我想将travisgem 安装在没有 ruby​​ gems 并且我没有 root 的机器上。（我想加密一些东西以供 travis 使用。）我决定尝试安装 rvm，因为https://rvm.io/rvm/install表明这是一种无需 root 即可安装 ruby​​ 的简单方法。但是，我马上遇到了问题：

尝试rvm install 1.8给了我关于 debian 要求的相同错误消息。除了放弃 rvm 并从源代码构建 ruby​​ 之外，我还有其他选择吗？

TL;博士

您缺少构建 Ruby 所需的包依赖项。

包和自动库

您面临的问题是 RVM 的最新（ish）版本使用了一个名为autolibs的功能，它试图安装包依赖项。当然，您需要sudo访问权限才能安装系统包。您可以尝试使用以下命令安装 Ruby 解释器：

  • --autolibs=read-only- 避免sudo错误，但这不太可能导致二进制文件正常工作。
  • --autolibs=rvm_pkgrvm pkg install ...-如果 RVM 可以提供缺少的依赖项，则将使用旧的依赖项来安装它们，这将花费很长时间并且不保证可以正常工作。
  • --autolibs=read-fail- 为避免sudo错误，它将为下一部分生成要安装的依赖项列表。

要求 Root 安装软件包依赖项

一般来说，最简单的解决方案是让 root安装RVM 期望的包。这真的应该是您在做任何其他事情之前的第一站。使用静态二进制文件或手动构建所有依赖项可能有正当理由，但如果可以的话，为什么不以简单的方式做事呢？

尝试预建的静态二进制文件

如果您无法安装必要的软件包，您可以尝试使用该rvm list remote命令查看是否有任何可通过 RVM 安装的系统预构建二进制文件。如果您缺少包，那么您可能需要查找可以与该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 安装它；详情见rvm help mount。
