当安装了Xcode 4.3.2并且缺少gcc时，如何使用RVM安装Ruby 1.9.3? [英] How to use RVM to install Ruby 1.9.3 when Xcode 4.3.2 is installed and gcc is missing?

问题描述

我安装了带有Lion的新iMac并安装了Xcode 4.3.2.跑步后

I got a new iMac with Lion and installed Xcode 4.3.2. After running

curl -L get.rvm.io | bash -s stable

我打开了一个新的bash，并使用了

I opened up a new bash, and used

$ rvm install 1.9.3

安装Ruby 1.9.3，但出现错误，日志显示C编译器不存在.然后rvm requirements说:

to install Ruby 1.9.3, but there were errors and the log said that the C compiler is not there. And rvm requirements says:

$ rvm requirements
  [...]
Xcode 4.3+ users
- please be warned
- only ruby-1.9.3-p125+ is partially supported
- in case of any compilation issues:
 * downgrade to Xcode 4.1
 * uninstall Xcode and install osx-gcc-installer
and reinstall your rubies.

那么这是否意味着我可能需要降级到Xcode 4.1?如果我想保留Xcode 4.3.2怎么办?那么1.9.3-p125 +是否可以工作，但只能部分工作?

So does that mean I might need to downgrade to Xcode 4.1? What if I want to keep Xcode 4.3.2? Then will 1.9.3-p125+ be able to work, but only partially?

更新:或者安装Ruby 1.9.2怎么样-它将与最新的Rails 3.2.3一起使用吗?如果是这样，如何添加gcc? (使用Xcode的gcc吗?)

Update: or how about installing Ruby 1.9.2 -- will it work with the latest Rails 3.2.3? If so, how to add gcc? (using Xcode's gcc?)

推荐答案

要安装1.9.2或更低版本，您需要按照此博客文章中的说明进行操作.它概述了如何获取与Xcode不冲突但可以用于构建Ruby的GCC副本.

To install 1.9.2 or lower you need to follow the instructions in this blog post. It outlines how it get a copy of GCC which does not conflict with Xcode but can be used to build Ruby.

Xcode 4.3，Homebrew和Ruby .

您无法安装osx-gcc-installer，因为它会与Xcode 4.3.2冲突，从而覆盖llvm-gcc和clang的工作版本.

You cannot install the osx-gcc-installer as it will conflict with Xcode 4.3.2, overwriting the working versions of llvm-gcc and clang.
