我在使用ubuntu 12.04在我的机器上安装rvm ROR时遇到问题
这是我得到的输出：
输出＃1：
Searching for binary rubies, this might take some time.
No binary rubies available for: ubuntu/12.04/i386/ruby-1.8.7-p371.Continuing with compilation.
Please read 'rvm mount' to get more information on binary rubies.
Installing requirements for ubuntu, might require sudo password.
在更新行的最后我得到了这个：
输出＃2：
There has been error while updating 'apt-get', please give it some time and try again later.
For 404 errors check your sources configured in:
/etc/apt/sources.list
/etc/apt/sources.list.d/*.list

尝试在命令行上单独运行sudo apt-get update。您的Ubuntu可能已经过时，其存储库可能已过时。因此，apt-get update本身可能无法在您的计算机上运行。
要跳过该问题，请运行以下命令：
# Disable RVM from trying to install necessary software via apt-get
rvm autolibs disable
# Then try installing Ruby:
rvm install 1.8.7
如果您仍然遇到错误，请查看您是否可以直接执行apt-get install而不执行apt-get update（失败）：
# Try to see if you can manually install the necessary software
sudo apt-get install build-essential openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison subversion pkg-config
如果这也无效，请粘贴apt-get update输出。
