Question

我正在尝试安装scrapy但是当Mac OS 10.9.2无法安装libxml2时出现错误。在libxml2上阅读了一些帖子后，我已经安装了命令行工具，但仍然没有运气。

请找出错误的堆栈

Answer 1

请尝试：

export CFLAGS=-Qunused-arguments
export CPPFLAGS=-Qunused-arguments
sudo -E easy_install -U Scrapy

几乎每个easy_install / pip安装都需要在Mac OS X 10.9.2上使用这些选项，而“-E”到sudo则是将这些导出传播到超级用户环境。

在Mac 10.9.2上安装scrapy时出错。 Bugtrack_url错误
