用扩展安装gem总是失败 [英] Installing gems with extensions always fails

问题描述

我刚刚安装了Ubuntu 13.04服务器，并安装了RVM 1.21.11，Ruby 1.9.3-p448和Rubygems 2.0.5。

许多宝石，例如成功安装了 mongo ，， aws-s3 和 json 。

然而，编译扩展的gem失败。我尝试安装 nokogiri ， mongo_ext 和 bson_ext 。他们都以同样的方式失败，如下所示。

任何想法如何解决这个问题？

解决方案

是由RubyGems中的一个错误引起的。它已在 8d1751c6 中得到修复。

在RubyGems v2.0.6发布之前，解决方法是手动应用 8d1751c6 。

I just setup an Ubuntu 13.04 server, and installed RVM 1.21.11, Ruby 1.9.3-p448, and Rubygems 2.0.5 .

Many gems, such as mongo, awesome_print, aws-s3, and json, installed successfully.

However, gems that compile an extension fail. I've tried to install nokogiri, mongo_ext, and bson_ext . They all fail in the same way, as shown below.

Any idea how to fix this?

解决方案

This was caused by a bug in RubyGems. It was fixed in 8d1751c6.

Until RubyGems v2.0.6 is released, a workaround is to apply 8d1751c6 manually.
