在Mac OSX 10.9.2上安装Scrapy时出错

Question

每次我尝试为一个使用scrapy的Python项目安装所需的包时，都会出现以下错误。

clang: note: this will be a hard error (cannot be downgraded to a warning) in the future

error: command 'cc' failed with exit status 1

我试过用sudo来安装，但还是不行。请告诉我可能出什么问题了。如果有帮助的话，我在尝试其他Python相关的安装时也遇到了类似的错误。

你可能没有安装Xcode的命令行工具。试着运行这个命令：

xcode-select --install
