ruby - 在 Mac OS Mavericks (10.9.2) 上安装 Jekyll 时出错

Question

尝试在 OSX Mavericks 上安装稳定版的 Jekyll。我安装了 Xcode 和命令行工具，但出现此错误:

sudo gem install jekyll

ERROR:  Error installing jekyll:

Answer 1

您的问题出现在 Xcode 5.1 中。为了避免与 MacOS 的 ruby​​ 版本(这个和许多其他版本)相关的许多问题，您真的应该使用 RVM .

如果您还没有，请先安装 Homebrew:(这不是绝对必要的，但允许我们安装 ruby​​ 及其依赖项而无需 looong 编译)

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

然后，以下命令将安装 RVM 和最新版本的 Ruby:

\curl -L https://get.rvm.io | bash -s stable --ruby

检查一切是否正常:

ruby --version

您现在可以安装 Jekyll:

gem install jekyll

---

现在，如果您真的不想使用 RVM，您可以执行:

sudo ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future gem install jekyll

但我敢打赌还会有更多的问题。
