没有二进制红宝石可用于：osx / 10.8 / x86_64 / ruby​​-1.9.2-p320

Question

有一篇为期两年的博客文章here解释如何修复“你必须首先安装开发工具”的错误'Nokogiri附带的错误，如果你在安装后升级到Mountain Lion就会出现问题RVM。在博客文章中他说你必须做

rvm update head
rvm --force install 1.9.2
gem install bundle

## in your rails app
bundle
Installing nokogiri (1.4.2) with native extensions
 ...

rvm update head现已更改为rvm get head。但是，之后我盲目地做了

rvm --force install 1.9.2

并收到此错误消息

rvm --force install 1.9.2
Searching for binary rubies, this might take some time.

换句话说，它指示我回到同一篇博文。

看看RVM网站，我一味地做了

rvm install 1.9.2

我收到了这个错误

未安装ruby-1.9.2-p320。 要安装do：'rvm install ruby​​-1.9.2-p320'

按照其说明，我做了rvm install ruby​​-1.9.2-p320并得到了相同的二进制文件错误

任何人都可以提供一些指导

Answer 1

你需要运行：

rvm get head
rvm autolibs enable
rvm use --install 1.9.2
bundle install

Answer 2

首先，在您熟悉安装“RVM要求”和Ruby之后，从Xcode内部安装“命令行工具”。
