在Ubuntu 14.04上安装带有RVM的Ruby 2.2.2时出错

这是什么.

我先做了：

rvm get stable
rvm install ruby-2.2.2

没有成交.它向我展示了以下内容：

$rvm install ruby-2.2.2
Searching for binary rubies,this might take some time.

There was an error(6).

No fallback URL could be found,try increasing timeout with:

    echo "export rvm_max_time_flag=20" >> ~/.rvmrc

There has been an error fetching the ruby interpreter. Halting the installation.

我告诉你增加超时时间：

echo "export rvm_max_time_flag=20" >> ~/.rvmrc

但没有交易.我也做了rvm得到了头并且在更高的超时时间重新做了但是它仍然没有好处.

我该怎么做才能在ubuntu上正确安装ruby-2.2.2？

我觉得很蹩脚,但问题是我的VM的互联网连接失败了. (我想我错过了故障排除-101,呵呵)

我更改了PC的网络,Virtual Box VM没有更新或连接到新网络.为了解决这个问题,没有一个命令(rvm得到稳定; rvm get head; rvm install ruby-2.2.2)引发了一个警告,所以我被认为是别的东西.
