ruby - ubuntu12.04 安装 rvm 错误

Question

想装rvm,使用如下命令:

curl -L https://get.rvm.io | bash -s stable
source ~/.rvm/scripts/rvm
rvm install 1.9.3

结果安装失败,提示如下:

Searching for binary rubies, this might take some time.
Checking requirements for ubuntu.
Installing requirements for ubuntu.
Updating system - using Zsh, can not show progress, be patient...
Error running 'requirements_debian_update_system ruby-1.9.3-p448',
please read /home/songwei/.rvm/log/1378687043_ruby-1.9.3-    p448/update_system.log
Requirements installation failed with status: 100.

请问如何解决呢?网上貌似没什么方法.....

E: Some index files failed to download. They have been ignored, or old ones used instead.
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.d/*.list

Answer 1

 不能连接到 extras.ubuntu.com：http： [IP: fe80::a2b3:ccff:fee0:d988 80]

Should be the problem here. It seems quite related to the execution

sudo apt-get update && sudo apt-get install blablabla

An error occurred before execution was completed.

apt-get install

It was not executed. The dependency package of RVM was not installed

Answer 2

You can try to switch the apt-get source of ubuntu to a domestic mirror such as 163

In addition, rvm can rvm autolibs enable automatically install dependencies before installing ruby ​​

Switching the Ruby source to Taobao's server will also make the installation faster~ http://ruby.taobao.org
