Question

我正在使用sudo easy_install Scrapy尝试在我的Mac上安装Scrapy（运行Mac OS 10.9.2）。

当我收到以下错误时，安装似乎接近完成。我似乎无法弄明白。有人可以帮忙吗？

修改

使用pip install scrapy，我收到以下错误。所以这两种选择都无效

目前，您可以在构建之前执行以下操作来解决此问题：

export CFLAGS=-Qunused-arguments
export CPPFLAGS=-Qunused-arguments

这应该通知编译器将这些错误转回警告。最终，如错误消息所示，这些将是硬错误。从长远来看，软件包维护者必须编辑软件包以不使用-mno-fused-madd。

无法使用easy_install或pip在我的Mac上安装scrapy
