ruby – 如何在没有root访问权限的情况下安装rvm？

我想在没有宝石宝石的机器上安装travis宝石,而我没有root. (我想加密一些用于travis的东西.)我决定尝试安装rvm,因为 https://rvm.io/rvm/install表示这是一个简单的方法来安装没有root的ruby.但是,我马上遇到了问题：

尝试rvm安装1.8给我相同的关于debian要求的错误信息.除了放弃rvm和从源代码构建ruby之外,我有什么选择吗？

解决方法

TL; DR

您缺少构建Ruby所需的包依赖关系.

软件包和Autolibs

您所面临的问题是最近(ish)版本的RVM使用一个名为autolibs的功能来尝试安装软件包依赖关系.当然,您需要sudo访问来安装系统包.您可以尝试安装一个Ruby解释器：

> –autolibs =只读 – 以避免sudo错误,但这不太可能导致一个正常的二进制文件.
> –autolibs = rvm_pkg – 将使用旧的rvm pkg install …安装缺少的依赖关系,如果它们可以由RVM提供,这将需要很长时间,并不能保证工作.
> –autolibs = read-fail – 为避免sudo错误,它将生成下一节安装的依赖关系列表.

询问Root安装软件包依赖关系

一般来说,最简单的解决方案是要求root到install the packages RVM期望.在做任何事情之前,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法的原因,但是为什么不做简单的方法呢？

尝试预制,静态二进制

如果您无法安装必需的软件包,可以尝试使用rvm list remote命令查看是否有可以由RVM安装的系统的预构建二进制文件.如果您缺少软件包,那么您可能希望查找可以使用rvm mount命令的静态二进制文件.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进行安装;有关详细信息,请参见rvm help mount.
