I have been trying to get Scrapy installed using pip in order to scrape a NBA schedule and scores for the season. Been working on simply trying to get it installed for the last 6 hours. I have followed the set up instructions word for word but still am not able to get it to work. Any help would be greatly appreciated. The terminal window output is below. Thanks so much! Using mac osx btw.

推荐答案

请按照以下步骤操作:

首次安装密码:

brew install pkg-config libffi
export CFLAGS=-Qunused-arguments
export CPPFLAGS=-Qunused-arguments
export PKG_CONFIG_PATH=/usr/local/Cellar/libffi/3.0.13/lib/pkgconfig/
pip install cryptography

然后使用以下命令安装lxml:

Then install lxml using:

xcode-select --install

然后使用以下命令安装scrapy:

And then install scrapy using:

pip install Scrapy

或

easy_install Scrapy
