update/upgrade 不能工作的解决办法。

1> gedit /etc/apt/sources.list 然后替换为下面的内容。或者替换为163的镜像文件sources.list， 在上一篇有列出。

#deb cdrom:[Ubuntu 10.04 LTS _Lucid Lynx_ - Release i386 (20100429)]/ lucid main restricted
# See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to
# newer versions of the distribution.

2> 安装sudo apt-get install curl 试试功能。如果仍然不行，

sudo apt-get install update /upgrade

如果可以就安装 sudo apt-get install curl 及其下面的命令， ruby要调为

sudo apt-cache search ruby 用来查看有哪些RUBY包可安装。
sudo apt-get install ruby #但是默认装的是1.8，我想更新到1.9的高版本。
sudo apt-get install irb  ＃装用于调试的irb
sudo apt-get install ri     ri如何使用，我还没有用会。

==========================================
sudo apt-get install curl    安装curl
curl -L get.rvm.io|bash -s stable --ruby       安装rvm。
source ~/.rvm/scripts/rvm     使其生效
rvm -v        显示rvm版本号，表示安装成功。
rvm list known     查看有哪些可安装
rvm install 1.9.3      安装ruby 1.9.3的版本。
rvm use 1.9.3 --default     设置为默认的版本。rvm可使几个版本共存。
rvm list          查看已经安装的ruby
rvm remove 1.8.0 可用来卸载一个已安装版本
sudo  apt-get install rubygems   安装gem， 为cucumber做准备。
gem list         安装成功后查看，一般会自带几个安装好的组件
gem install cucumber    安装cucumber
cucumber --version    查看即知是否安装成功。

 

3， 如果以上方法都行不通，我只有换10.04版了。
