Question

这是什么。我第一次做到了：

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

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.

我按照告诉的方式增加了超时时间：

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

但没有交易。我也做了rvm get head并且在更高的超时时间内重复了一次，但它仍然没有用。

如何在ubuntu上正确安装ruby-2.2.2？

Answer 1

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。要添加问题，无命令（rvm get stable; rvm get head; rvm install ruby-2.2.2）会发出警告，因此我被认为是其他问题

＆＃34;错误不应该默默地传递。＆＃34; （Python的禅宗）

在Ubuntu 14.04上安装带有RVM的Ruby 2.2.2时出错
