如何在没有root访问权限的情况下安装rvm？
我想在没有rubygem的机器上安装travis gem，而我没有root。 （我想加密与travis一起使用的东西。）我决定尝试安装rvm，因为https://rvm.io/rvm/install表明这是一种简单的方法来安装没有root的ruby。 但是，我马上遇到了问题：

所以我再试一次：

尝试rvm install 1.8给出了关于debian要求的相同错误消息。 除了放弃rvm和从源代码构建ruby之外，我还有其他选择吗？
TL; DR
您缺少构建Ruby所需的包依赖项。
包和Autolib
您面临的问题是最近（某些）版本的RVM使用名为autolibs的function来尝试安装包依赖项。 当然，您需要sudo访问权限才能安装系统软件包。 你可以尝试安装一个Ruby解释器：
-
--autolibs=read-only– 以避免sudo错误，但这不太可能导致工作二进制文件。 -
--autolibs=rvm_pkg– 将使用旧的rvm pkg install ...来安装缺少的依赖项，如果它们可以由RVM提供，这将花费很长时间并且不能保证工作。 -
--autolibs=read-fail– 为了避免sudo错误，它将生成要为下一节安装的依赖项列表。
请求Root安装包依赖项
通常，最简单的解决方案是让root用户安装 RVM期望的软件包 。 在做其他任何事情之前，这应该是你的第一站。 使用静态二进制文件或手工构建所有依赖项可能有合理的理由，但如果可以的话，为什么不以简单的方式做事情呢？
尝试预建的静态二进制文件
如果无法安装必要的软件包，可以尝试使用rvm list remote命令查看是否有任何可由RVM安装的系统预构建二进制文件。 如果您缺少软件包，那么您可能希望查找可以与rvm mount命令一起使用的静态二进制文件。 您甚至可以在另一个系统上构建解释器，并使用适当的远程URL挂载它; 有关详细信息，请参阅rvm help mount 。
