首先，我尝试了常见的 rvm 安装。
rvm 安装 1.9.2
但是，显示了以下错误:
The provided compiler '/usr/bin/gcc' is LLVM based, it is not yet fully supported by ruby and gems, please read `rvm requirements`.
然后我跑
rvm requirements
并发现以下输出部分很有用
Right now Ruby requires gcc to compile, but Xcode 4.2 and later no longer ship with gcc. Instead they ship with llvm-gcc (to which gcc is a symlink) and clang, neither of which are supported for building Ruby. Xcode 4.1 was the last version to ship gcc, which was /usr/bin/gcc-4.2.
Xcode 4.1 and earlier:
- Ruby will build fine.
Xcode 4.2 and later (including Command Line Tools for Xcode):
- If you have gcc-4.2 (and friends) from an earlier Xcode version, Ruby will build fine.
- If you don't have gcc-4.2, you have two options to get it:
* Install apple-gcc42 from Homebrew
* Install osx-gcc-installer
Homebrew:
If you are using Homebrew, you can install the apple-gcc42 and required libraries from homebrew/dupes:
brew update
brew tap homebrew/dupes
brew install autoconf automake apple-gcc42
rvm pkg install openssl
This can live side by side with an existing Xcode 4.2+ install or Command Line Tools for Xcode.
所以我尝试了:
brew update
brew tap homebrew/dupes
brew install autoconf automake apple-gcc42
但是，我得到了以下错误
Warning: Could not link apple-gcc42. Unlinking...
Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
You can try again using `brew link apple-gcc42'

/usr/local/Cellar/apple-gcc42/4.2.1-5666.3: 104 files, 75M, built in 23 seconds
kanitw:shell.venturelab.com kanitw$ brew link apple-gcc42
Linking /usr/local/Cellar/apple-gcc42/4.2.1-5666.3... Warning: Could not link apple-gcc42. Unlinking...
Error: Could not symlink file: /usr/local/Cellar/apple-gcc42/4.2.1-5666.3/include/gcc
/usr/local/include is not writable. You should change its permissions.
我最好的解决方案是什么？我有点记得在某个地方我不应该将 sudo 与 brew 一起使用，因为我会弄乱整个安装。
最佳答案
您可以更改/usr/local 目录所有者
sudo chown -R `whoami` /usr/local
但是，如果你安装了 mysql，你必须修复它的所有者
sudo chown -R mysql:mysql /usr/local/mysql
关于ruby - 由于符号链接(symbolic link)错误，无法在 Mac OSX 10.8.1 中安装 ruby-1.9.2，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/12578220/
