Rails 3安装错误：“@ cert_chain的值无效” [英] Rails 3 install error: "invalid value for @cert_chain"

问题描述

我试图在一台新的OS X Snow Leopard机器（安装了开发工具）上安装Rails 3，当我 sudo gem install rails 时，我得到以下错误：

 错误：执行gem时（Gem :: FormatException）
 builder-2.1.2对于@cert_chain 
  

有一个无效值，并且更新失败。有没有人见过这个？我 grep 编辑了'cert_chain'的builder-2.1.2目录，但找不到任何线索。

Ruby版本是1.8.7

OS X 10.6.6

谢谢！

解决方案

这是Rubygems 1.7.1版的问题。升级到1.7.2或更高版本，或降级到1.6.2，修复此问题。

升级（首选）：

  gem update  - 系统
  

降级：

  gem update --system 1.6.2 
  

I'm trying to install Rails 3 on a new OS X Snow Leopard machine (with dev tools installed), and when I sudo gem install rails, I get the following error:

ERROR:  While executing gem ... (Gem::FormatException)
builder-2.1.2 has an invalid value for @cert_chain

And the update fails. Has anyone seen this before? I greped the builder-2.1.2 directory for 'cert_chain,' but couldn't find any clues.

Ruby version is 1.8.7

OS X 10.6.6

Thanks!

解决方案

This is an issue with Rubygems version 1.7.1. Upgrading to 1.7.2 or above, or downgrading to 1.6.2, fixes this.

To upgrade (preferred):

gem update --system

To downgrade:

gem update --system 1.6.2
