centos 7 安装scrapy报错说找不到scrapy需要的Twisted13.0以上版本？

• Collecting Twisted>=13.1.0 (from Scrapy)
• Could not find a version that satisfies the requirement Twisted>=13.1.0 (from Scrapy) (from - versions: )
• No matching distribution found for Twisted>=13.1.0 (from Scrapy)

执行以下命令

wget https://twistedmatrix.com/Releases/Twisted/17.1/Twisted-17.1.0.tar.bz2
tar -jxvf Twisted-17.1.0.tar.bz2
cd Twisted-17.1.0
python setup.py install

然后欢乐的安装scrapy吧

pip install scrapy

Windows安装时候提示没有vc++？
