如何在没有'LLVM'的情况下安装gcc?
我想安装一个较旧的Xcode副本,以便我可以在Ruby 1.8.7上进行Ruby开发。在我通过应用商店从4.1升级到4.3之前,这曾经在我的机器上工作。一旦我升级,我发现许多宝石都无法编译。 (TheRubyRacer,MySQL)我已经使用sudo /Developer/Library/uninstall-devtools --mode=all
命令从我的系统中删除了4.1和4.3。重启后,我确认gcc
命令失败,Xcode未列在Applications文件夹中。
我从开发人员中心下载了Xcode 4.1 for Lion并安装了它。不幸的是,我仍然无法从之前建造宝石。我从gcc检查了版本,我看到我确实安装了4.2。
gcc --version
是
i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.15.00)
