【问题描述】：
这是什么。 我第一次这样做：
rvm get stable
rvm install ruby-2.2.2
没有交易。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.
No binary rubies available for: ubuntu/14.04/i386/ruby-2.2.2.
Continuing with compilation. Please read 'rvm help mount' to get more information on binary rubies.
Checking requirements for ubuntu.
Requirements installation successful.

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.
我按照告知增加了超时时间：
echo "export rvm_max_time_flag=20" >> ~/.rvmrc
但没有交易。我也做了rvm get head，然后用更高的超时时间重新做了一遍，但还是不行。
如何在 ubuntu 上正确安装 ruby-2.2.2？

它没有。这可能是同样的问题。不过不确定。
