在 Linux 服务器上安装 ruby​​ 1.9.3 时出错

Question

嘿，我只是在我 ssh 进入的 linux 服务器上更新 ruby​​。我知道这有很多线程，但大多数是用于安装在 mac osx 上（我没有问题）。这是输出的错误日志：

$ rvm install 1.9.3

Answer 1

我认为您的问题是，由于 RVM 正在尝试使用命令 __rvm_make -j48 编译 ruby​​（它告诉编译器尝试在 48 个不同的作业中并行化编译），因此您的主机系统空间不足可做所以。在我找到一个可能的解决方案之前，这里有一些高层次的想法：

1. 生产系统通常不应该编译自己的 Ruby 版本。相反，将编译后的二进制文件发送到节点（例如，作为 Debian 包），甚至不安装 RVM。

2. rvm 做了很多魔术来尝试向最终用户隐藏其所做的细节，但根据我的经验，这比它的价值更麻烦。使用 chruby 或 rbenv 并仅在需要时构建 Ruby。

无论如何，对于您当前的问题，我认为您最好的选择是尝试将-j 标志覆盖为较小的值。有几种方法，但先试试这个：

rvm install 1.9.3 -j 1                # from http://cheat.errtheblog.com/s/rvm

如果这没有帮助，请仔细检查 __rvm_make -j 48 中的 -j 参数是否在日志中实际更改为 1。如果是这样，请尝试较小的数字。如果没有，那么试试这个：

MAKEFLAGS=-j1 rvm install ruby-1.9.3  # from https://twitter.com/avdi/status/130720270733410305

希望是其中之一！
