我把Ubuntu Saucy Salamander（13.10）作为操作系统并试图做
rvm requirements
但总是在“更新系统”阶段出错。这是我的日志：
rvm requirements

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
/etc/apt/sources.list.d/*.list
Requirements installation failed with status: 100.

但这一切对我都有用。有人可以帮我吗？

也尝试过头：
rvm get head --autolibs=3

需求阶段的相同问题
答案 0 :(得分：2)
我按照这个建议解决了我的问题：
$ rvm autolibs read-fail
$ rvm install 1.9.3
Searching for binary rubies, this might take some time.
No binary rubies available for: ubuntu/13.10/x86_64/ruby-1.9.3-p484.
Continuing with compilation. Please read 'rvm help mount' to get more information on binary rubies.
Checking requirements for ubuntu.
Missing required packages: gawk libgdbm-dev libffi-dev
RVM autolibs is now configured with mode '2' => 'check and stop if missing',
please run `rvm autolibs enable` to let RVM do its job or run and read `rvm autolibs [help]`
or visit https://rvm.io/rvm/autolibs for more information.
Requirements installation failed with status: 1.
之后我刚安装了错过的需求包，rvm要求的结果是：
Checking requirements for ubuntu.
Requirements installation successful.
感谢大家的关注！

我通过做 -
解决了这个问题$ rvm autolibs disable
$ rvm install 1.8.7
（手动抓取并手动安装丢失的包装，在我的情况下，以下包装丢失了）
$ sudo apt get install gawk libreadline6-dev zlib1g-dev libssl-dev \
libyaml-dev libsqlite3-dev sqlite3 autoconf libgdbm-dev \
libncurses5-dev automake libtool bison libffi-dev
$ rvm requirements
$ curl -sSL https://get.rvm.io | bash -s stable --ruby
希望您通过上述步骤获得成功。

下面的解决方案是解决rvm requirment错误返回100
如果在/etc/apt/sources.list中注释了任何deb命令，而不是尝试从/etc/apt/sources.list中取消注释该命令
命令是：
$ sudo vi /etc/apt/sources.list
如果问题没有解决，请将sources.list文件替换为其他Ubuntu的sources.list
命令是：
$ mv /etc/apt/sources.list
请在执行此操作前进行备份
命令是：
$ cp /etc/apt/sources.list sources_backup.list
问题应该在这个时候解决，如果不是重新安装Ubuntu。
注意：如果sources.list文件已损坏，则会导致安装其他软件包出现问题。
答案 3 :(得分：-1)
我是通过以下方式完成的：
$ rvm autolibs disable
$ rvm install 1.9.3
