ruby - 无法在安装了 xcode 和 rvm 的 Mac OSX 10.9.1 上安装 Jekyll

Question

在 Mac OSX 10.9.1 上安装 Jekyll 时运气不佳

我安装了 rvm 和 Xcode 5.0.2。

当我运行 gem install jekyll 时，它告诉我...

Permission denied - /Users/Vivid/.rvm/gems/ruby-1.9.2-p320/extensions/x86_64-darwin-12

然后我运行 sudo gem install jekyll 然后我得到:

ERROR:  Error installing jekyll:
    ERROR: Failed to build gem native extension.

make failed, exit code 2

Gem files will remain installed in /Users/Vivid/.rvm/rubies/ruby-1.9.2-p320/lib/ruby/gems/1.9.1/gems/fast-stemmer-1.0.2 for inspection.

这是 /Users/Vivid/.rvm/gems/ruby-1.9.3-p327/gems/fast-stemmer-1.0.2/ext/gem_make.out 的内容:

显然有些事情是不对的。任何建议都会很神奇，干杯。

您需要安装gcc-4.2。确保你有 Homebrew installed并运行

brew install apple-gcc42

确保在运行时看到满意的输出:

which gcc-4.2

然后尝试重新运行:

sudo gem install jekyll

轰!已安装。
