安装Sqlite3 Gem错误

Question

在安装了XCode 4.2的OS X Lion上安装Sqlite3 gem时出现以下错误:

$ gem install sqlite3
Building native extensions.  This could take a while...
ERROR:  Error installing sqlite3:
    ERROR: Failed to build gem native extension.

链接到/usr/bin/llvm-gcc-4.2是唯一的修复(似乎有点黑客)?还是我错过了什么?

Answer 1

看起来XCode 4.2不安装gcc-4.2，而是安装llvm-gcc-4.2。显然，苹果觉得LLVM已经足够成熟，可以成为GCC的超级种子。

我能想到两个选择。你应该能够选择其中之一，并且OK。

1. Symlink LLVM using sudo ln -s /usr/bin/llvm-gcc-4.2 /usr/bin/gcc-4.2 .
