Question

我试图安装wpscan 我有macbook专业版10.9.2 我正在运行小牛osx。

我跟着指令：

git clone https://github.com/wpscanteam/wpscan.git 
cd wpscan 

，然后我试图

sudo gem install bundler && bundle install --without test development 

之后，我得到这个错误：

An error occurred while installing ffi (1.9.3), and Bundler cannot continue. 
Make sure that `gem install ffi -v '1.9.3'` succeeds before bundling. 

任何人都可以帮助我吗？ 谢谢。

我的猜测是，这是你的问题（这里使用JSON，但它似乎是同样的问题的变体）：Ruby Gem install Json fails on Mavericks and Xcode 5.1 - unknown argument: '-multiply_definedsuppress'

长话短说：临时解决方法是“ARCHFLAGS = -Wno错误= unused-command-line-argument-hard-error-in-future gem install [gem]“其中[gem]是其命令行参数导致崩溃的特定gem。
